Prions wiped out most human life in existence at the time, at some point during the paleolithic. A global prion super-pandemic somehow happened, and our genomes still bear the scars to this day. This would have bottlenecked our species down to a population of thousands, from an initial pop of millions. All humans alive today are descended from the handful of survivors of that.
