Ancient Human Migrations

Scientific understanding of the human journey out of Africa is always changing. In the past, scientists explored this story through the paleontological record of skeletons and human artifacts. Recently genetics has offered new insights into the story of human migration. Breakthroughs in technology allow for further understanding, but at the same time there are those that warn us to be careful in how we interpret what we find. Some people point to the history of Eugenics, as a warning about the way that human biases, including deep racism, shaped scientific findings and public understanding.  There are others, who argue that these new insights into the story of human migration provide further evidence that dividing human beings into racial groups is not a productive way to understand the differences between us since they uncover many similarities between many people across racial groups. Indeed, we all share both genetics and a long history of migration.
