Over the past half decade, ancient DNA research has revealed some surprising aspects to our evolutionary history during the past 50,000 years. Perhaps the most startling of these has been the extent to which the ancestors of living people across the planet interbred with other closely related species of human. But where in the world did these cross-species matings occur? Which archaic species were involved?

Historians have deduced that the impetus behind all mining activities was a need for ochre pigments. Cave dwellers might have traveled as far as 25 miles to obtain iron earth pigments for their paint in the Lascaux area.
