The evidence for evolution pours in, not only from geology, paleontology, biogeography, and anatomy, but of course from molecular biology and every other branch of the life sciences.
On the ordinary view of each species having been independently created, we gain no scientific explanation.
In the theory of evolution there is no talk of God and no Bibles are used. They're not looking for higher powers, extraterrestrials, or anything else that could be found in the science fiction section, because they are not dealing with fiction.
Charles Darwin and I and you broke off from the family tree from chimpanzees about five million years ago. They're still our closest genetic kin. We share 98.8 percent of the genes. We share more genes with them than zebras do with horses. And we're also their closest cousin. They have more genetic relation to us than to gorillas.
In fact, nothing in science as a whole has been more firmly established by interwoven factual information, or more illuminating than the universal occurrence of biological evolution. Further, few natural processes have been more convincingly explained than evolution by the theory of natural selection, or as it has been popularly called, Darwinism.
Life is a copiously branching bush, continually pruned by the grim reaper of extinction, not a ladder of predictable progress.
When discussing organic evolution the only point of agreement seems to be: ‘It happened.’ Thereafter, there is little consensus, which at first sight must seem rather odd.
I believe the evidence strongly supports common descent. But the root question remains unanswered: What has caused complex systems to form?
The story of evolution unfolds with increasing levels of abstraction.
I have a standing offer of $250,000 to anyone who can give any empirical evidence (scientific proof) for evolution. My $250,000 offer demonstrates that the hypothesis of evolution is nothing more than a religious belief.
Despite some remaining puzzles, there's no reason to doubt that Darwin had this point right, that all creatures on earth are biological relatives
Evolutionary biology is crazy because sometimes it seems anybody can draw any conclusion they want.
Fragments of the natural method must be sought with the greatest care. This is the first and last desideratum among botanists. Nature makes no jumps. [Natura non facit saltus] All taxa show relationships on all sides like the countries on a map of the world.
We observe closely related species in sympatry and infer how they evolved from a common ancestor.
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
You might recognize me, I'm the fourth guy from the left on the evolutionary chart.
When students of other sciences ask us what is now currently believed about the origin of species, we have no clear answer to give. Faith has given way to agnosticism. Meanwhile, though our faith in evolution stands unshaken we have no acceptable account of the origin of species.
Man's Place in Nature.
Why, if species have descended from other species by insensibly fine gradations, do we not everywhere see innumerable transitional forms.
I find the idea of common descent (that all organisms share a common ancestor) fairly convincing, and have no particular reason to doubt it.
Within the period of human history we do not know of a single instance of the transformation of one species into another one. It may be claimed that the theory of descent is lacking, therefore, in the most essential feature that it needs to place the theory on a scientific basis, this must be admitted.
Splitting and gradual divergence of genera is exemplified very well and in a large variety of organisms.
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.
If you go far enough back, your genome connects you with bacteria, butterflies, and barracuda - the great chain of being linked together through DNA.
Most of the tree of life is effectively arranged.
