Tales of a Fossil Hunter

If looking for ancient bones to dig up sounds like hard work, that's because it is. According to anthropologist Donald Johanson, even modern tools such as GPS don't save scientists from having to "look and look and look and look" for fossils. Yet as the discoverer of the famous "Lucy" skeleton knows, one big find can be life-altering, world-shaking, and downright funas when he and his then-girlfriend named the skeleton after a Beatles song they were listening to at the time.

In his Big Think interview, Johanson discusses the scientific legacy of the "Lucy" find, as well as the "First Family" group of fossils thatwhile less of a media sensationmay actually have been his most important discovery. He also weighs in on the mystery of the Neanderthals' disappearance and illuminates the origins of human creativity, arguing that art did not begin in the Lascaux cave era but rather accompanied us out of Africa.


It's precisely the story of "the emergence of ourselves" on the African savannah that excites Johanson most about anthropology. He believes that as we learn more and more about the biology, behavior, and culture of early homo sapiens, we must increasingly confront the implications of the fact that, "regardless of what we look like on the outside, genetically, on the inside, everyone is an African."

Why a federal judge ordered White House to restore Jim Acosta's press badge

Strange Maps
  • America's two political tribes have consolidated into 'red' and 'blue' nations, with seemingly irreconcilable differences.
  • Perhaps the best way to stop the infighting is to go for a divorce and give the two nations a country each
  • Based on the UN's partition plan for Israel/Palestine, this proposal provides territorial contiguity and sea access to both 'red' and 'blue' America

Surprising Science
  • The new definition of a kilogram is based on a physical constant in quantum physics.
  • Unlike the current definition of a kilogram, this measurement will never change.
  • Scientists also voted to update the definitions of several other measurements in physics.
