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: -Derived from the Greek for recent life, it reflects the sequential development and diversification of life on Earth from the Paleozoic (ancient life) through the Mesozoic (middle life). Today, the Cenozoic is internationally accepted as the youngest of the three subdivisions of the fossiliferous part of Earth history.

Detailed explanation-3: -The Cenozoic Era is the “Age of Mammals.” North America’s characteristic landscapes began to develop during the Cenozoic. Birds and mammals rose in prominence after the extinction of giant reptiles. Common Cenozoic fossils include cat-like carnivores and early horses, as well as ice age woolly mammoths.

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.
