GEOLOGY

Detailed explanation-1: -The Holocene Epoch began about 12 thousand years ago and continues to the present. This is the epoch during which human beings became ascendant and within which all of recorded human history occurred.

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: -The Cenozoic is also known as the Age of Mammals because the terrestrial animals that dominated both hemispheres were mammals – the eutherians (placentals) in the northern hemisphere and the metatherians (marsupials, now mainly restricted to Australia and to some extent South America) in the southern hemisphere.

Detailed explanation-4: -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-5: -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.
