GENERAL GEOLOGY

Detailed explanation-1: -The Cenozoic cooling trend culminated in an ice age during the Pleistocene Epoch, which is also the epoch during which the human genus (Homo) and human species (Homo sapiens) evolved. Human beings became ascendant, and all of recorded human history occurred during the Holocene Epoch.

Detailed explanation-2: -From the extinction of the dinosaurs until today, the Cenozoic Era is the age of mammals. Mass extinctions create opportunities for new life to thrive, and mammals filled the gap that dinosaurs left behind. They evolved into many species you would recognize today-including humans!

Detailed explanation-3: -Life during the Cenozoic Era Later in this period, rodents and small horses, such as Hyracotherium, are common and rhinoceroses and elephants appear. As the period ends, dogs, cats and pigs become commonplace. Other than a few birds that were classified as dinosaurs, most notable the Titanis, the dinosaurs were gone.

Detailed explanation-4: -The era that Homo sapiens first appeared was during the Cenozoic era, Quaternary period, near the end of the Pleistocene epoch of the present age or between 300, 000 and 200, 000 years ago. Homo sapiens are a very recently evolved species compared to the other inhabitants of this planet.
