Population Differences in Androgens Fail to Support Differential-K Theory

by Scott McGreal in Eye on Psych

A recent paper attempts to test predictions of Differential-K Theory about race differences using data on population differences in androgens.Close examination of this data shows that the predictions fail.... Read more »

Surfing the wave of genetics: the man who invented genetic landscapes

by EE Giorgi in CHIMERAS

  Today is the 90th birthday of the one and only Luigi Luca Cavalli-Sforza, professor emeritus at Stanford University and a pillar of population genetics. Oh, and in case you couldn't tell by the name, he's Italian, too. Not that I'm biased, mind you.Cavalli-Sforza is best known for his book The History and Geography of Human Genes, in which he reconstructs the history of human migrations by mapping the distribution of gene alleles and correlating gene frequencies in populations with the ge........

An addendum on Haldane's dilemma and the use of mathematical models

by EE Giorgi in CHIMERAS

Last week, my post on Haldane's dilemma garnered many views. I'm glad people are reading it and I hope they find it useful in clarifying the great impact of Haldane's 1957 paper. For those of you interested in digging deeper into the topic, the Panda's Thumb discusses the matter in a 2007 post, and Gene Expression covers it here. I just have an additional note, which is a bit of a pet peeve of mine, but as I read about the reactions to Haldane's paper scattered all over the Internet, I realized........ Read more »

Haldane's dilemma

by EE Giorgi in CHIMERAS

  Today is JBS Haldane's 119th birthday. Together with Fisher and Wright, Haldane is considered the founder of the mathematical theory of population genetics. Population genetics studies how allele frequencies (the prevalence of different copies of genes) change in populations due to processes like natural selection and genetic drift. In other words, how mutations arise and how they undergo a turnover in the population. To celebrate Haldane's birthday, I thought I'd discuss his 1957 paper, ........ Read more »

The Latest On: When Five Hundred Tigers Are Not Enough

by Kelly Grooms in Promega Connections

It is sad but true that the latest news has not been promising for wild tiger populations. In September, an article published in PLoS Biology (1) estimated that the best hope of saving the wild tiger population would be to shift focus to source sites, which¬†are “…at spatially well-defined priority sites, supported by proven best [...]...

Ghosts in the Molecular Machine

by Southern Fried Scientist in Southern Fried Science



The extent of migration among populations drives population structure. With enough migration, populations become homogeneous and behave as a single larger population. As migration rates decrease, populations drift apart and become differentiated. By measuring the amount of differentiation, we can determine the extent of migration between them. But what happens when there are unsampled [...]... Read more »
