Four-million-year-old remains in Ethiopia have provided the first hard proof of a link between two key stages of human evolution by bridging the gap between pre-human species, paleontologists said.
“For the first time, we found fossils that allow us to connect the first phase of human evolution and the second phase,” Dr Berhane Asfaw, anthropologist and co-research director of the project that found the remains, told a news conference Wednesday in Addis Ababa.
