Question

Throw some light to the early stages of human beings?

Answer 1

Early Stages of Human beings

Explanation:

• Human evolution initiated with primates. Primates developed from other mammals from about 85 million years ago.
• Various divergences among apes, gibbons, orangutans occurred during this era, with Homini (including early humans and chimpanzees) separating from Gorillini (gorillas) about 8 millions years ago.
• Humans and chimps separated in evolution of about 7.5 million years ago.  

• Generally, it's believed that hominids first evolved in Africa then migrated to other areas. there have been four main stages of human evolution.
• The first, between four and 7 million years ago, consisted of the proto hominins Sahelanthropus, Orrorin and Ardipithecus.
• These humans may are bipedal, meaning they walked upright on two legs. The second stage, around four million years ago, was marked by the looks of Australopithecus, and therefore the third, around 2.7 million years ago, featured Paranthropus.

• The fourth stage features the mammal genus, which existed between 1.8 and 2.5 million years ago. human, which used stone tools and had a brain about the scale of a chimpanzee, was an early hominin during this period. The brain capacity would have increased due to handling of tools.
• This was followed by Homo erectus and Homo ergaster, who had double the brain size and will are the primary to regulate fire and use more complex tools. Human culture began 50000 years ago.

These are the early stages of human beings
