Quotes & Sayings About Mammals

Newborns can be up to 20 percent of their mother's mass in the smaller cetacean species. This is extreme. Few, if any, large terrestrial mammals give birth to young that are more than 15 percent of their own weight.26 The minimum size for a newborn marine mammal seems to be about 0.6 meters long and five kilograms. — Hal Whitehead

When did the mammals get confusing? Who can't look at a baby and a puppy and see the differences? You can't leave babies at home alone with a chew toy when you go to the movies. Babies will not shimmy under the covers to sleep on your feet when you're cold. Babies, for all their many unarguable charms, will not run with you in the park, or wait by the door for your return, and, as far as I can tell, they know absolutely nothing of unconditional love. — Ann Patchett

Mkhaya's herd is a good-sized group - sixteen in all, counting the calves - and even though they are the largest land mammals on earth, they are not always easy to find. Elephants, it runs out, are surprisingly stealthy. — Thomas French

I have always found small mammals enough like ourselves to feel that I could understand what their lives would be like, and yet different enough to make it a sort of adventure and exploration to see what they were doing. — Donald Griffin

Diet is a matter of personal preference, but if you're interested in the advanced states of meditation, eating mammals should be avoided. They have a more evolved consciousness and can affect your attention field greatly. — Frederick Lenz

Eating what stands on one leg [mushrooms and plant foods] is better than eating what stands on two legs [fowl], which is better than eating what stands on four legs [cows, pigs, and other mammals]. — Michael Pollan

Aristotle's scala naturae, which runs from God, the angels, and humans at the top, downward to other mammals, birds, fish, insects, and mollusks at the bottom. — Frans De Waal

with rare exceptions (chiefly the social insects), mammals and birds are the only organisms to devote substantial attention to the care of their young; an evolutionary development that, through the long period of plasticity which it permits, takes advantage of the large information-processing capability of the mammalian and primate brains. Love seems to be an invention of the mammals. — Carl Sagan

The Americas were a great laboratory of evolutionary experimentation, a place where animals and plants unknown in Africa and Asia had evolved and thrived. But no longer. Within 2,000 years of the Sapiens' arrival, most of these unique species were gone. According to current estimates, within that short interval, North America lost thirty-four out of its forty-seven genera of large mammals. South America lost fifty out of sixty. The sabre-tooth cats, after flourishing for more than 30 million years, disappeared, and so did the giant ground sloths, the oversized lions, native American horses, native American camels, the giant rodents and the mammoths. Thousands of species of smaller mammals, reptiles, birds and even insects and parasites also became extinct (when the mammoths died out, all species of mammoth ticks followed them to oblivion). — Yuval Noah Harari

Whiskey grunted. By his count, he and Patrick had six days to go before he hauled the kid out by his ear on field work and let Fly Bait plan the destruction of all testosterone-based land mammals on general principal. — Amy Lane

Touch' is a multi-faceted concept, reflecting the different types of receptors. The simplest are free nerve endings which detect pain and changes in temperature; slightly more complex are Merkel's tactile cells (which detect pressure); followed by Grandry bodies, which consist of two to four tactile cells and detect movement (velocity); and the lamellated Herbst corpuscles (similar to Vater-Pacinian corpuscles in mammals), which are sensitive to acceleration. — Tim Birkhead

I've told you before, Daniel: roach isn't an insult. We're the ones still standing after the mammals build their nukes, we're the ones with the stripped-down OS's so damned simple they work under almost any circumstances. We're the goddamned Kalashnikovs of thinking meat. — Peter Watts

at least some paleontologists believe that the demise
of the dinosaurs was accelerated by nocturnal predation on reptilian eggs by the early mammals. Two chicken eggs for breakfast may be all-at least on the surface-that is left of this ancient mammalian cuisine. — Carl Sagan

Shamefully, human beings are the only mammals to separate mothers from their infants. Dr. John Krystal,
Professor of Psychiatry and Neurobiology at the Yale School
of Medicine, described the impact of maternal separation on
the infant as 'profound', citing the recent discovery that the
autonomic activity (heart rate and other involuntary nervous
system activity) of two-day-old sleeping babies is 176 per
cent higher during maternal separation. — Antonella Gambotto-Burke

