Genera Quotes & Sayings

As the species of the same genus usually have, though by no means invariably, much similarity in habits and constitution, and always in structure, the struggle will generally be more severe between them, if they come into competition with each other, than between the species of distinct genera. — Charles Darwin

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

Splitting and gradual divergence of genera is exemplified very well and in a large variety of organisms. — George Gaylord Simpson

People began to understand that with the acquisition of California the nation had obtained practically half a continent, of which the future possibilities were almost unlimited, so far as the development of natural resources and the genera production of wealth were concerned. — John Moody

Let us suppose that we have laid on the table ... [a] piece of glass ... and let us homologize this glass to a whole order of plants or birds. Let us hit this glass a blow in such a manner as but to crack it up. The sectors circumscribed by cracks following the first blow may here be understood to represent families. Continuing, we may crack the glass into genera, species and subspecies to the point of finally having the upper right hand corner a piece about 4 inches square representing a sub-species. — Leon Croizat

I don't tend to set out on huge world domination goals or have anything in mind. I just like to play. I like to gig a lot; I like to write music. — Imelda May

The close relationship between railroad expansion and the genera development and prosperity of the country is nowhere brought more distinctly into relief than in connection with the construction of the Pacific railroads. — John Moody

Every paleontologist knows that most new species, genera, and families, and that nearly all categories above the level of family appear in the record suddenly and are not led up to by known, gradual, completely continuous transitional sequences. — George Gaylord Simpson

Among the authorities it is generally agreed that the Earth is at rest in the middle of the universe, and they regard it as inconceivable and even ridiculous to hold the opposite opinion. However, if we consider it more closely the question will be seen to be still unsettled, and so decidedly not to be despised. For every apparent change in respect of position is due to motion of the object observed, or of the observer, or indeed to an unequal change of both. — Nicolaus Copernicus

The idea that one can go to the fossil record and expect to empirically recover an ancestor-descendant sequence, be it of species, genera, families, or whatever, has been, and continues to be, a pernicious illusion. — Gareth J. Nelson

If you're getting your guidance about who you are and what to do with your life only from the external world, then by definition you'll be led away from your authentic truth. Your authentic truth isn't in the material world. It's counterintuitive, but you have more power in the world when you know you're not of it. — Marianne Williamson

The chemical differences among various species and genera of animals and plants are certainly as significant for the history of their origins as the differences in form. If we could define clearly the differences in molecular constitution and functions of different kinds of organisms, there would be possible a more illuminating and deeper understanding of question of the evolutionary reactions of organisms than could ever be expected from morphological considerations. — Ray Lankester

God is not related to creatures as though belonging to a different "genus," but as transcending every "genus," and as the principle of all "genera. — Thomas Aquinas

Unless mankind redesigns itself by changing our DNA through altering our genetic makeup, computer-genera ted robots will take over our world. — Stephen Hawking

Oceans need more attention because climate change IS an ocean issue. Our oceans will be the first victim, and sea life will suffer dramatically. Detailed proof is hard in ocean science, but I think we're already seeing big ocean changes caused by climate change, such as starvation of whales, seabirds, and other animals off the coast US west coast. — Mark Powell

I am fully convinced that species are not immutable; but that those belonging to what are called the same genera are lineal descendants of some other and generally extinct species, in the same manner as the acknowledged varieties of any one species are the descendants of that species. Furthermore, I am convinced that natural selection has been the most important, but not the exclusive, means of modification. — Charles Darwin

I think how this is always the way he is, giving me something even when most would think there was nothing left to do but let go — Ally Condie

The names of the plants ought to be stable [certa], consequently they should be given to stable genera. — Carl Linnaeus

At the time of the Cognitive Revolution, the planet was home to about 200 genera of large terrestrial mammals weighing over 100 pounds. At the time of the Agricultural Revolution, only about a hundred remained. Homo sapiens drove to extinction about half of the planet's big beasts long before humans invented the wheel, writing, or iron tools. — Yuval Noah Harari

