Gene Expression

Archives for October, 2006

I noticed today that I was receiving a lot of search engine queries for black and white twins. Well, I have posted on it several times, but I thought it was a bit much, so I checked the news, and lo & behold, another case just popped up. Like the Australian twins the mother here…

Genetics of hair color

A reader emailed me asking about the genetics of hair color. Since I’ve discussed the topic before I simply pointed them to the query of the topic on my other blog. But, I thought it might be good to directly answer two specific questions: Why do many people have much lighter hair during childhood? The…

Religion, good and bad and all that

John Wilkins has a good post on religion, I tend to agree with its general thrust though I might quibble with details. Not being gifted with much marginal time right now, a few quick thoughts: 1) I believe that institutional organized religion, e.g., Christianity, Islam, etc., can increase the magnitude of a social vector, but…

Ruchira Paul brought this article to my attention: Before you request a paternity test, spend a few minutes looking at your…

Brains are expensive

One of the many hypotheses in palaeoanthropology is homonids shifted to meat eating because it was metabolically rich and allowed the increase in our brain sizes. Well, there might now be some support from primate analogs finally, Study suggests evolutionary link between diet, brain size in orangutans: In a study of orangutans living on the…

“Black” & white twins again

Hsien-Hsien Lei points me to another story about black and white twins. First, the “black” twin is clearly mixed race, her skin color is between the modal complexion of Europeans and sub-Saharan Africans on the von Luschan scale. The “white” twin on the other hand does seem to exhibit the color of someone of European…
