Sequences From First Settlers Reveal Rapid Evolution in Icelandic mtDNA Pool
A major task in human genetics is to understand the nature of the evolutionary processes that have shaped the gene pools of contemporary populations. Ancient DNA studies have great potential to shed light on the evolution of populations because they provide the opportunity to sample from the same po...
