NEW YORK – A new collection of human genomes from across the world illustrates the genetic diversity of the global human population.
The ancestors of modern humans are thought to have diverged from the ancestors of Neanderthals and Denisovans between 500,000 and 700,000 years ago, with modern humans arising in Africa within the past few 100,000 years. About 50,000 to 70,000 years ago, some humans expanded out of Africa and mixed with more archaic groups in Europe and Asia.