If about a dozen genera of birds had become extinct or were unknown, who would have ventured to have surmised that birds might have existed which used their wings solely as flappers, like the logger-headed duck (Micropterus of Eyton); as fins in the water and front legs on the land, like the penguin; as sails, like the ostrich; and functionally for no purpose, like the Apteryx. Yet the structure of each of these birds is good for it, under the conditions of life to which it is exposed, for each has to live by a struggle; but it is not necessarily the best possible under all possible conditions. It must not be inferred from these remarks that any of the grades of wing-structure here alluded to, which perhaps may all have resulted from disuse, indicate the natural steps by which birds have acquired their perfect power of flight; but they serve, at least, to show what diversified means of transition are possible. — Charles Darwin

Ignorance produced genera, and science produced, and will continue to produce, proper names; nor of these shall we be afraid to increase the number, whenever we shall have occasion to denote different species. — Georges-Louis Leclerc, Comte De Buffon

Universitas in modo citharae sit disposita, in qua diversa genera in modo chordarum sit consonantia. The universe is arranged like a cithera, in which different kinds of things sound together harmoniously, just as they do in a chord. — Honorius Augustodunensis

Established species are evolving so slowly that major transitions between genera and higher taxa must be occurring within small rapidly evolving populations that leave NO LEGIBLE FOSSIL RECORD. — Steven M. Stanley

Anglers may be divided into almost as many genera and species as the fish they catch, and engage in the sport from as many impulses. — Thaddeus Norris

I perceive that they are good and beautiful, that they exist according to their own rules of proportion, that they differ in genus and species from all other genera and species, that they are defined by their own number, that they are true to their order, that they seek their specific place according to their weight. — Umberto Eco

Your dynamic with Peeta, thereby affecting the mood in the districts," he says. "It will be the same on the tour. I'll be in love with him just as I was," I say. "Just as you are," corrects President Snow. "Just as I am," I confirm. "Only you'll have to do even better if the uprisings are to be averted," he says. "This tour will be your only chance to turn things around." "I know. I will. I'll convince everyone in the districts that I wasn't defying the Capitol, that I was crazy with love," I say. President — Suzanne Collins

Whatever may be the experience in everyday life, the basci inner Truth should not be forgotten. — Sathya Sai Baba

The air of caricature never fails to show itself in the products of reason applied relentlessly and without correction. The observation of clinical facts would seem to be a pursuit of the physician as harmless as it is indispensable. [But] it seemed irresistibly rational to certain minds that diseases should be as fully classifiable as are beetles and butterflies. This doctrine ... bore perhaps its richest fruit in the hands of Boissier de Sauvauges. In his Nosologia Methodica published in 1768 ... this Linnaeus of the bedside grouped diseases into ten classes, 295 genera, and 2400 species. — Wilfred Trotter

We admit as many genera as there are different groups of natural species of which the fructification has the same structure. — Carl Linnaeus

Is it philosophical, is it quite allowable, to assume without evidence from fossil plants that the family or any of the genera was once larger and wide spread? and occupied a continuous area? — Asa Gray

I'm a big yachting fan. — David Cunliffe

INDECISION, n. The chief element of success; "for whereas," saith Sir Thomas Brewbold, "there is but one way to do nothing and divers way to do something, whereof, to a surety, only one is the right way, it followeth that he who from indecision standeth still hath not so many chances of going astray as he who pusheth forwards"
a most clear and satisfactory exposition on the matter.
"Your prompt decision to attack," said Genera Grant on a certain occasion to General Gordon Granger, "was admirable; you had but five minutes to make up your mind in."
"Yes, sir," answered the victorious subordinate, "it is a great thing to be know exactly what to do in an emergency. When in doubt whether to attack or retreat I never hesitate a moment
I toss us a copper."
"Do you mean to say that's what you did this time?"
"Yes, General; but for Heaven's sake don't reprimand me: I disobeyed the coin. — Ambrose Bierce

Branches or types are characterized by the plan of their structure,
Classes, by the manner in which that plan is executed, as far as ways and means are concerned,
Orders, by the degrees of complication of that structure,
Families, by their form, as far as determined by structure,
Genera, by the details of the execution in special parts, and
Species, by the relations of individuals to one another and to the world in which they live, as well as by the proportions of their parts, their ornamentation, etc. — Louis Agassiz

I accept extinction as best explaining disjoined species. I see that the same cause must have reduced many species of great range to small, and that it may have reduced large genera to so small, and of families. — Asa Gray
