What’s YEC explanation for the emergence of races?

I believe that genetic code was weakend during the 'evolution/creation' of the human race. Strands of DNA evenutally wear out and breakdown due to years of breeding and illnesses. During 'evolution' this would explain the diversity of language and skin tone. Some people claim that latin was the first language ever, while others say Greek was. Depending on religous beliefs, peoples opinions would of course be different. If 'god' created the human race, then he probably wouldn't have made different races. DNA has taken large strides throughout history and have been altered, broken down, examined and put back together to try and create a better human. Hence creating the world we live in today, but hey, Im only 16, I haven't lived forever...And trust me, I don't think anyone will...
