6 thoughts on “The Megafauna Massacre: Humans responsible for the extinction of ancient species

  1. This was the actual Sixth Mass Extinction, the first anthropogenic extinction. The current extinction crisis should be called the Seventh Mass Extinction, the second anthropogenic extinction. The current situation has the potential to return the biosphere to the Zeroth Mass Extinction, before aerobic life replaced the original anaerobic microbes.

  2. Yes, you can always tell where Homo sapiens has been. Just follow us over the Bering Strait into what we turned into a megafauna graveyard. Then, of course, in the 19th century we wiped out bison by the millions, along with wolves, cougars, and bears by the thousands who were–imagine this!–competing with cattlemen for the land.
