Common Ancestor Quotes & Sayings

Biochemists assume that the three cellular kingdoms evolved from a single common ancestor, because the alternative of supposing an independent origin of life two or more times presents still greater difficulties. The common ancestor is merely hypothetical, as are the numerous transitional intermediate forms that would have to connect such enormously different groups to the ancestor. From a Darwinist viewpoint all these hypothetical creatures are a logical necessity, but there is no empirical confirmation that they existed. — Phillip E. Johnson

An irrefutable proof that such single-celled primaeval animals really existed as the direct ancestors of Man, is furnished according to the fundamental law of biogeny by the fact that the human egg is nothing more than a simple cell. — Ernst Haeckel

Molecular evidense suggests that our common ancestor with the chimpanzees lived, in Africa, between 5 and 7 million years ago, say half a million generations ago. This is not long by evolutionary standards. — Richard Dawkins

Religion and science have a common ancestor - ignorance. — A.C. Grayling

Every human alive today came from a single mother in Africa, who lived about two hundred thousand years ago. Later, when the sea levels receded about ninety thousand years ago, a small tribe of a few hundred traveled out of the plains of Africa. After crossing the Red Sea through the Gate of Grief passageway, they fanned out and populated the entire world. How can there be any strangers among us when we all share a single common ancestor? — Nina Wirk

All modern humans are related to what scientists call "Mitochondrial Eve." This refers to our common matrilineal ancestor. She lived approximately 200,000 years ago and depending on how you estimate the length of a generation, we are only 5,000 to 10,000 generations from one another. To put it another way, each of us is a cousin of one another at most 10,000 times removed. And yes, Mitochondrial Eve lived in Africa, so, in a very real way, we are all Africans. — Desmond Tutu

When two strangers in a tribal society want to trade, they will often establish trust by appealing to a common god, mythical ancestor or totem animal. — Yuval Noah Harari

An oak tree and I are made of the same stuff. If you go far enough back, we have a common ancestor. The — Carl Sagan

If you share a common ancestor with somebody, you're related to them. It doesn't mean that you're going to invite them to the family reunion, but it means that you share DNA. I think it's fascinating. — Henry Louis Gates

All of today's DNA, strung through all the cells of the earth, is simply an extension and elaboration of [the] first molecule. — Lewis Thomas

I've noticed a fascinating phenomenon in my thirty years of teaching: schools and schooling are increasingly irrelevant to the great enterprises of the planet. No one believes anymore that scientists are trained in science classes or politicians in civics classes or poets in English classes. The truth is that schools don't really teach anything except how to obey orders. This is a great mystery to me because thousands of humane, caring people work in schools as teachers and aides and administrators, but the abstract logic of the institution overwhelms their individual contributions. Although teachers to care and do work very, very hard, the institution is psychopathic
it has no conscience. It rings a bell and the young man in the middle of writing a poem must close his notebook and move to a different cell where he must memorize that humans and monkeys derive from a common ancestor. — John Taylor Gatto

Then, of course, through the umbilical link we all tumble backwards down the spiralling DNA staircase to one common ancestor in Africa, and before that some bunch of curious monkeys. Down and down we go unto the sea, unto the dust, the single cellular dust. What impulse drove one cell to become two? What yearning pulled the fish on to the land? What caused apes to walk upright? Some invisible magnetic pull. Is there a difference between attraction and intention? Where is evolution taking us? — Russell Brand

Hamilton had a complaint. "Why did you have to tell the cops I'm your boyfriend? That's gross, Amy. We're related!"
Amy was disgusted. "We had a common ancestor, like, five hundred years ago. Besides, if they think we're together, we only have to come up with one story, and I can do all the talking."
"Hey, I got an early acceptance to Notre Dame," Hamilton said defensively. "I can talk."
"Of course you can," Amy soothed. "It's what you say that might get us into trouble. — Gordon Korman

Homo sapiens who lived in caves put trash in front and slept in the back; not so in the caves occupied by Homo heidelbergensis. Those humans, probably the last common ancestor of Homo sapiens and neanderthalensis, lived like frat boys 700,000 to 300,000 years ago, "flinging shit everywhere" - and the idea of slovenly boy and girl ancestors fascinated me. "Big heavy stone tools . . . probably solved things with brute force. Commandos without too much thought," Shea riffed. "If you were going to cast Jersey Shore, you'd go with heidelbergensis. — Marilyn Johnson

The uniformity of the earth's life, more astonishing than its diversity, is accountable by the high probability that we derived, originally, from some single cell, fertilized in a bolt of lightning as the earth cooled. It is from the progeny of this parent cell that we take our looks; we still share genes around, and the resemblance of the enzymes of grasses to those of whales is a family resemblance. — Lewis Thomas