For their size, crows are among the brainiest organisms on Earth, outclassing not only other birds (with the possible exception of parrots), but also most mammals. — Candace Savage

And we are wild animals too, of course. We forget that. We're just mammals with attitude. In a lot of ways our skills pale before their skills, and in a lot of ways we are terrible at fitting into our environmental niche. Why we achieved this dominance is sometimes a mystery to me, and a dangerous dominance it is too. The whole point of our evolution, it seems to me, is for us to find a way to fit back into the world as it is, rather than try to remake the world to fit us, but not everybody thinks like me — Brian Doyle

If insemination were the sole biological function of sex, it could be achieved far more economically in a few seconds of mounting and insertion. Indeed, the least social of mammals mate with scarcely more ceremony. The species that have evolved long-term bonds are also, by and large, the ones that rely on elaborate courtship rituals ... Love and sex do indeed go together. — E. O. Wilson

The old age of lower mammals presents characters similar to those found in man. — Elie Metchnikoff

Animal liberationists do not separate out the human animal, so there is no rational basis for saying that a human being has special rights. A rat is a pig is a dog is a boy. They're all mammals. — Ingrid Newkirk

Dr. Peter Levine, who has worked with trauma survivors for twenty-five years, says the single most important factor he has learned in uncovering the mystery of human trauma is what happens during and after the freezing response. He describes an impala being chased by a cheetah. The second the cheetah pounces on the young impala, the animal goes limp. The impala isn't playing dead, she has "instinctively entered an altered state of consciousness, shared by all mammals when death appears imminent." (Levine and Frederick, Waking the Tiger, p. 16) The impala becomes instantly immobile. However, if the impala escapes, what she does immediately thereafter is vitally important. She shakes and quivers every part of her body, clearing the traumatic energy she has accumulated. — Marilyn Van Derbur

Before he died in 2013, the great sociologist Robert Bellah said that his view of everything he'd studied across his life was tilted on its axis by this late recognition: when mammals began to bring forth offspring from the center of their bodies, spiritual life became possible. With apes and far more with humans, the period of necessary parental care - care in order for the offspring to survive - became longer and longer. The long helplessness of the child generated a sphere of softening, experimentation, and creativity in self-understanding and shared life. This is the biological groundwork for the axial move - stepping out of fear and into care beyond one's self. The religions apprehended this long ago and wove it into language; compassion in both Hebrew and Arabic derives from the word for womb. — Krista Tippett

The notion that big business and big labor and big government can sit down around a table somewhere and work out the direction of the American economy is at complete variance with the reality of where the American economy is headed. I mean, it's like dinosaurs gathering to talk about the evolution of a new generation of mammals. — Bruce Babbitt

It would seem that marsupials are poor imitations of full-fledged mammals. Their inadequacy gives them a certain appeal; we're touched by it. — Kobo Abe

The difference between humans and other mammals is that we know how to accessorize. — Madeleine Albright

All the dinosaurs have gone off into the stars, leaving the world to mammals. — Neil Gaiman

I never sleep. Like the dolphin and the spiny anteater, I don't experience REM. Unlike the dreamless mammals, I'm a construct. I am a living program inside a vast network of electronic impulses known as the LINK. In that datastream I've uncovered the meaning of another kind of dreaming
that of a fond hope or aspiration, a yearning, a desire, or a passion. This much I have. When I dream, I dream of Mecca. — Lyda Morehouse

It's unavoidable: so long as we value money more highly than living beings and more highly than relationships, we will continue to see living beings as resources, and convert them to cash; objectifying, killing, extirpating. This is true whether we're talking about fish, fur-bearing mammals, Indians, day-laborers, and so on. If monetary value is attached to something it will be exploited until it's gone. — Derrick Jensen

I do not see the value of separating humans into a body, soul and spirit. We don't do this with any other mammals, so why do we do it with ourselves? Thinking and fresh ideas arise naturally from the rhythm of one's internal felt-sense. It is the process artists demonstrate to humanity - to express our individuality in real-time, as a living process, rather than a "copied" idea. — Christopher Zzenn Loren

