A genetic atlas of human history

Two papers caught my eye recently that have taken advantage of the proliferation of whole genome sequencing techniques in recent years. With prices of sequencing whole genomes coming down and down, biologists are having access to vast amounts of data. The 1000 Genomes Project was one of the first to collect the vast amounts of human genome data into a story that told of human population origins. The two papers that I saw recently extend this story. One provides data from nearly 1500 people throughout the entire world to trace the genetic legacies of Ghengis Khan and Alexander the Great. The other delves deeper into the dawn of homo sapiens in Africa, over 300 whole genomes and nearly 1500 genotypes – the African Genome Project.
