RACISM: White supremacists believe in genetic ‘purity’. Science shows no such thing exists

Science does not support the idea of pure races with ancient origins. In the past few years, genetic sequencing of ancient and modern humans and related species has given us a flood of new information about how human populations have evolved.             

The evidence reveals a history of ongoing genetic mingling, due to interbreeding between different populations and even species. Humans from different groups had children together, and even with Neanderthals and members of other now-extinct hominin species.

This mingling occurred constantly in the long process of human migration across the globe. Europeans inhabit one region of a large genetic continuum and are no more or less “pure” than any other population.

From Africa to the world

The genetic history of humanity begins in what we now know as Africa. The exact location (or locations) of the first anatomically modern humans is debated, but there is a consensus they lived south of the Sahara desert between 100,000 and 200,000 years ago.

A group or groups of these early humans migrated out of Africa and into the Middle East, as we now know it, some time between 50,000 and 70,000 years ago. Next, some went east into Asia while others headed west into Europe.

At some point, the wandering humans met and bred with Neanderthals. These now-extinct hominins had left Africa many thousands of years earlier.

Modern Asians and Europeans still carry genetic signatures of Neanderthals, while sub-Saharan Africans do not.

The humans that migrated east into Asia also met and bred with other extinct species of hominins, including at least two major injections of genes from a group we call Denisovans.

Early modern humans almost certainly bred with other ancient hominins as well, because interspecies breeding was likely common. The remains of a girl with a Neanderthal mother and Denisovan father have recently been discovered. Another recent study has shown some Neanderthals too carried traces of human DNA.

Genetic diversity leads to greater fitness

Genetic diversity, as measured by a metric called heterozygosity, decreases with geographic distance from Africa. Higher heterozygosity is generally associated with greater genetic fitness for survival.

From this perspective it could be argued that, when the humans who walked away from Africa lost genetic diversity through living in small groups, they also lost genetic fitness. By the same argument, interbreeding between populations increases fitness.

In fact, Europeans probably benefited from picking up some Neanderthal DNA: these genes are thought to have diversified their immune systems and may have contributed to their lighter pigmentation.

Humans who migrated west into Europe continued to meet and breed with other human populations.

Another wave of humans from what we call Anatolia (roughly modern-day Turkey) followed the initial spread of humans into Europe. The Yamnaya population from what we now know as the Russian steppe migrated west into Europe between 3,000 and 5,000 years ago. In fact, little genetic trace remains of the first human inhabitants of Europe, as they were continually supplanted by others.

Even the Roman civilisation, considered to be one of the historical foundations of European identity, was home to great genetic variety. A recent study looked at the genomes of 127 people from 29 sites across the past 10,000 years. It found an initial wave of hunter-gatherers had been supplanted by an Anatolian population, and during the age of Imperial Rome (27 BC to 300 AD) there were significant introductions of genes from what is now Iran and the eastern Mediterranean.

Even Vikings were diverse

Blonde-haired, blue-eyed northern Europeans are considered by many white supremacists as the ideal of racial purity. They are epitomised historically by the Vikings.

However, the reality was different. A recent study of 442 human genomes from archaeological sites across Europe and Greenland found substantial ancestry from elsewhere in Europe entering Scandinavia during the Viking Age. In fact, Vikings were more likely to have dark hair than modern Scandinavians.

In short, the idea of a pure white race has no basis in genetics. Lightly pigmented skin, hair and eyes are simply an adaptation to northern European climates (and represent an inferior adaptation in equatorial regions). These features exist in a background of countless other genetic influences borrowed from many populations, old and new.

    Reminder
    Hitler and his Nazi fantasy !
    White Aryan race ….blue eyes blond hair !

    Fast forward today
    Dye hair
    Wear contact lenses

    Watching colour TV today.
    Colourful is beautiful !

    Cross breeds and half breeds way forward !

    Survival of the most diverse of the species
    Darwin re-incarnate !

      Bleach skin like Vybz Kartel. He had to bleach his skin to get record deals with the American record labels.

      • kamtanblog  On October 1, 2020 at 2:32 pm

        Really!
        Idiot !
        Not aware of Vybz Kartel case !

        Don’t consider myself “white”…
        Am person of colour (olive skin) and proud
        of it ! Most are confused with Natiomalism
        V Racism …politicians guilty as charged !
        They use both to win votes !

        Sheep then go and elect jackasses !

        Compulsory voting a must for democracy
        to survive !

        My take

        Vybz Kartel is the most famous man in de world!

        Me berry berry sorry my friend !
        Will have to google FMI now ….
        The new song and dance music
        (South African) Jerusalem will replace
        CorV pandemic as next big ting to hit
        the planet…go google Jerusalem
        for de music !

    It’s hypocrisy that those ABCEU countries want immigrants to work as horses for the Social Security of the same Americans who believe in a white world where brown, yellow and black people should not exist. Quite an irony. If those racists in Canada, America, Europe and Australia/NZ execute every one of us non-white people, the economic system will collapse.
    If white people don’t want us, then why did they enslave us?

    • kamtanblog  On October 1, 2020 at 2:23 pm

      Free labour !

      Slavery exists today with slave wages
      as per ERM (exchange rate mechanism)
      with USD$ as world reserve currency.
      Address the ERM issue and voila solution.

      Will fantasy money (crypto) replace USD$
      as world reserve currency ?
      Will international trade WTO recognise
      usd$ replacement ?
      Not long before questions answered
      3rd Nov 2020.

    • Dennis Albert  On October 1, 2020 at 4:02 pm

      Doesn’t America blow up entire countries who refuse to use the USD?

      • kamtanblog  On October 1, 2020 at 5:34 pm

        CIA first
        Then jackals
        Followed by military …usually in that order !

        USA is now a Russian puppet state with comrade rass-Putin pulling strings !

        Another debate aka pantomime is on way !
        More entertainment for the masses !
        Enjoy !

        Putin owns Trump? No wonder the PPP supporters are praising Trump and bashing Venezuela. Jagdeo and his friends studied in Moscow. Why would anyone want to move or study in that cultureless and boring cold country beats me.

        It was Janet Jagan’s idea to send him to
        Moscow for communistic indoctrination.
        Janet was a member of the communist party
        whilre at uni in USA where she met Cheddi and
        married him. They both returned to BG where
        they entered the political race to independance.Chedi was democratically
        elected as premier on a hap n jaut “vote for race” ticket. JFK Potus USA 🇺🇸 instructed
        Mc Milan uk PM to suspend constitution
        …black watch troops dispatched to BG
        Chedi incarcerated. Because of Janet communistic ideas (affiliations) ..USA did
        not want a communist BG post independence !

        Rest is history
        The kabaka LFSB Guyana scholar and QC
        (Queens council uk educated) replaced Chedi
        USA educated under PR ticket !

        Hope guyanese are taught it’s true history
        in schools and university UG today !
        Truth to power….
        BG colonial past best forgiven not forgotten !

        Was lucky as it all happened in my lifetime.
        Like Johnie Walker whisky “ still going strong”
        at 77 and counting. 💯?