Half the people I know have dead animals in their freezers: reptiles, birds, mammals. Is that normal? — David Sedaris

The order Chiroptera (the "hand-wing" creatures) encompasses 1,116 species, which amounts to 25 percent of all the recognized species of mammals. To say again: One in every four species of mammal is a bat. Such — David Quammen

Since when do politics affect a mammals ability to sustain a flame? That aside, who says a burning mouse can't run a distance of twelve feet? — David Sedaris

Brambles, in particular, protect and nourish young fruit trees, and on farms bramble clumps (blackberry or one of its related cultivars) can be used to exclude deer and cattle from newly set trees. As the trees (apple, quince, plum, citrus, fig) age, and the brambles are shaded out, hoofed animals come to eat fallen fruit, and the mature trees (7 plus years old) are sufficiently hardy to withstand browsing. Our forest ancestors may well have followed some such sequences for orchard evolution, assisted by indigenous birds and mammals. — Bill Mollison

Christians take pride in proclaiming they are sheep, the most stupid of all mammals, incapable of defending themselves, living only to feed, multiply, and be fleeced periodically. — Ralph Perier

If the germ plasm wants to swim in the ocean, it makes itself a fish; if the germ plasm wants to fly in the air, it makes itself a bird. If it wants to go to Harvard, it makes itself a man. The strangest thing of all is that the germ plasm that we carry around within us has done all those things. There was a time, hundreds of millions of years ago, when it was making fish. Then ... amphibia ... reptiles ... mammals, and now it's making men. — George Wald

Do I look like an expert in cloaked mammals? — Chris Colfer

A number of scientists now believe that somatic concordances like these are not just normal but necessary for mammals. The mammalian nervous system depends for its neurophysiologic stability on a system of interactive coordination, wherein steadiness comes from synchronization with nearby attachment figures. — Thomas Lewis

All human life on the planet is born of woman. The one unifying, incontrovertible experience shared by all women and men is that months-long period we spent unfolding inside a woman's body. Because young humans remain dependent upon nurture for a much longer period than other mammals, and because of the division of labor long established in human groups, where women not only bear and suckle but are assigned almost total responsibility for children, most of us first know both love and disappointment, power and tenderness, in the person of a woman. — Adrienne Rich

He who is not content to look, like a savage, at the phenomena of nature as disconnected, cannot any longer believe that man is the work of a separate act of creation ... Man is the co-descendant with other mammals of a common progenitor. — Charles Darwin

Why were there far more species of domesticated animals in Eurasia than in the Americas? The Americas harbor over a thousand native wild mammal species, so you might initially suppose that the Americas offered plenty of starting material for domestication. — Jared Diamond

Of all mammals, only a human being can say 'no. — Jerzy Kosinski

People travel and hunt on the sea ice - in Alaska, they hunt in skin boats for bowhead whales; in Greenland, they hunt with dogsleds. The ice is their highway. The ice is also the ecosystem in which marine mammals and terrestrial animals such as polar bears exist. — Gretel Ehrlich

Mammals of every species indulge in play. Games are Nature's way of preparing us to face difficult realities. — Daniel Suarez

that the prevalence of hierarchy is not limited to human societies. There are clear hierarchies among most social birds and mammals, including those species most nearly related to human beings. Farmers have always known that barnyard flocks of hens develop a 'pecking order' in which each hen has a rank, allowing her to peck at and drive away from food birds below her in rank, but to be pecked by, and forced to give up food to, those above her. — Anonymous

The ancestors of the higher animals must be regarded as one-celled beings, similar to the Amoebae which at the present day occur in our rivers, pools, and lakes. The incontrovertible fact that each human individual develops from an egg, which, in common with those of all animals, is a simple cell, most clearly proves that the most remote ancestors of man were primordial animals of this sort, of a form equivalent to a simple cell. When, therefore, the theory of the animal descent of man is condemned as a 'horrible, shocking, and immoral' doctrine, tho unalterable fact, which can be proved at any moment under the microscope, that the human egg is a simple cell, which is in no way different to those of other mammals, must equally be pronounced 'horrible, shocking, and immoral. — Ernst Haeckel

