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.
Modern humans are theorized to have evolved from archaic humans, who in turn evolved from Homo erectus. Varieties of archaic humans are sometimes included under the binomial name Homo sapiens (Latin: wise man) because their brain size is very similar to that of modern humans. Archaic humans had a brain size averaging 1200 to 1400 cubic centimeters, which overlaps with the range of modern humans.
