My brother-in-law pointed me to this article on one species (soon to be 2!) whose evolution has been influenced by humans. This study looks at birds who have begun wintering in England, due to the prevalence of bird feeders providing food, and whose evolutionary path has altered because of it. Nifty!
Coming soon, as soon as I get the book back from the library - review of Denis Alexander's "Creation or Evolution: Do we have to choose?" I read it a month or so ago and meant to post, but never did. Excellent book!
