Wide scale racism is one of the consequences of the hypothesis of macroevolution. All humans (including those of subSahara African descent) are extremely similar in genetic makeup.Except that creationists are always so eager to assure us that they accept microevolution - just not macroevolution. And yet, this mutation is a textbook example of microevolution, a process which creationists insist that they fully recognize as existing.
What's ironic about all this is, liberals are happy to accept the truth of macroevolution yet blanch when evidence of microevolution having occurred rears its ugly head.
You have it backwards. All humans are the result of mini-mini-microevolution, and pretty small potatoes at that.
Real microevolution (on an evolutionary scale) results in larger (subspecies) changes, and macroevolution even larger (species and genus) changes. Human races are not even close to subspecies.
I have found that the more people study evolution and human races, the less racism there is because they actually understand the basis for both classic and genetic racial traits.
Racists make it up as they go, based on ignorance and prejudice. We have seen the results of that for centuries. But that is not the result of the theory of evolution (or as you put it, the "hypothesis of macroevolution"). Rather, that is the misapplication of the theory of evolution.
Don't the various races share something like 99 percent of their genes?
