Out of Africa model most likely

Statistical evaluation of alternative models of human evolution: An appropriate model of recent human evolution is not only important to understand our own history, but it is necessary to disentangle the effects of demography and selection on genome diversity. Although most genetic data support the view that our species originated recently in Africa, it is…

Donors Choose update

OK, last update on this obviously because it is the last day of the month. A few readers really went wild in the last few days (in a good way) and from only 5 donors 508 students were impacted! (check the Leaderboard for the breakdown) Thank you very much! So if you have any spare…

How were the Americas peopled?

Until recently archeologists held to a model called Clovis First which posited that the Amerindians were descended from Siberian hunters who swept down from Beringia 13,000 years ago and spread rapidly north to south. Findings such as Monte Verde have thrown a cloud over the cleanliness of this hypothesis and there doesn’t seem to be…

Over at Ross Douthat’s blog, a giggle-inducing comment: It seems to me that Mormonism is indeed a lot more illogical than mainstream Christianity. It suffers from logical contradictions that Christianity does not- for example, how can someone be retroactively baptized? Why would God say that polygamy was OK for Brigham Young but then not OK…

Who’s afraid of nuclear power?

Just listened to an interview on NPR with the author of Power to Save the World: The Truth About Nuclear Energy. She mentions how she had a reflexive prejudice against nuclear energy and generally opposed its use because of her environmentalist impulses. That’s not surprising of course, people are terrified of nuclear energy because of…

The end of capitalist porn?

Interesting piece which chronicles the decline in the DVD driven profits of porn companies due to “user generated porn.” Porn is in some ways sui generis, so this is an interesting trend. Check out the traffic of YouPorn vs. Facebook.

Neandertals had red hair! (OK, some)

Sometimes science is just too cool! A Melanocortin 1 Receptor Allele Suggests Varying Pigmentation Among Neanderthals: The melanocortin 1 receptor (MC1R) regulates pigmentation in humans and other vertebrates. Variants of MC1R with reduced function are associated with pale skin color and red hair in humans primarily of European origin. We amplified and sequenced a fragment…

Contingency & evolution

If you like the science on this weblog, I highly recommend Laelaps, Brian Switek’s contribution to the ScienceBlogs network. Where I am more micro and anthro oriented he is more macro and spans the whole tree of life. I’m really glad he’s on ScienceBlogs; Laelaps adds to the diversity in an interesting way. In any…
