        I noticed that there are, definitely, two types of Homo, the eastern one, and the western one. I mean, this is obvious, eastern people are shorter and have round heads, while western people are longer, and have more narrow faces.
        I also noticed that African people definitely belong to the western type. Now, how can that be? Per standard view eastern type arose from Africa. I don't think that's true.
        The only logical explanation should be that Homo arose from Euroasia. There we already had two types, Asian type is from around China, the western type from the opposite end of Euroasia, from Europe. Africa was completely separated from Euroasia, both, physically and in population. So, in Africa we had Australopithecus. People in Euroasia, because of its developed coastline, were very much in contact with sea, while African Australopithecines were more inland. People in Euroasia developed proper language (unlike Australopithecines), while people in Africa lagged behind a lot in language. When Euroasian population started to produce tools, the western type spread into Africa, extincted Australopithecines, and this is how we got today's situation.
        The difference between Africa and Euroasia (the interlocking between humans and animals) is stunning.
        This is Euroasia:

        In other words, African people were white in Euroasia, and then turned black in Africa, and not the other way around. Lol, our skin even has the ability to turn brown if exposed to too much sun, it doesn't have the ability to turn white, if there isn't a sun.

 When trying to find out the place of the origin, a good method is to find
the least related subgoroups or individuals. Usually they are found at or
near the place of the origin. In che case of Homo sapiens that place is in
southern Africa.
 A large part of the differences between the African and other populations
can be understood as adaptations to a colder climate. Likewise the
differences between European and many Asian populations can be understood
as adaptations to even colder climate.

  I don't get the first part of your answer.

Strange. I don't see anything unclear in it.

The second part you are right, there are temperature adaptations. But, in which direction, this isn't clear at all. I definitely agree that East Asian people are adapted to the coldest climate.

Sweating is an obvious adaptation to high temperatures. It is found in all
humans but not much in other animals.
