Last week, on his very popular blog, WhyEvolutionIsTrue.wordpress.com, Jerry Coyne ridiculed Nicholas Wade's NYT article discussing the negative consequences resulting from the anti-religious tone of most orthodox defenses of evolution.

Earlier blogs have covered horizontal DNA transfer between bacteria and from bacteria and fungi to animals. This blog will present some of the evidence for horizontal transfer in the reverse direction: DNA acquisition by infectious bacteria from eukaryotic hosts.

Symbiogenetic events included the origin of the eukaryotic cell. This major step enabled all the following evolution leading up to multicellular organisms, including us.

Was Darwin simply mistaken about the gradual nature of hereditary variation? Such ignorance would be unavoidable before we knew about Mendelian genetics and DNA. Or was there a deeper flaw in the theory that he (and Alfred Russell Wallace) propounded?

The genetics and genomics of bacterial antibiotic resistance and virulence teach us some fundamentally important lessons about evolution. They also pose some significant challenges to scientific explanation.
