Question

Quizplus · Accepted Answer

Cavalli-Sforza's phylogenetic tree of the world's populations shows that the genetic distance between African populations and all other populations is the greatest, indicating that the earliest genetic event was the separation of African populations from all others. This is supported by other genetic studies that suggest modern humans originated in Africa and then migrated to other parts of the world. The peopling of the Americas and the arrival of humans in Australia occurred much later in human history.
