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

Irreducible complexity is a problem for Darwinian evolution. Whenever we see these complex functional systems we realise that they have to be designed.

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

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

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.

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.

Despite some remaining puzzles, there's no reason to doubt that Darwin had this point right, that all creatures on earth are biological relatives
