Open Thread, 8/30/2015

A week ago a friend was asking about my opinion on a long article that was shared on Facebook about ISIS and the nature of Islam. It came up that I don’t talk about religion too much on this blog in the same way I did before 2010 or so. The primary reason is that […] Continue reading

Admixture beyond the single pulse

Graham Coop’s group has been exploring the implications of more complex models of spatial structured genetic variation and admixture for the last few years. I’ve already pointed Gideon Bradburd’s SpaceMix preprint, which attempts to differentiate genetic relatedness due to geographic proximity and therefore continuous gene flow, as opposed to an admixture event which is not […] Continue reading

As man is, the dog shall be

When is a jackal a wolf? All the time apparently. At least according to a persuasive new paper, Genome-wide Evidence Reveals that African and Eurasian Golden Jackals Are Distinct Species. First, let’s put this in context. Canids area big deal. They’re big social mammals whose distribution and speciose character have undergone big changes across the Pleistocene. […] Continue reading

I get notifications for a lot of different things. Some of them are way off base (e.g., I think at some point a publicist sent me the contact information of a client who had written a book on homoepathy?). But some of them are spot on. I drink a lot of coffee. On the order […] Continue reading

A Note on Uralic (& Finnish) genomics

I was playing around with some data, and I saw a strange migration from Amerindians to Finns in one run. I looked through replicate runs the same pattern reoccurred. The weird thing is that I had a Siberian data set in there (Ngannassan, Koryak, and Chukchi). The Amerindians were a mix of Pima, Maya, and […] Continue reading

Selective sweeps on the X chromosome of homonoids

About ten years ago David Reich and Nick Patterson were involved in a paper which posited “complex speciation” in the lineage that led to humans and chimpanzees. What that means is that there was some hybridization between the proto-chimp/bonobo lineage, and that leading to hominins. As the authors state: “These unexpected features [of the genome] […] Continue reading

Old Europeans were old school thugs

14 – And Moses was wroth with the officers of the host, with the captains over thousands, and captains over hundreds, which came from the battle. 15 – And Moses said unto them, Have ye saved all the women alive? 16 – Behold, these caused the children of Israel, through the counsel of Balaam, to […] Continue reading

Selection is often a mystery

If population genetics is “study of the distributions and changes of allele frequency in a population,” then the understanding of the maintenance of variation (or lack thereof) is one of the major topics of focus. In the first half of the 20th century when there was a lot more theory than data there were arguments […] Continue reading

Tamil Brahmins are alien & native to South India

Whenever I post about Indian genetics there are really weird comments that pop up which go like this: “this guy doesn’t know anything about genetics, he totally ignores the research [usually published in the late 2000s and utilizing mtDNA haplgroups] of [Indian researcher that I don’t really know] which has proven [something which has been […] Continue reading

Multi-level selection, red in tooth & deme

People routinely mistake the action of adaptive evolutionary process as occurring on the level of the species. Not only is this a misunderstanding that crops up in the general public, but I’ve talked to biologists who make the same mistake. The reality is that the mainstream tradition in modern evolutionary biology is very skeptical of […] Continue reading

About a year ago I heard a pop song on my Pandora that was a little less annoying than Ke$sha, and I looked up the singer up. Her real name was Jessica Malakouti. My immediate though was “that last name sounds Iranian.” Then I watch the video above, and my revised thought with the new […] Continue reading
