What is human evolution?(1)

Human evolution is the lengthy process through which modern humans (Homo sapiens) developed from earlier hominins, our ancient ancestors, over millions of years. This evolution involves both physical and behavioral changes that enabled humans to adapt to various environments and challenges.

Key Aspects of Human Evolution:

Origins of Humans:

Human evolution began with the divergence from a common ancestor shared with chimpanzees and other great apes around 6 to 7 million years ago. Over time, various species of hominins (early human relatives) emerged, such as Australopithecus, Homo habilis, Homo erectus, and finally Homo sapiens.

Bipedalism (Walking on Two Legs):

One of the first major changes in human evolution was the ability to walk upright on two legs (bipedalism), which is thought to have started around 4 million years ago. Bipedalism freed the hands for tool use, increased the ability to travel long distances, and provided advantages in different environments.

Brain Development:

Over millions of years, the human brain expanded significantly. Early hominins had smaller brains, but species like Homo habilis and Homo erectus showed gradual increases in brain size. Modern humans have relatively large brains, which allow for complex thought, language, and problem-solving.
