Lab-meeting about high-altitude adaptation in humans

It is time for a new lab-meeting on Wednesday (September 1), and this time I was thinking that we should discuss a recent Science-paper where the auhtors present evidence for genetic adaptations to high-altitude living in Tibet. The paper can be downloaded here. Interestingly, there is also another recent study on the same topic in PNAS, which can be downloaded here. I suggest we read both of them in preparation for the lab-meeting on Wednesday.

These papers has received quite a lot of attention both in media and in the bloggosphere. I can recommend population geneticist Jerry Coynes blogpost about one of these papers on his excellent blog "Why Evolution is true". Coyne has also a more critical blogpost where he cautions against solely relying on statistical approaches on gene frequency changes to infer selection. Being an experimental evolutionary biologist and ecologist by heart, I could of course not agree more with Coyne.

Time of lab-meeting as usual: 10.15 in "Darwin", Wednesday September 1, 2010. Any fika-volunteer?

Also, do not forget that CAnMove organises a barbecue on the same day in the afternoon at 17.00 at the Biology Department. Contact Sophia Engel for more info.
