<u>Question # 2</u>
The Paleolithic is a stage of the Stone Age in which people did not work pottery. The paleolithic coincides with the appearance of the first human beings and ends 8000 years before the birth of Christ. During the Palolithic, the human communities that inhabited the earth were nomadic groups, that is, they did not live in the same place but traveled following the animals they hunted (different types of megafauna such as mammoths and mastodon). As they were hunters and gatherers they followed the animals to capture them and took advantage of the routes they made to pick up the wild fruits. It is said that they lived in small family groups. Research shows that they lived mainly in caverns where they made paintings with natural ingredients. They dressed with the skins of the animals they hunted and used tools made of stone, wood and bone that they themselves carved.
