Hominid fossils discovered in Kenya
by Ana Maria Ciobanu


Two hominid fossils were discovered in Kenya. This discovery will bring light in many dark chapters of the human's evolution. Previously it was believed that the hominid Homo habilis had evolved into the more advanced Homo erectus which eventually evolves into us. The new fossils discovered show that Homo habilis and Homo erectus must have co-existed 500.000 years in the Turkana basin area, the region of East Africa where the fossils were unearthed. The broken upper jaw-bone found in Kenya was attributed to Homo habilis because of its distinctive primitive dental features and was dated to be about 1.44 million years old. The skull was assigned to the species Homo erectus and was dated to be approximately 1.55 million years old. These new dates can prove us the two species have lived together, side by side. Researchers say that the fact they coexisted for so long means they weren't in direct competition for resources and that they had their own distinct ecological niches. Both species could have been stone tool-makers, but it is possible that the more mobile Homo erectus could have been a skilled hunter. Year by year, what we know about evolution changes; light comes in chapters of our existence we didn't even know about. We're just starting to learn more about life, nature, ourselves and let's hope knowledge isn't limited...
