The Noun Interpretation of "Man"
The emergence and development of human beings can be divided into several stages: in the first stage, Australopithecus Australopithecus (the latest ancestor of human beings who lived more than 5 million years ago) turned to live in groups on land, omnivore and use natural objects as tools (for hunting and using prey), and then began to process tools and occasionally make tools. This has made comprehensive preparations for the second stage. The second stage is marked by the appearance of primitive groups in the early stage of human origin (Homo erectus and Homo erectus are the oldest peoples). These primitive people made rough tools with stones, bones and wood, hunted animals and learned to use fire. Their descendants, that is, the ancients or Neanderthals, have been able to make tools with more complex shapes and uses, build primitive hand-built houses, and learn to make fires. The emergence of socialized mass production has caused the emergence of consciousness and language, making people body form. The formation of mankind has gone through hundreds of thousands of years (Southeast Asia, South Asia, pre-Asia, Africa). In the third stage, the primitive group became primitive society, and Neanderthals became modern people, which happened 35,000 to 40,000 years ago.
The characteristics of human beings are: completely upright posture, dexterous hands, complex and syllabic language and thinking brain; And has the ability to create tools and actively transform nature.
