Scientists bend observation to fit evolution

This is another archival repost, originally posted on the old blog in feb 2009, during the Darwin 200 celebrations. I wrote the majority of this post a couple of years ago, when I had the intention to do a regular “creationist claim” feature, but for some reason never got around […]


The selfish gene drives an operon

This is another archival repost first written for the old blog in 2007. On Monday I mentioned John Maynard Smith’s videos at People’s Archive. They really are marvelous, and you should watch them all. One of the topics he discusses is horizontal gene transfer in bacteria, a subject I discussed […]


Risk compensation, shared space and unstable evolutionary strategies

This post probably doesn’t quite work, but at At War With The Motorist I continue the thread on shared space by considering the mechanism by which it works: risk compensation — the idea that when traffic management is ripped out, road users will perceive the road to be more risky […]


Lay Science: The Selfish Genius

This was originally written a year ago on a now disused blog. I’m reposting it here because I enjoyed writing it so much that I wouldn’t want it to disappear. People love a good argument with Richard Dawkins. So many people are so desperately seeking reassurance that he is wrong, […]


Evelyn Fox Keller on genes, evolution, and epigenetics

This is another archival repost from the old blog, first published way back in March 2008. I’ve been following CBC’s How To Think About Science series, and caught the Evelyn Fox Keller episode the other day. It was interesting, but there were a couple of issues that I just can’t […]


Origin Ch.13: Darwin the experimentalist

This post is part of a series on The Origin Of Species.  It was originally posted on the old blog in feb 2009, during the Darwin 200 celebrations. Two pages into chapter thirteen we get a fantastic image of Darwin pottering in his conservatory, dipping his duck in various fish […]


Origin Ch.12: Noah’s Ark

This post is part of a series on The Origin Of Species.  It was originally posted on the old blog in feb 2009, during the Darwin 200 celebrations. Oh dear, the topic seems to have taken a distinct veer into creationism, around here, and I fear that will not change […]


Origin Ch.11: Where the fossil record went right

This post is part of a series on The Origin Of Species.  It was originally posted on the old blog in feb 2009, during the Darwin 200 celebrations. The creationist site that I briefly reviewed yesterday repeated the claim that the fossil record does not support descent with modification, and […]


Having a BLAST with Darwin

-or- “(One of many reasons) Why genomics matters” This is an archival repost which was originally posted on the old blog in feb 2009, during the Darwin 200 celebrations. In chapter 14 of The Origin Darwin discussed embryological stages and their utility in classification. This utility derives from the fact […]


Origin Ch.9: Recombination

This post is part of a series on The Origin Of Species.  It was originally posted on the old blog in feb 2009, during the Darwin 200 celebrations. In chapter nine, Darwin takes a long look at hybrids. And I mean a long look: he can really go off on […]


Origin Ch.7: Adaptation

This post is part of a series on The Origin Of Species.  It was originally posted on the old blog in feb 2009, during the Darwin 200 celebrations. In chapter seven, Darwin responds to some more objections to his theory of natural selection. One such objection is that “many characters […]
