Caucasian difference?

Very recent studies indicate the Caucasian race, which probably emigrated from central asia, may show some difference in some utilizations from most other races. In modern times, it is found that Caucasians have a tendency to build structures.

Collected information seems to indicate the Caucasians more readily resorted to building or developing shelters or living in caves and fires due to the cold climates thousands of years ago, in contrast with others that lived in temperate or warm tropical climates. 

They seemed to tame and husband some animals. There has been evidence that dog lived with man, at least in Europe, for longer than was thought. A finding has found a burial site of 14,200 years ago with a dog buried with the humans in Germany. Caucasians seem to be the most comfortable with dogs domesticated and as pets.

This may be found less so with African people and others. It may indicate that the Caucasians had come from a different direction than the generally assumed Africa source due to above noted observations of lifestyles. It is recently noted that early Caucasians patina was probably a little darker than today's white pigment. Taking shelter for long periods of time in caves, etc. may have dimmed the patina. It is also said the blue eyes, according to genome studies, came to fore about 60,000 years ago.

A very recent discovery, released in 2018, around the state of Israel indicates an old settlement by people who do not appear to have been from the African migrations. There may be phenotype differentiations. If this holds, it may point to a branch that arose from a different location. Possibly central Asian steppes.

A few suggested that coarser traits in a more temperate environment might be shed  over the years, it would be a decreased gene which would eventually become recessive and no longer recur in the genome.

On a bigger picture, it is held that Homo Erectus left Africa 1 million years ago, and Homo Sapiens left Africa 80,000 years ago. And did Neanderthal had a bigger cranium than Homo Sapiens?

Further findings of societies will bear out more evidence of past living in older societies.