[L]ean start-ups are the small furry mammals competing with the large dinosaurs - meaning they're one asteroid strike away from world dominance. Exponential technology is that asteroid. — Peter H. Diamandis

If we return abruptly to a Miocene-like climate, it's reasonable to think that we would experience a lot of extinctions, and maybe even a mass extinction in the long term. Would the life on Earth be radically different? Of course we can't say for sure, but I think a lot of it would look familiar. Like a lot of people, I worry a lot about whether marine mammals would survive, especially whales. Ocean acidification is one of the major killers in climate change events, and that makes the ocean a very inhospitable place. — Annalee Newitz

If we mammals don't get something to eat every day or two, our temperature drops, all our signs fall off, and we begin to starve. Living at biological red alert, it's not surprising how obsessed we are with food; I'm just amazed we don't pace and fret about it all the time. — Diane Ackerman

If you found a mammal with feathers, then you'd know that Darwin was wrong. Well, it's rather the same with memes. — Susan Blackmore

Recently, I've ventured into the mammal family - so that's good for my sex life. — Emo Philips

There are various orders of beauty, causing men to make fools of themselves in various styles ... but there is one order of beauty which seems made to turn the heads not only of men, but of all intelligent mammals, even of women. It is a beauty like that of kittens, or very small downy ducks making gentle rippling noises with their soft bills, or babies just beginning to toddle and to engage in conscious mischief -a beauty with which you can never be angry, but that you feel ready to crush for inability to comprehend the state of mind into which it throws you. — George Eliot

Like a small business, a novel cannot afford to carry dead weight, even if it is a close family member.
It is likewise unnecessary to introduce a mother and/or father into a narrative - usually through the medium of a long telephone call on the subject of 'How's things?' - to demonstrate that the protagonist does, like all mammals, have parents. — Howard Mittelmark

Many mammals and birds have systems for strong self-control, and it is not difficult to see why such systems were advantageous and were selected for. Biding your time, deferring gratification, staying still, foregoing sex for safety, and so forth, is essential in getting food, in surviving, and in successful reproduction. — Patricia Churchland

There is a big difference between living in a society that hunts whales and living in one that views them. Nature is being reduced to precious demonstrations for entertainment and education, something far less natural than hunting. Are we headed for a world where nothing is left of nature but parks? Whales are mammals, and mammals do not lay a million eggs. We were forced to give up commercial hunting and to raise domestic mammals for meat, preserving the wild ones as best we could. It is harder to kill off fish than mammals. But after 1,000 years of hunting the Atlantic cod, we know that it can be done. — Mark Kurlansky

It is now generally accepted that the roots of our ethics lie in patterns of behavior that evolved among our pre-human ancestors, the social mammals and that we retain within our biological nature elements of these evolved responses. We have learned considerably more about this responses, and we are beginning to to understand how they interact with our capacity to reason. — Peter Singer

I am a vegetarian because I realized that even little chickens suffer pain and fear, experience a range of feelings and emotions, and are as intelligent as mammals, including dogs, cats, and even some primates. — Paul McCartney

We are mammals who need sex, need companionship, who seek the protective enclave of the family for reasons of survival and reproduction. We select a so-called loved one for the most primitive reason - my hero's preference for a pear-shaped woman is self-explanatory, I think. The loved one laughs or smells like the parent who gave one youthful succor and all else is projected, all else is invented — Robert Galbraith

This leads me to ask how it came to be that Pluto is Mickey's dog, but Mickey is not Pluto's mouse. Something is awry in the taxonomic class of mammals in the Disney universe. I — Neil DeGrasse Tyson

