Early Hominids and The Pleistocene and Holocene Eras

Since the Pleistocene, the human society has rapidly expanded, developed its innovative ways to protect its territory and move it throughout the land. As the people living together gather, these societies become stronger and consume more meat (gigantic animals) over time. To support this development, the more humans eat more mammals, the more they absorb more protein. When humans consume a large amount of protein, they create stronger muscles that stimulate the brain's activity.

Human civilization began to think that our era - the Holocene - or the world of human being - is unique. But, in fact, we still belong technologically to Pleistocene. This is probably due to the placement of the continent and how it affects the flow of water in the ocean. That period began about two million years ago, with the swell of glaciers, humans disappeared gradually in various forms. Because there is evidence that Sapiens is the warmest species in the species, ice spreads and eucalyptus habitat with a rich ecosystem is the habitat for eucalyptus poor tundra, Neanderthals, Denisovan and others I will adapt to these northern people. When the food runs out, the climate is finally on the verge of extinction

In late Pleistocene and early Holocene, most mammoth populations disappeared with most Pleistocene giant animals including Colombian mammoths. This extinction is part of Quaternary extinction, which began 40,000 years ago and reached its peak from 10,000 to 10, 500 years ago. The main factors that scientists have about hunting and climate change (the cause of shrinking habitat) are whether they can be divided by the main factor that will destroy mammoth, or a combination of both. Regardless of cause, large mammals are less vulnerable to small mammals because of their low population and low reproductive rate. Different mammoth groups did not disappear at the same time within those ranges but gradually disappeared over time. The majority of the population disappeared from 14000 to 10 000 years. The last mainland population existed on the Kyttyk peninsula in Siberia 9, 650 years ago.

Although not as dramatic as the climate change that occurred during Pleistocene, a significant change in the global climate occurred during the global climate. At the beginning of the Holocene around 9, 000 years ago, the atmospheric circulation and precipitation patterns seemed to be very different from today's ones. For example, there is evidence that the current Sahara desert is relatively damp. Changes from one climate to the other are due to the gradual change of the sunshine pattern during the Holocene and the interaction of these models with large scale climate phenomena such as monsoon and El Nino / Southern Oscillation (ENSO) It is caused by.
