Even with all our modern technology and advanced science, we still know relatively little about the origins of our fascinating species. We have an idea about the natural processes that have led to the emergence of Homo sapiens as we know ourselves today as well as the nature of some of our ancestors. We also possess insight into other archaic human species that we once shared this planet with. Even though we have these bits of information and a general picture of what happened, much about our origins and early history remains mysterious. ¿
