Subject: HACNS1 gene; huge mistakes of logic by NOVA "Decoding Neanderthals" #188 Rockthrowing theory book
I do not recall the biology term, when one species is invaded by a similar species and where the one species is extincted and then the invading species begins to evolve genes that help it survive the new territory and environment that it finds itself. These new genes identical in large part to the genes that the extincted species carried to ward off bad health.
Now some biologists would be incorrect to assume the two species interbreeded as to how the invading species received those immunology genes. But that is a false assumption and rather, the better hypothesis is that the environment has a tendency for the new invading species to mutate to those better immunology genes.
So for example, Homo sapiens invades Europe where the different species of Homo neanderthal lives. They are two different species and cannot interbreed. The Homo sapiens is superior in rock throwing genes of HACNS1, and in almost all engagements of fighting between sapiens and neanderthal leaves the superior throwing in favor of sapiens.
Within 10,000 years, every neanderthal is extincted from Europe. And within 10,000 years is a long enough period of time for that 1 to 3 percent of genes to become acclimated to the new environment of Europe with genes to help in immunology. Not because of any interbreeding, but rather, because natural small mutations would have constantly occurred in that 10,000 years to make the invaders acclimatized.
I have some evidence from the bubonic plague that hit Europe in the last 2,000 years where some groups of Europeans had a mutated gene that they were immune to the bubonic plague, and when the plague struck at different time periods, these immune genes flourished, so that Europe was rather immune to the devastation of bubonic plague to a 4% or more of all the European people. So the bubonic plague shows us how in 2,000 years that a large population can have mutations to where 4% of that population has immune genes. And since in the NOVA show, the one scientist pointed out that Tuscany Italy seemed to be the center to where Homo sapiens mutated into this 4% immunology.
Another piece of evidence is the actual extinction of the Neanderthal. Many Neanderthal lived near the Middle East, not Tuscany Italy, so that one would think that if interbreeding were the answer, that the Middle East would have the largest percentage. And if I remember correctly the last hold-out of the Neanderthal species was in Spain, the caves of Spain and Spain is far closer to Tuscany than Tuscany is to the where Africans migrated into Middle East. What that indicates is that interbreeding was not the means of acquiring the immunology genes but rather that Homo sapiens had a permanent large settlement in Tuscany and where they were mutating to a 4% immunology gene.
What is that term where the environment is a pressure on the mutation of genes of similar species to converge to a similar mutation of benefit? For example, if you moved a lot of black Africans up North in Europe where they stayed for 10,000 years and only bred among themselves, that after 10,000 years their skin color would not be as black as their cousins in Africa. And the reason is obvious in that the environment selects for a lighter skin color to get more vitamin D as a health benefit since the Sun is not as bright in Europe as it is in Africa.
