The Cenozoic Era was the first era that saw humans evolve. Much of what the common population thinks of as evolution all happened in the Cenozoic Era. The first period of the Cenozoic Era is called the Tertiary Period.Recently, the Tertiary Period has been broken down into the Paleogene Period and Neogene Period.he modern human evolved and became the dominant species on Earth. Other mammals on Earth continued to diversify and branch off into various species. The same happened with marine species. There were a few extinctions over this time period as well, due to the changing climate.
Itâs one of my favorite stories in the history of paleoanthropologyâone that involves an anatomist youâve probably never heard of and an infant who was attacked by an eagle and dropped into a hole almost three million years ago. The idea that humans evolved in Africa can be traced to Charles Darwin. In his 1871 book The Descent of Man, Darwin speculated that it was âprobableâ that Africa was the cradle of humans because our two closest living relativesâchimpanzees and gorillasâlive there.
