Social science and politically correct posturing masquerading as science have "proven" that. Actual biological science -- specifically, genetics -- has shown otherwise...Science has proven there is no difference between the races.
""Analysis of genomes from around the world establishes that there is a biological basis for race, despite the official statements to the contrary of leading social science organizations. An illustration of the point is the fact that with mixed race populations, such as African Americans, geneticists can now track along an individual’s genome, and assign each segment to an African or European ancestor, an exercise that would be impossible if race did not have some basis in biological reality." -Nicholas wade, former staff writer for the Science Times (in the NYT), in Time magazine, 2014
""Humans are in many respects typical of geographically widespread mammalian species in that we are polymorphic (meaning we have “many forms”). This is what appears to us as individual differences. The bell-curve distribution of so many traits — height, weight, strength, intelligence, and the like — illustrates polymorphic traits. We are also typical among widespread mammals in being a polytypic species. Polytypic means “many types;” it is simply a fact of biological reality that not all different groups of humans are the same. Naturally occurring polytypic groups within a species are called varieties, subspecies, or races."" - Glayde Whitney, behavioral Geneticist, Florida State U., 1999 (deceased, 2002)
'as a geneticist I also know that it is simply no longer possible to ignore average genetic differences among “races.”'
'Recent genetic studies have demonstrated differences across populations not just in the genetic determinants of simple traits such as skin color, but also in more complex traits like bodily dimensions and susceptibility to diseases.'
'well-meaning people who deny the possibility of substantial biological differences among human populations are digging themselves into an indefensible position, one that will not survive the onslaught of science.'
'You will sometimes hear that any biological differences among populations are likely to be small, because humans have diverged too recently from common ancestors for substantial differences to have arisen under the pressure of natural selection. This is not true.'
