The Slim Odds of Becoming a Fossil - Louise Leakey

The entirety of what we know about our pre-human past comes from fossils. However, National Geographic Emerging Explorer Louise Leakey explains that although she's been piecing together our human history using fossils, the odds of any single individual turning into a fossil and then working their way back to the surface are remarkably slim. Furthermore, thousands of years of wind blowing, water flowing and earth shifting can scatter remains, so that she never finds complete skeletons. Leakey's job is to then surmise the best she can about entire species based on the smallest hints from our ancestors millions of years ago.
