Genetic Evidence Quotes

It has yet to be shown by direct biochemical methods, as opposed to the indirect genetic evidence mentioned earlier, that the code is indeed a triplet code.

What if I told you every single person in America - every single person on Earth - is African? With a small scrape of cells from the inside of anyone's cheek, the science of genetics can even prove it.

We don't need fossils - the case for evolution is watertight without them; so it is paradoxical to use gaps in the fossil record as though they were evidence against evolution

For example, both humans and chimps have a broken copy of a gene that in other mammals helps make vitamin C. ... It's hard to imagine how there could be stronger evidence for common ancestry of chimps and humans. ... Despite some remaining puzzles, there's no reason to doubt that Darwin had this point right, that all creatures on earth are biological relatives.

Only a tiny fraction of corpses fossilize, and we are lucky to have as many intermediate fossils as we do. We could easily have had no fossils at all, and still the evidence for evolution from other sources, such as molecular genetics and geographical distribution, would be overwhelmingly strong. On the other hand, evolution makes the strong prediction that if a single fossil turned up in the wrong geological stratum, the theory would be blown out of the water.

Very close cousins like humans and chimps have almost all their genes in common. Slightly less close cousins like humans and monkeys still have recognizably the same genes. You could carry on right on down to humans and bacteria, and you will find continuous compelling evidence for the hierarchical tree of cousinship.

Some racists still reject the plain testimony written in the DNA that all the races are not only human but nearly indistinguishable. . . .

Molecular genetics can show off some surprising relationships like, for example, the close relationship of whales to hippopotamuses, which I think nobody ever guessed until molecular data was looked at. The closest relatives of whales are hippopotamuses, even closer than any other cloven-hoofed animals.

Taken with the archaeological data, we can say that the old hypothesis of an invasion of people - not merely their language - from the steppe appears to be true.

The arrival of DNA testing has brought new dimensions to the investigation of crime. It has brought resolution to old cases where past investigators were unable to uncover the truth. It has brought justice in new cases where once the truth might never have been known.
