I find the idea of common descent (that all organisms share a common ancestor) fairly convincing, and have no particular reason to doubt it.

The question is: exactly how did life get here? Was it by natural selection and random mutation or was it by something else? Everybody - even Richard Dawkins - sees design in biology. You see this design when you see co-ordinated parts coming together to perform a function - like in a hand. And so it's the appearance of design that everybody's trying to explain. So that if Darwin's theory doesn't explain it we're left with no other explanation than maybe it really was designed. That's essentially the design argument.

Thus it seemed to Haeckel that such simple life could easily be produced from inanimate material.

It was only about sixty years ago that the expansion of the universe was first observed.

It was a shock to people of the nineteenth century when they discovered, from observations science had made, that many features of the biological world could be ascribed to the elegant principle of natural selection.

The trap does not work until all the parts were there. The system itself doesn't work until you fit all of them together.

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