The term primative brain.

I can't rationalize the term the primitive brain only in reference to the age or time. Like the cave man. I understand then how he perceived his world then. But in today's world it's somewhat different. I can see evolution in time. I would guess man changed from primate to civilized over time. It seems man has adapted to his environment? Paul

Life back then must have had a lot to do with plants. The cave drawings probably were ideas about new plants and how to make the plants thrive. Evolution of a person happens when the person lives in the future though. Better to live in the present and leave evolution to run it's course.
