Even though almost all the differences between ethnicities is skin color there are some other biological differences although they are small. Humanity was once more than one species and we have different proportions of some of them in our DNA but one species remains. Racism is by far one of the least tenable of all human ideas. The Earth and most of the universe is between 13,000 and 14,000, closer to 14 thousand, many believe that.
Given all the other possible diversity in just our species, that of other human species and that of all the possible similar extraterrestrials there are easily many orders of magnetude diversity just phenotype wise for people like us that could happen. Even a planet with several living species of people. There are even remnants of other human species in our DNA. Some of his anologies are flawed though.
Yes there is a plentiful elotment of phenotypes within the human species. It is true that some ethnicities came before others, there are likewise smaller genotypical trees within ethnicities and different ethnicities have different strength phenotypical trees. However all people are many times more similar than the eloted diversity of the average species or at least what a species can be. The different races are due to natural selection working on different invironments.
