How did primitive man survive?

Primitive man, in conditions of real danger around him, led a predominantly hunting lifestyle – he extracted meat, fruits of plants, made weapons from branches, stones, animal bones and other resources that were available. For lodging, either caves were used, or, later, primitive dwellings, also made of animal bones, or sticks and stones lying around. When a fire opened for a person, he was able to cook fried meat for himself and build more durable structures, through, for example, firing clay. The fire was also used to generate heat in cold seasons.
