The person holding the spear is from the Paleolithic Times because he has less advanced tools. The person on the left is from the Neolithic Times because he relies on raising crops and livestock unlike the Paleolithic person.
Before the Neolithic Times, The Paleolithic people. would hunt animals and gather plants, which is less efficient than raising animals because isn't enough food in one place.
What are you doing?
The Neolithic people lived in large groups so that they could share and divide work, similar to like the man in the back, picking oranges.
I'm hunting your cow for dinner
The paleolithic people had less jobs than the neolithic people. In paleolithic times they had few jobs like farmers, weavers, and toolmakers.
Why don't you just raise your own?
In neolithic times, they had more specialized jobs. One example of this are traders. They traveled far to get goods thy did not have yet.
Hey! That's a good idea!
Though both the Paleolithic people and the Neolithic people are somewhat similar, I think it the neolithic times was a better time to live in because they had a more efficient and advanced lifestyle than the Paleolithic people.
