Nautilus is running a nice interview with Lee Berger about Homo naledi and other things: “The Man Who Used Facebook to Find an Extinct Human Species”.
From the interview:
We had senior anthropologists saying there was nothing left to find, we should stop teaching graduate students, you’re not going to find fossils in the soil anymore, they’re a declining resource. The richest fossil hominin site on the continent of Africa was less than a mile from the most explored locality on the continent. What does that tell you? That there must be extraordinary findings still.
Many interesting points in the interview about how paleoanthropology has been changing into a team-oriented science.
