Population replacements and founder effects in humans
TREE has an article in press looking at the impact of founder events on subsequent patterns of genetic diversity. The main argument of the paper, co-authored by Waters, Fraser & Hewitt (Founder takes all: density-dependent processes structure biodiversity), is that … Continue reading

More problems with the paleodiet
In my Anthropology of Food class we have spent the past two weeks talking about the technological, dietary, cultural and population health transitions from the late Paleolithic, through the origin of agriculture, to present-day industrial-scale food production, with much of … Continue reading
The Dmanisi mandibles
My latest paper examining metric variation in the Lower Paleolithic Dmanisi mandibular sample, co-authored with David Lordkipanidze, is available today via Paleoanthropology’s website (open access). Synopsis: The Dmanisi mandibular sample is a well-preserved, age-stratified set of remains, that poses interesting … Continue reading

Population level extinction in human prehistory readings, part 1
One of my current research projects is investigating the potential impact of population level extinction in human evolutionary history. I am focusing my efforts on Late Pleistocene Europe because it is a time and a place that we have a … Continue reading

In defense of equations
PNAS has a series of brief comments on the role that equations–and more broadly, math-heavy papers–play in the citation frequency of biology articles (see here, here, here, here and here). It appears to be the case that in at least … Continue reading
A blog (and model) to follow
If you have not already seen it, you should check out (bookmark, subscribe to the RSS) Haldane’s Sieve. Not only does it have a great title, but it is an amazing resource for discussions of contemporary evolutionary and population genetics … Continue reading

Opening the genome for understanding, not simply exploration
I regularly make the distinction between information and knowledge generated from genomic studies. Information is just that, the explorative identification of genetic diversity. What nucleotide base or allelic variant is where on what chromosome in the genome? The Human Genome … Continue reading
Neandertal-human admixture and early Homo
Last week’s pre-publication of a paper addressing the alternative hypotheses of Neandertal-human admixture vs. ancient African population structure, with respect explaining the signal of Neandertal DNA in living humans, has generated a lot of great posts. First, John Hawks has … Continue reading
