If you believe in evolution you will also have to believe that different human races exist to the lefty evolution believers here.
Research indicates that the concept of “five races” does, to an extent, describe the way human populations are distributed among the continents—but the lines between races are much more blurred than ancestry testing companies would have us believe (Figure 1B).
"What the genetics shows is that mixture and displacement have happened again and again and that our pictures of past ‘racial structures’ are almost always wrong, says David Reich, a Harvard University paleogeneticist whose new book on the subject is called Who We Are and How We Got Here. There are no fixed traits associated with specific geographic locations, Reich says, because as often as isolation has created differences among populations, migration and mixing have blurred or erased them.
A landmark 2002 study by Stanford scientists examined the question of human diversity by looking at the distribution across seven major geographical regions of 4,000 alleles. Alleles are the different “flavors” of a gene. For instance, all humans have the same genes that code for hair: the different alleles are why hair comes in all types of colors and textures.
In the Stanford study, over 92% of alleles were found in two or more regions, and almost half of the alleles studied were present in all seven major geographical regions. The observation that the vast majority of the alleles were shared over multiple regions, or even throughout the entire world, points to the fundamental similarity of all people around the world—an idea that has been supported by many other studies.
If separate racial or ethnic groups actually existed, we would expect to find “trademark” alleles and other genetic features that are characteristic of a single group but not present in any others. However, the 2002 Stanford study found that only 7.4% of over 4000 alleles were specific to one geographical region. Furthermore, even when region-specific alleles did appear, they only occurred in about 1% of the people from that region—hardly enough to be any kind of trademark. Thus, there is no evidence that the groups we commonly call “races” have distinct, unifying genetic identities. In fact, there is ample variation within races."
Ultimately, there is so much ambiguity between the races, and so much variation within them, that two people of European descent may be more genetically similar to an Asian person than they are to each other.
There are no fixed traits associated with specific geographic locations because as often as isolation has created differences among populations, migration and mixing have blurred or erased them.
I've noticed that people who spread this race thing always fail to specify how many races they believe exist and what those might be. This social construct, in my opinion, ignores the blurred biological divisions between different types of groups spread across the world. It's very hard to enumerate the biological divisions, just like the colors on a spectrum, or at which point does it get cold or warm in the temperature.
There is no scientific evidence that links different races to intelligence. It might exist, but we do not have the evidence for it at the moment, and would rather not waste my time talking about it.
