The mayans are gone and if they were so great why was the language largely replaced when the aristocratic spanish empire, ruled by a small but elite group of lombard & gothic descendants (i.e. nordics), conquered them. The South American and Mexican population is a melting pot, they are mixed with all races. I hope you know that even if evolution is true that races still aren't equal since intelligence is inherited, it would a simple mathematical fact that races aren't equal. Even the rare occasions when subhuman races have an intelligent offspring, it is even rarer that it produces a next generation offspring of comparable intelligence.
