When jawbones and teeth were discovered in Ethiopia, it left people wondering if this could be a new species. "there are sufficient differences in the jaw architecture and size and shape of the teeth to mean that this is a new species, indicating that our ancestry is more complicated than previously thought", says a researcher working on the project. It shows that  that several hominin species coexisted during this period. The word "hominin" is used to refer to human species. This discovery has created a lot of discussion on the topic. I think this is dope!!!!!
