This page provides some links to a few of my essays about evolution.
Before moving on, let me nail my colours to the mast immediately:
That’s all I’m going to say about that. From here on in, we shall discuss evolution.
Living things are observed to change in important and sometimes fundamental ways over the course of many generations. If all we are seeking is a definition for a word, then ‘descent with modification’ is it.
But a deeper understanding must at least attempt to account for the detailed patterns of change observed on all timescales, including the very long timescale of the fossil record, to provide a mechanism for such change, and explain how and why it works. Charles Darwin (1809-1882) achieved this, when he explained natural selection. Today, nobody (well, nobody serious) doubts that evolution by natural selection occurs; it is the unifying theory of all biology. In the famous words of Theodosius Dobzhansky, “nothing in biology makes sense except in the light of evolution” (1973). There are some who maintain that natural selection is not the only mechanism operating, and there are debates about the importance of saltation and so on, though in my mind these are mostly empty or, at best, the deeply muddled results of semantic confusion.