By comparing the human and chimp genomes, we can see the process of evolution clearly in the changes (in DNA) since we diverged from our common ancestor. — Bob Waterston

Yes, evolution by descent from a common ancestor is clearly true. If there was any lingering doubt about the evidence from the fossil record, the study of DNA provides the strongest possible proof of our relatedness to all other living things. — Francis Collins

Searching for alternative life on Earth might seem misconceived, because there is excellent evidence that every kind of life so far studied evolved from a common ancestor that lived billions of years ago. Yet most of the life that exists on Earth has never been properly classified. — Paul Davies

The common ancient ancestor of mulluses and chordates could not possibly have possessed a camera eye, so quite clearly they have evolved independently. The solution has been arrived at by completely different routes. — Simon Conway Morris

If a single cell, under appropriate conditions, becomes a man in the space of a few years, there can surely be no difficulty in understanding how, under appropriate conditions, a cell may, in the course of untold millions of years, give origin to the human race. — Herbert Spencer

The stuff of which the world of our experience is composed is, in my belief, neither mind nor matter, but something more primitive than either. Both mind and matter seem to be composite, and the stuff of which they are compounded lies in a sense between the two, in a sense above them both, like a common ancestor. — Bertrand Russell

We split from our common ancestor with the octopus half a billion years ago. And yet, you can make friends with an octopus. — Sy Montgomery

As commonly understood, creationism involves belief in an earth formed only about ten thousand years ago, an interpretation of the Bible that is still very popular. For the record, I have no reason to doubt that the universe is the billions of years old that physicists say it is. Further, I find the idea of common descent (that all organisms share a common ancestor) fairly convincing, and have no particular reason to doubt it. — Michael Behe

And, you know, the fact is, if you believe in evolution, we all have a common ancestor, and we all have a common ancestry with the plant in the lobby. This is what evolution tells us. And, it's true. It's kind of unbelievable. — Jeff Hawkins

In our evolutionary history some individuals must have been born with a greater inclination and ability to collaborate than our common ancestor with chimpanzees. These individuals were more successful and bred more offspring with those characteristics [...]. What we have evolved into now is a species for whom an experience means little if it's not shared. — Christine Kenneally

The many meanings of 'evolution' are frequently exploited by Darwinists to distract their critics. Eugenie Scott recommends: 'Define evolution as an issue of the history of the planet: as the way we try to understand change through time. The present is different from the past. Evolution happened, there is no debate within science as to whether it happened, and so on ... I have used this approach at the college level.'
Of course, no college student - indeed, no grade-school dropout - doubts that 'the present is different from the past.' Once Scott gets them nodding in agreement, she gradually introduces them to 'The Big Idea' that all species - including monkeys and humans - are related through descent from a common ancestor ... This tactic is called 'equivocation' - changing the meaning of a term in the middle of an argument. — Jonathan Wells

We observe closely related species in sympatry and infer how they evolved from a common ancestor. — Peter R. Grant

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

We share a common ancestor with chimps that is not shared by mandrills, we share a common ancestor with mandrills that is not shared by bushbabies, and on and on and on, to the ancestor we share with nematode worms that is not shared with oak trees. — Simon Barnes

The different human peoples did not evolve out of a common ancestor; they were each born out of the womb of their own homeland. We appeared in different parts of the world at the same time. Each group was as much a part of their environment as the other animals and plants of the region. — Eliot Cowan

Most curious is the way that Y/surname patterns differ between countries. In Britain, on average, a man who has the same surname as another is significantly more likely to have a similar Y chromosome, and therefore a common ancestor, than he would with someone of a different surname. But there's a twist: The Y similarity depends on the frequency of the surname within the population. If you are a Smith, for example, the rule does not apply. — Christine Kenneally

If we go far enough back, any two people on Earth have a common ancestor. — Carl Sagan

We are all a complete mixture;yet at the same time,we are all related.Each gene can trace its own journey to a different common ancestor.This is a quite extraordinary legacy that we all have inherited from the people who lived before us.Our genes did not just appear when we were born.They have been carried to us by millions of individual lives over thousands of generations. — Bryan Sykes

What is a totem? It is as a rule an animal (whether edible and harmless or dangerous and feared) and more rarely a plant or a natural phenomenon (such as rain or water), which stands in a peculiar relation to the whole clan. In the first place, the totem is the common ancestor of the clan; at the same time it is their guardian spirit and helper, which sends them oracles and, if dangerous to others, recognizes and spares its own children. — Sigmund Freud

A friend of ours has a hobby doing genealogy, and we found out that we were cousins in the ninth degree, that we had a common ancestor on the Mayflower. — Marion Zimmer Bradley
