    The Europeans see all Chinese as black haired with small noses, probable Denisovan features? Would the possibility of neanderthals having retained their thick body hair, instead of having manufactured clothing like sapiens, be the influencing factor on their body shape?
    Perhaps the only reason sapiens made clothing is because we were the first animals to lose their hair and the only way or African ancestors could migrate north at a rate faster than evolving or hair back was to wear clothes. In turn we didn't need to regrow or fur?

      It’s not a Tall vs. Short hypothesis. It’s based on the ratio of body mass to body surface area. High body surface sheds heat (advantageous in hot climates). Low surface area conserves heat (advantageous in cold climates). This ratio is entirely independent of height.

    • @happytrees4734
      @happytrees4734 3 года назад

      “Tall” has nothing to do with cold/hot climate adaptation. It’s about the ratio of body surface area to body mass. High surface area ratio sheds heat more efficiently. Low surface area ratio conserves heat. Also, there will always be outlier populations compared to the aggregate. The aggregate of all African populations has a much higher surface area to mass ratio than the aggregate of all European populations.

    Is it possible that modern humans of 40,000-50,000 years ago had greater cultural adaptability and occupied niches sooner than Neanderthals in warming periods? When they expanded out of their ice age refuges, we were already there and we drove them to extinction by taking their range away. It appears that modern humans were restricted to the warmer parts of Eurasia until about 50,000 years ago. Moving into colder areas had to wait until they had the culture and technology to survive there. Before that, they had no advantage and were unable to invade the Neanderthal areas. Asian Homo Erectus may have survived as long as they did for the same reason.

    The craniofacial morphology of modern humans is due to self domestication. It coheres with the cranial morphology found in all domesticated species, and is a result of premature separation from the mother.

    • @search895
      @search895 3 года назад

      I dont think premature separation from the mother has something to do. Apes and specially us have really large infancies. Also self domestication occurs in other free species such as bonobos. In our case, our notorious neotenia probably has to do with our helplessness at birth due to a need to get out of the bipedal narrow pelvis of our mothers before our brains and skulls get too big.

    • @sjobang
      @sjobang 3 года назад

      @@search895 You seem to have read Richard Wranghams book about the subject. It's highly politicized science though, and there is nothing to indicate that bonobos used to have larger brains. On the contrary it's worth wile noting that all big brained animals spend years fostering one or two offspring at a time. Near the other end of that scale are animals like the pacific oyster (with hardly a brain at all), which spreads up to 300 million eggs into the currents each year, and there is an obvious connection in nature between quality and quantity, investment and output, or however one prefers to put it. Increased care for the offspring has demanded bigger brains, up through the evolution, and there is a logic to this which can no longer be ignored. The human brain is already 15% smaller than it used to be, the average age of puberty has been reduced by five years over the past 250 years alone, and there is a very ugly truth to this that the elite wants to hide.

Do my African friends in Canada suffer from nose dryness? I want to know. As a narrow-nosed person ;) did I get extreme moisture complications when living in wet South Asia?
