The evolution of human beings on Earth was a complicated process

The evolution of human beings on Earth was a complicated process related to animal extinctions. Some scholars connect the latter to human activities, while others explain everything by natural conditions’ changes. The recent scholarly findings prove that invasions of Homo sapiens to the Austronesian and American continents were the major factors that conditioned the extinction of numerous animal species (Carroll, 2001, pp. 81 – 82). These data allow at least hypothesizing that the recent scholarly findings bring the science closer to defining actual causes of animal species extinction, unknown to the prior scholars.
