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.
the variety or species of humans that was intermediate between Homo erectus and modern people (Homo sapiens). The first archaic Homo sapiens may have evolved as early as 650,000 years ago, but most lived after 300,000 years ago.The last and most well known of them were the Neandertals, who survived until nearly 28,000 years ago. Archaic Homo sapiens have also been referred to as archaic humans and early Homo sapiens.. very early form of archaic Homo sapiens in Europe and North Africa that lived from about 800,000 to 200,000 years ago. In an alternate interpretation, some researchers consider Homo heidelbergensis to be a separate species. Homo heidelbergensis may have been the ancestor of the Neandertals.
