Anthropogenesis is characterized by such a phenomenon, unique to wildlife, as a growing strengthening of the influence on the evolution of social factors – labor activity, social lifestyle, speech and thinking.
Group cooperation provided greater safety to human ancestors in open landscapes, the possibility of hunting large animals, freeing up time for the manufacture of more advanced tools, raising children, caring for the elderly, etc.
The improvement of tools was possible only on the condition of the transfer of techniques for their manufacture to a new generation. This helped to increase the role of people of the older generation who had experience in hunting, making tools, who knew edible and medicinal plants, who knew how to navigate the terrain, etc. Those groups of ancient people who used to pass on their experience to the young won the struggle for existence. The populations of people who made and used tools better displaced the lagging populations into areas less favorable for life, which led to their disappearance.
Collective hunting, work, the need to transmit information to their fellow tribesmen required the use of a complex system of mutual signaling, which contributed to the development of speech.
Complicated tools and labor processes, the use of fire, the appearance of articulate speech contributed to the further development of the cerebral cortex and thinking.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
