Just a quick round-up of some links. On the same day I wrote about Gerobatrachus hottoni PZ Myers at Pharyngula also posted regarding the transitional amphibian, including a beautiful photograph of the fossil. I also logged in a few days ago to find to my surprise that my recent post on the non-necessity for mice of some genes that are required in humans was included in the Gene Genie blog carnival. This blog carnival covers human genetics, usually focusing on the field of medicine. Medicine is another interest of mine (I skim New England Journal of Medicine and The Lancet weekly), but since this blog is focusing on evolutionary biology I haven’t covered medicine much here, and it hadn’t occurred to me that post would meet inclusion in Gene Genie! You can read the current Gene Genie at Highlight Health. I also read the medicine-themed blogs Denialism and Respectful Insolence, so check those out if medicine interests you.
I checked in on Nature earlier, since a new issue comes out tomorrow, and find that there’s an article combining two favorite topics of mine—malaria and sex ratios. I can only read the abstract from home, so I hope the suspense doesn’t keep me up too late. I anticipate that paper will show up on my blog shortly.
ANIMAL MODELS are widely used in medical research, sometimes in testing new drugs for safety before human trials, other times as model systems for human diseases. Like all mammals, humans and mice share most of their genes, and maintain high sequence similarity. These factors suggest that many of these genes should share the same role. A new study in Proceedings of that National Academy of Sciences examines this hypothesis.
