population dynamics
Interaction and mixture: big picture and small
From the level of function of a single gene up to the movements of entire populations, our evolution was built from mixture.

Growing genetic data suggest a two-phase model for prehistoric population expansions in Africa
I describe results from two papers of African genetic variation, which show that the population growth from agriculture followed an earlier demographic expansion.
Modern human origins was more interesting than a single point of dispersal
A study of SNP variation across Africa enables us to look at a structured ancestral population long before 100,000 years ago.
Why do some invasive species start to succeed only after a delay?
Reviewing a body of evolutionary theory that tries to understand the ultimate success of some invasions after a lag.