And it's deadly to us. We can inspire lust, but it's just a shadow. An illusion. Love is a dangerous force." He shook his head. "Love killed the dinosaurs, man."
I'm pretty sure a meteor killed the dinosaurs, Thomas."
He shrugged. "There's a theory making the rounds now that when the meteor hit it only killed off the big stuff. That there were plenty of smaller reptiles running around, about the same size as all the mammals at the time. The reptiles should have regained their position eventually, but they didn't, because the mammals could feel love. They could be utterly, even irrationally devoted to their mates and their offspring. It made them more likely to survive. The lizards couldn't do that. The meteor hit gave the mammals their shot, but it was love that turned the tide. — Jim Butcher

The civilized people of today look back with horror at their medieval ancestors who wantonly destroyed great works of art or sat slothfully by while they destroyed. We have passed this stage ... Here in the U.S. we turn our rivers and streams into sewers and dumping grounds, we pollute the air, we destroy our forests and exterminate fishes, birds and mammals - not to speak of vulgarizing charming landscapes with hideous advertisements. But at best it looks as if our people were awakening. — Theodore Roosevelt

Dolphins are social mammals, capable of enjoying their lives. They form close bonds with other members of their group. — Peter Singer

Perhaps no order of mammals presents us with so extraordinary a series of gradations as this [step by step, from humans to apes to monkeys to lemurs] - leading us insensibly from the crown and summit of the animal creation down to creatures, from which there is but a step, as it seems, to the lowest, smallest, and least intelligent of the placental Mammalia. It is as if nature herself had forseen the arrogance of man, and with Roman severity had provided that his intellect, by its very triumphs, should call into prominence the slaves, admonishing the conqueror that he is but dust. — Thomas Huxley

As llamas have never heard of oxygen, they do not miss it. — Will Cuppy

But civilized human beings are alarmingly ignorant of the fact that they are continuous with their natural surroundings. It is as necessary to have air, water, plants, insects, birds, fish, and mammals as it is to have brains, hearts, lungs, and stomachs. The former are our external organs in the same way that the latter are our internal organs. If then, we can no more live without the things outside than without those inside, the plain inference is that the words "I" and "myself " must include both sides. The sun, the earth, and the forests are just as much features of your own body as your brain. Erosion of the soil is as much a personal disease as leprosy, and many "growing communities" are as disastrous as cancer. — Alan W. Watts

(However, animals apparently dream differently than we do. In the dolphin, for example, only one hemisphere at a time sleeps in order to prevent drowning, because they are air-breathing mammals, not fish. So if they dream, it is probably in only one hemisphere at a time.) — Michio Kaku

There are transitional forms between the metals and non-metals; between chemical combinations and simple mixtures, between animals and plants, between phanerogams and cryptogams, and between mammals and birds [ ... ]. The improbability may henceforth be taken for granted of finding in Nature a sharp cleavage between all that is masculine on the one side and all that is feminine on the other; or that any living being is so simple in this respect that it can be put wholly on one side, or wholly on the other, of the line. — Otto Weininger

Consciousness," according to current scientific thought, was something the higher mammals had evolved in order to help them reproduce, much the way a garden slug secretes slime. It had no special ontological status. The "self" was a genetically modulated and biologically useful illusion. — Robert Charles Wilson

Around the world, about a thousand dolphins are held in captivity, while millions have been killed in purse seine tuna nets and drift nets. Tens of thousands of others have been "sacrificed" in the name of scientific research, some marine mammals merely to find out what they've been eating. — Richard O'Barry

Man is a sad mammal that combs its hair. — Cees Nooteboom

The picture's pretty bleak, gentlemen ... The world's climates are changing, the mammals are taking over, and we all have a brain about the size of a walnut. — Gary Larson

dolphins are not the benevolent mammals we'd like them to be; those beaming faces hide the minds of assassins. — Philip Hoare

Thanks to this availability of suitable wild mammals and plants, early peoples of the Fertile Crescent could quickly assemble a potent and balanced biological package for intensive food production. That package comprised three cereals, as the main carbohydrate sources; four pulses, with 20 - 25 percent protein, and four domestic animals, as the main protein sources, supplemented by the generous protein content of wheat; and flax as a source of fiber and oil (termed linseed oil: flax seeds are about 40 percent oil). Eventually, thousands of years after the beginnings of animal domestication and food production, the animals also began to be used for milk, wool, plowing, and transport. Thus, the crops and animals of the Fertile Crescent's first farmers came to meet humanity's basic economic needs: carbohydrate, protein, fat, clothing, traction, and transport. — Jared Diamond

