Human Microevolution and the Atlantic Slave Trade.

The article presents a study which analyzes the genetic structure of São Tomé, the major island of the São Tomé e Príncipe archipelago located in the Gulf of Guinea. The researchers used a comprehensive sampling strategy with a two-tiered approach based on the sorting of sampled individuals into genetic clusters using multilocus microsatellite genotypes. The results show that clusters and clines are not necessarily mutually exclusive representations of human genetic patterning.
