>>>>>Consider the following scenario/explanation/theory: The group
commonly referred to as Asian was a primary human subtype.
Chimpanzee-like human ancestors developed into this type first. It is a
type adapted to forest-inhabitation: medium skin because of no
excessive exposure to sunlight. Straight hair, because of no excessive
exposure to heat. Curly hair allows evaporation of perspiration from
the head at increased rates for more efficient cooling. As the
rainforest becomes overpopulated with the Asian types, food must be
secured from outside the rain forest to support the growing population.
Warfare likely over resources. A sub-group of the Asian type is ejected
onto the harsh grassland, where they must survive heat, radiation, no
familiar food, quick-moving animal attacks, etc. They must chase and
capture faster animals for food or raid the rain forest. This is the
environmental change that produced the type now known as African.
Examine the differences between Asians and Africans and you get the
story. Curly hair to aid in heat dissipation. Large buttock muscles to
aid in chasing fast prey on the ground. Tallness to see over the grass
for predator avoidance and food identification. Large, fleshy nose and
lips to aid in heat dissipation. Larger male sex organs to penetrate
more fully for improved fertility; needed because the larger buttocks
get in the way. More active sweat glands to dissipate heat. Remember,
black skin protects from sun radiation, but increases heat absorbed by
the body. The head is especially vulnerable to heat because of brain
temperature limitations. Curly can absorb radiation heat without
transmitting it to the skull, while providing extra protection for the
perspiring scalp. Don't forget that physical characteristics are also
affected by selection for sexual attractiveness as well as by
environmental concerns. Now we have two types. And the new adaptations
have expanded the food supply, so the new African population has the
opportunity to grow. The rain forest is still a more hospitable
environment than the grass, so it can be expected that once the African
population grows large enough to overpower the forest dwellers, they
will in turn put the Asians out of the forest. Now these Asians must
adapt or die. They must also move away from the likely productive
grasslands being occupied by the Africans, since a state of war exists
and Asians are outnumbered. Some groups will become Africanized if they
continue to dwell on the plains. Others will look for a new rain
forest, and eventually find one in East Asia. Both types will
eventually populate the viable land areas between the new Asian
settlement and the African settlements. This creates a transitional
gradient of mixed race between the two geographical areas. If you
examine the data, this is in agreement to it. The Europeans are
derived from peoples with a various mixture of both racial types, Asian
and African. Light features are revered in most dark-skinned
populations, since they are rare. One reason for this rarity is that
tropical environments disfavor the survival of light-skinned
individuals. Once humans adapted to living in colder, shadier,
environments, the potential for survival increases for light-skinned
individuals. Mountains in central Asia present such a climate, and when
these areas become populated, migration to other suitable environments
can progress from necessity. Of course, these light-skinned groups will
not migrate back to tropical areas, which are likely to be
overpopulated anyway. They spread north into Europe. Nordic groups
appear to have more Asian ancestry when compared to the Mediterranean
groups: straighter hair, proportionally larger calf muscles, etc.
Adaptations to cold weather can confuse understanding of this,
somewhat.
Cold weather favors large bodies, long nasal passages for warming
inhaled air, thinner facial features, as heat dissipation is not so
important in this environment. Looks like climate logically explains a
lot. Now we need to test this theory. Your input will be appreciated.