People are talking about immigration, emigration and the rest of the fucking thing. It's all fucking crap. We're all human beings, we're all mammals, we're all rocks, plants, rivers. Fucking borders are just such a pain in the fucking arse. — Shane MacGowan

Faith is the surrender of the mind, it's the surrender of reason, it's the surrender of the only thing that makes us different from other animals. It's our need to believe and to surrender our skepticism and our reason, our yearning to discard that and put all our trust or faith in someone or something, that is the sinister thing to me ... Out of all the virtues, all the supposed virtues, faith must be the most overrated — Christopher Hitchens

It only takes twenty generations of selective breeding to create large differences or appearance and behavior in other mammals. — Jonathan Haidt

In this way a process of evolution was started that led to the development of more and more complicated, self-reproducing organisms. The first primitive forms of life consumed various materials, including hydrogen sulfide, and released oxygen. This gradually changed the atmosphere to the composition that it has today, and allowed the development of higher forms of life such as fish, reptiles, mammals, and ultimately the human race. — Stephen Hawking

The woods were full of sound: the stream between the rocks, the wind among the needles of the pine branches, the chitter of insects and the cries of small arboreal mammals, as well as the birdsong; and from time to time a stronger gust of wind would make one of the branches of a cedar or a fir move against another and groan like a cello. It — Philip Pullman

There is part of a structure in which every species is related to every other species. And they're built up on species, like a pyramid. The simpler cell organisms, and then the more complicated ones, all the way up to the mammals and birds and so forth. We call it 'developing upward' ... The whole thing depends on every part of it. And we're taking out the stones from the pyramid. — W.S. Merwin

In the superman Nietzsche gave the world a conceivable and possible goal for all human effort. But there still remained a problem and it was this: When the superman at last appears on earth, what then? Will there be another super-superman to follow and another super-super-superman after that? In the end, will man become the equal of the creator of the universe, whoever or whatever He may be? Or will a period of decline come after, with return down the long line, through the superman down to man again, and then on to the anthropoid ape, to the lower mammals, to the asexual cell, and, finally, to mere inert matter, gas, ether, and empty space? — H.L. Mencken

But human borders mean nothing to air, water, windblown soil or seeds or migrating fish, birds or mammals. — David Suzuki

We belong to that order of mammals, the primates, distinguished by its propensity for repeated single litters, intense parental care, long life-spans, late sexual maturity, and a complex and extensive social existence ... Our protracted biological and psychological helplessness, which extends well into the third year of life, intensifies the bond between infant and parents, making possible a sense of generational continuity. In contrast to other primates these bonds are not obliterated after sexual maturity. — Louise J. Kaplan

Warm-bloodedness is one of the key factors that have enabled mammals to conquer the Earth, and to develop the most complex bodies in the animal kingdom. In this series, we will travel the world to discover just how varied and how astonishing mammals are. — David Attenborough

I feel strangely selfish to say that I am saddened that one of my favourite land mammals the rough Lemurs will be extinct soon. I guess with the loving weights of human endeavour it should just be expected and then we can all label yet another extinction as progress ... — Steve Merrick

We are medium-sized mammals who only prosper because we've developed a half-arsed ability to terraform the less suitable bits of the planet we evolved on, and we're conscious of our inevitable decay and death, and we can't live anywhere else. There is no invisible sky daddy to give us immortal life and a harp and wings when we die. — Charles Stross

There is a relative order to the fossilized species of plants found in the geologic record for which Flood Geology cannot account, unless you can imagine apple and orange trees with Nike sneakers on their roots, racing past the magnolias and primitive mammals, leaving the ginkgoes back there with the dinosaurs when the Flood waters began to rise. — Frank Zindler

Like other mammals, they are capable of strong emotions. They have certainly committed no crimes. I do not claim to have the answer, but I think it is
certainly worthwhile to raise the question: Why, exactly, all over the civilized world, in virtually every major city, are apes in prison? — Carl Sagan

