Recently, a facelift was completed and the appearance of a creature known as Australopithecus anamensis was modeled. He is considered one of the oldest known human ancestors, and therefore scientists were eager to find out what he looked like. Moreover, until 2016, they had only scattered fragments of facial bones at their disposal, until a well-preserved skull was discovered in Ethiopia.
Due to the fact that scientists substituted human eyes with a conscious gaze in the model, Australopithecus anamensis seems smart and even cute. Which, of course, is far from the truth - 3, 8 million years ago, the hominid was much closer to the beast than to an intelligent creature. This is partly justified by the long-developed model of origin from the wild A. Anamensis of another species, A. Afarensis. This includes the famous Australopithecus Lucy, who already possessed the rudiments of reason.
Everything changed dramatically after building the model and comparing it with other hominid species. It suddenly became clear that the skull of A. Anamensis contains not only "wild features", but also many "advanced features" that are considered signs of evolutionary development. Moreover, some of these traits are even more developed than those of the same Lucy. So which of them is the ancestor of whom?
In the updated version of the human family tree, A. Afarensis was placed a little earlier than A. Anamensis, just some 100, 000 years. And this does not mean that they are descended from each other, the two species could well coexist for a long time, so that their union gave birth to a new, advanced hominid. Or, conversely, one of the species evolved and survived the second, as has often happened in the history of life on Earth. This means that scientists still have a lot of work to do.
