[The internet is down at the Kirksville Holiday Inn. The only other time this has happened to me was when I was in Russia. What this means is that posting may be light today. Fortunately Greg prepared a post on a recent talk he gave about evolution, which is below. JAC] by Greg Mayer Jerry […]

Preserved protein from an 80-million-year old dinosaur support the dinosaurian origin of birds

In this week’s Science we find a paper by Schweitzer et al. (total of 16 authors!) that has a quite remarkable result. (See the one page summary by Robert Service here.)  The upshot is that protein-sequence data from an 80-million-year old duckbilled dinosaur supports the dinosaurian origin of birds. This story has a bit of […]

What counts as evidence for evolution?

A couple of reviewers of WEIT (and some of my friends and colleagues) have pointed out the book’s dearth of molecular evidence for evolution.  For example, why didn’t I stress that organisms thought to be related based on morphological similarities also show similar relationships in their DNA sequences?  That is, DNA phylogenies generally match morphologically-based […]
