The human species of the Homo genus (Homo) has been extinct for a long time. Neanderthal Man (Neanderthals), Homo habilis (Homo habilis), Homo erectus (Homo erectus) and our species Homo sapiens (Homo sapiens). Occurred about 300,000 years ago in Africa. It is said that the trait that determines the evolution of the Homo genus is the tendency to increase body and brain size. Compared toHomo Habitat Majlis and our species with a body weight of more than 50% of the brain is larger than 3 times, but what is driving change is still much debate
recently, a research team led by University of Cambridge. in england and the University of Tubingen in Germany have compiled body and brain measurements offossilsmore than 300 Homofound around the world. By combining that information with the reconstruction of the global climate of the last million years. which identifies the climate they experienced as human beings. The findings indicate thatweather, especially temperature, has been the main driver of body size change over the past million years. It was found that larger bodies developed in cooler regions. The larger size is believed to act as a shield against colder temperatures.
Researchers revealed that It can be seen from the people who live today. Those who live in warm climates tend to have smaller body sizes. Those who live in cooler climates tend to be larger. The brain size of the Homo genus tends to be larger when they live in less vegetative areas, such as open grasslands. These people tend to hunt large animals for food. which is a complicated task This could therefore be the driving force behind the evolution of the larger brain.
