Ancient people were more vegetated than modern people. They had long hair, tied up in tangles, because there were no combs. They were dirty and dressed in the skins of killed animals. The skull of ancient people was also different from modern ones. They had a pronounced large jaw and protruding brow bones. They differed from animals primarily in that they did not walk on all fours, but most importantly, they had fingers. No animal in the world has a thumb. This is a sign of human evolution.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
