Throughout history there have been many other examples, similar to that of Haeckel, Huxley and the cell, where a key piece of a particular scientific puzzle was beyond the understanding of the age.

Science is not a game in which arbitrary rules are used to decide what explanations are to be permitted.

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

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

It is often said that science must avoid any conclusions which smack of the supernatural.

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

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