100 amazing and interesting facts about a human being

The human is a social being, possessing intelligence and consciousness, as well as a subject of socio-historical activity and culture. Originated on Earth because of the evolutionary process – anthropogenesis. Specific features of humans, distinguishing them from other animals, are uprightness, highly developed brain, intellection and articulated speech.

Humans study and change themselves and the surrounding world, create a culture and own history. The essence, origin, purpose and the place in the world of a human being have remained the main questions of philosophy, religion, science and art.

Distinctive features of humans: the ability to think and to make a free choice, take responsibility for actions, the existence of moral judgments. Describing people, scientists register their biological inappropriateness, the lack of specialization of the organs for any particular simple animal creature, the ability to produce tools, fire, and use them, the gift of speech, and the plasticity of behavior. People are the ones to have higher emotions, traditions, and the ability to think, assert, deny, count, read, plan, know about their mortality, and love in the true sense of this word. We also have a sense of humor, carry out our intentions, invent and create something new.
