Thatoneguy said;This is probably accurate, but nothing to brag about. Other animals can also build simple tools. However only light skinned humans have ever built complex tools and built complex things with those tools.Yes, because they needed to. Light skinned humans emerged along with migration into colder climates and the need to invent new survival techniques in new ecological systems. One example of dark skinned people developing sophisticated tools is at the soutern tip of Africa, where very ancient peoples settled along the coast and invented specialized tools for fishing and prying open shellfish. They became fishermen instead of forest dwellers who enjoyed an abundance of fruits, roots, nuts, just for the picking, and no need for sophisticated tools.
Primitive humans who inhabited the coast of South Africa 165,000 years ago and lived on a diet rich in shellfish could be the original ancestors of everyone alive today, a study suggests.The people who lived in high caves at Pinnacle Point, overlooking the Indian Ocean near Mossel Bay, harvested and cooked mussels, used red pigment from ground rocks as a form of make-up and made tiny, bladed tools. Experts say they are very likely to be the ancestors of Homo sapiens, the anatomically modern human species which migrated across the world.
Coastal migration sounds very possible to me. Abundant sea food all along coasts fron south to north.
Pinnacle point
It is known that Homo sapiens evolved in Africa between 200,000 and 150,000 years ago but scientists are not sure where on the continent they first arose as a distinct species. The latest evidence points to the southern tip of Africa. Archaeologists working at Pinnacle Point identified stone tools and a red pigment used in ritualistic ceremonies which they believe could only have been used by humans showing "modern behaviour".https://www.independent.co.uk/news/science/first-humans-lived-at-southern-tip-of-africa-5328709.html
We know skin color itself has no effect on intelligence or creativity, it’s just that peoples who evolved in the temperate part of the world developed those skills after they developed lighter skin.People did not need dark pigment for protection of the sun in temperate parts of the world, what they did need is weapons to deal with new species of prey and predators. Light skin has nothing to do with intelligence. It is a result of adaption to temperate and colder climates. People do not think with their skin and only develop tools as needed for survival in specific ecosystems.
