The journey of the modern mankind had been started 70.000 years ago from East Africa. They had travelled to all around the World, they had met with different kinds of animals, plants, geo and climates. Thanks to their great adaptation ability, they had succeeded to survive however lots of species who had met with them could not make it even some of them were cousins of Sapiens.
Trace of early immigrations shows that Sapiens first passed to Middle East approximately at 100.000 years ago, however first groups of sapiens were not successful and they extinct. 70.000 years ago the next sapiens waves hit to the middle east, this time they were more intelligent. They crossed to the Europe 40.000 years ago, to the Australia 45.000 years ago and to the North America 16.000 years ago. At the time, sea levels were low enough that a land bridge connected north-eastern Siberia with north-western Alaska. It was cold and not suitable for ordinary ape, however intelligent sapiens learnt to cover and heat their body, to build shelters, to hunt at that climate. Why did they chose to immigrate to Arctic land is still controversial question. One of the reasons of this choice could be probably wars among different tribes whereas the other reason could be better protein opportunities.
As 30.000 years ago, this immigration was another holy journey of mankind, on the other hand the great devastation for many species that had been living in America for billions of years. Sapiens moved to South step by step by the help of global warming around 12.000 years ago. Despite climate change, their great adaptation ability assisted them in ruling the nature and world. Every places where Sapiens had stepped into, had been sharply effected.
Within 2,000 years of the Sapiens arrival, most of these unique species were gone. According to current estimates, within that short interval, North America lost thirty-four out of its forty-seven genera of large mammals. South America lost fifty out of sixty. The sabre-tooth cats, after flourishing for more than 30 million years, disappeared, and so did the giant ground sloths, the oversized lions, native American horses, native American camels, the giant rodents and the mammoths. Thousands of species of smaller mammals, reptiles, birds, and even insects and parasites also became extinct
