I try to be careful when using the term "ignorant." The dictionary definition could apply to anyone who is "unlearned" or "uneducated" in a particular area, i.e. I am nearly completely ignorant when it comes to quantum physics.
I have several episodes of "Paleo World" on video tape, but not this particular one. In addition to peddling outdated ideas like bipedalism in hominids being related to climate change, have you noticed how cheesy the costumes are on these shows? The australopithecines look like rejects from "Planet Of The Apes"! They'd do better using Gurche's or Matterne's art to illustrate human evolution, so people could follow the story, not be distracted by the shitty "ape" suits.