Apparently being a mermaid is dead dull. I watched The Little Mermaid with her once a few years ago - she thought it was freaking hilarious. She couldn't stop laughing about the shell-bra thing, given that mermaids aren't mammals. Plus, as she put it, Prince Eric was far too hairy and "peach colored" for her taste. I always thought he was pretty hot, but then again, I am a mammal. — Kiersten White

Now the leatherback turtle overcame the heat issue via a simple, but evolutionarily impossible solution; it is the only reptile that possesses fatty insulation known as brown adipose tissue, and the only reptile that regulates a high body temperature. This brown adipose tissue is the expression of the UCP1 gene, and, aside from the leatherbacks, is found only in mammals, amphibians, and fishes. Not one other reptile has UCP1. — B.C. Chase

Scientists have detected about 100 imprinted genes in mice, and about half this number in humans. It's not clear if there are genuinely fewer imprinted genes in humans than in mice, or if it's just more difficult to detect them experimentally. Imprinting evolved about 150 million years ago7, and it really only occurs to a great extent in placental mammals. It isn't found in those classes that can reproduce parthenogenetically. — Nessa Carey

It's very likely that most mammals have consciousness, and probably birds, too. — Richard Dawkins

We may have charted all the continents on the planet, and we may have discovered all the mammals, but that doesn't mean that there's nothing left to explore on Earth. — Nathan Wolfe

I think midwifery was developed by people with common sense, people who were close to nature, and people who observed other species of mammals and saw that there were lessons there to be learned. — Ina May Gaskin

If the second dinosaur to the left of the tall cycad tree had not happened to sneeze and thereby fail to catch the tiny, shrew-like ancestor of all the mammals, we should none of us be here. — Richard Dawkins

Evolution has made Homo sapiens, like other social mammals, a xenophobic creature. Sapiens instinctively divide humanity into two parts, 'we' and 'they'. — Yuval Noah Harari

Cat saliva contains a natural deodorant which is why they lick themselves a lot. It's been proven by zoologists that cats that lick the smell off themselves survive longer and have more successful offspring. It's also their way of hiding themselves from predators like large snakes, lizards and other larger carnivorous mammals. — James Bowen

Microbes are invisible to our naked eye, with a few exceptions that reinforce the rule. Millions can fit into the eye of a needle. But if you were to gather them all up, not only would they outnumber all the mice, whales, humans, birds, insects, worms, and trees combined - indeed all of the visible life-forms we are familiar with on Earth - they would outweigh them as well. Think about that for a moment. Invisible microbes comprise the sheer bulk of the Earth's biomass, more than the mammals and reptiles, all the fish in the sea, the forests. — Martin J. Blaser

We know virtually all of the genes known to mammals. We do not know all of the combinations. — Craig Venter

Livestock adopted in Africa were Eurasian species that came in from the north. Africa's long axis, like that of the Americas, is north/south rather than east/west. Those Eurasian domestic mammals spread southward very slowly in Africa, because they had to adapt to different climate zones and different animal diseases. — Jared Diamond

In a relationship, one mind revises another; one heart changes its partner. This astounding legacy of our combined status as mammals and neural beings is limbic revision: the power to remodel the emotional parts of the people we love, as our Attractors activate certain limbic pathways, and the brain's inexorable memory mechanism reinforces them. Who we are and who we become depends, in part, on whom we love. — Thomas Lewis

Where else is fatness at a premium? The answer is clear. There are two classes of mammals which are liable to accumulate large quantities of adipose tissue - hibernating mammals and aquatic mammals. — Elaine Morgan

The cause of these great extinctions, the most extensive in the seventy-million-year record for mammals, is a mystery. The two prevailing guesses, climatic environmental pressure or the destruction caused by human immigration in these regions, are at a stalemate. Nearly all regions of extinction were briefly inhabited by early humans, which is why some feel they played roles. I was not there at the time, so I can only speculate, but surely a global catastrophe of some sort triggered the cataclysm. — Stephen J. O'Brien
