    Evolution by Cultural Changes

    Culture may trigger rapid evolution of various human features. A recent study of a tribe from the Brazilian rain forest proved this. Evolution is often thought to be driven by environmental factors, including climate, but cultural factors can have profound effects on behavior and possibly lead to evolutionary changes.
    Scientists analyzed genetic, climate, geographic and physical traits of 1203 members of six South American tribes in the Amazon. One group had significantly diverged from the others in terms of their morphology, or shape, possessing larger heads, taller and narrower faces and broader noses.
    These characteristics evolved in approximately 1500 years after they split from a sister group, called the Kayapo, at a rate that was almost 4 times faster than comparable rates of change seen in other tribes.
    The researchers(geneticists from Brazil's Federal University of the Rio Grande do Sul) verified that the Xavante experienced a remarkable pace of morphological evolution.

    From Science on MSNBC.com. 12-19-2011

    This may have some relevancy as to why and how the ancient Nordic peoples evolved so rapidly and were so profoundly different from other peoples at that time.

    I've long suspected that culture influences genetics more than people think it does (the environment, though important, is given too much importance in attempting to explain genetic diversity in academia). There is strong evidence; the Hindu caste system, Confucian personality conformity, Jewish intelligence (last chapter of "10,000 Year Explosion"), European mental/physical features ... it seems all groups of people have their own unique genetically selected mental/physical traits- selected for solely because of their unique culture.

    Here's an interesting lecture by Professor MacDonald about how the culture of the ancient Germanic tribes was different than other tribes and lead to evolution for a unique type of physical features and personality . (last 30 minutes)

    Our culture is healthiest when we not only understand but also get back to the values that made us who we are (valuing; monogamy, kids, family values, work ethic, modesty, mental/physical health - it's really surprising how different other cultures views on these core areas actually are even from ancient to modern times).

    Sounds realistic enough.

    It explains how negroes have evolved towards popping out 20 kids with 7 different "baby daddys", because their culture developed in the African jungle where everyone can eat the low-hanging tropical fruit (nature's version of the welfare system) and there's no need to have families with both parents.

Havent got to the "hail the jews for their sociopathic traits" chapter, and I'm not sure I'll ever, because reading it made me almost puke more than once so far. Imho its goal is to confirm Jewish supremacy and that they're the chosen ones to bring salvation and civilisation to mankind with pseudo-scientific explanations.


    But that aside, it's actually quite obvious that culture plays a role in selection, and selection has of course an effect on the genetic / physical traits prevailing within a population. What's maybe even more interesting in this was the Russian Fox experiment, which showed that we dont know much about how genes and alleles really function, despite that we can sequence them meanwhile. The pure selection for tameness in that experiment changed the physical and phenotypical appearance of the foxes way more than was expected, and even imaginable. If it had continued, it probably had produced a new subspecies of foxes. So the cultural preference for this or that character trait also affects physical traits as physical traits affect character traits.

    One important factor though is isolation, so as to reduce the variance and to generate a prevailing set of traits from which to specialise further.

    During the last ~1000 years, cultural preference for certain traits has already been replaced by other "ideals" brought by christianity, and instead of looking at Amazonas Indians, we better have a look on the reduction of quality this already had for us. The currently prevailing ideology of multikult (= no culture at all) overrides cultural selection though and will probably become the death push for our people. All people for that matter, since it aims to eradicate uniqueness.
    Ein Leben ist nichts, deine Sprosse sind alles
    Aller Sturm nimmt nichts, weil dein Wurzelgriff zu stark ist
    und endet meine Frist, weiss ich dass du noch da bist
    Gefürchtet von der Zeit, mein Baum, mein Stamm in Ewigkeit

    That's actually not at all the impression I got when reading the book. He even talks about how Sub-Saharan Africans have trouble saving and planning and goes on to say that it is probably the result of genetic reasons (that's the most politically incorrect statement I've heard from a mainstream academic book in years). I also thought the Jewish chapter was unbiased, he was just pointing out that they had recently (last thousand years) selected traits (such as myopia) that had increased their average intelligence. If you're afraid that people might decide that Jews deserve to have total control of media/banking/politics/university because of their higher average intelligence- there's plenty of books that people can read about that ('Culture of Critique' 'The Israel Lobby and US Foreign Policy' '200 Years Together' ).

    That was a great section in the book "10,000 Year Explosion". It makes me wonder if Hans FK Guenther could be proven correct in pointing out that different sub-races have on average different mean personality types.

    One important factor though is isolation, so as to reduce the variance and to generate a prevailing set of traits from which to specialise further.

    During the last ~1000 years, cultural preference for certain traits has already been replaced by other "ideals" brought by christianity, and instead of looking at Amazonas Indians, we better have a look on the reduction of quality this already had for us.

    Great point. Both marriage isolation and selection by birth rate differentials are vital to our survival. (both of those ideas are held together by culture)
