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.

I believe the evidence strongly supports common descent. But the root question remains unanswered: What has caused complex systems to form?

The conclusion of design flows naturally from the data; we should not shrink from it; we should embrace it and build on it.

In the 19th century the anatomy of the eye was known in great detail and the sophisticated mechanisms it employs to deliver an accurate picture of the outside world astounded everyone who was familiar with them.

Although Darwin was able to persuade much of the world that a modern eye could be produced gradually from a much simpler structure, he did not even attempt to explain how the simple light sensitive spot that was his starting point actually worked.

The basic structure of proteins is quite simple: they are formed by hooking together in a chain discrete subunits called amino acids.

The theory of undirected evolution is already dead, but the work of science continues.
