The Lost Tribes of Humanity

The Lost Tribes of Humanity: There have been several species of human ancestors that are now extinct, including Homo neanderthalensis (Neanderthals), Homo erectus (upright man), Homo habilis (handy man), and Homo naledi. These species were our closest relatives and shared a common ancestor with modern humans, but are now extinct and are known to us only through fossils and other physical evidence. Some of these species, like Neanderthals, were quite similar to modern humans in many ways, while others, like Homo erectus, were more primitive and had more ape-like characteristics. The exact causes of the extinction of these species are not well understood, but likely involved a combination of factors such as changing environmental conditions, competition with other species, and possibly even interbreeding with modern humans.
