Hank tells us about new and confusing discoveries in the field of Human Evolution.

One new fossil discovery helps shed some light on early titanosaur evolution, while another leads to some controversial claims about dicraeosaurs.

Take a close look at some of the strangest-looking animals evolution has created.
