According to Charles Darwin's theory of nature selection, the specie
adapt to the environment, and the species evolution is thanks to those characteristics
that allow the adaption process.
Now, the racism in the human specie is all the
opposite of this statement; It does not allow a better adaption process because
creates hostility between people, dismiss our genes variability and in a no
direct way, forces us to reproduce with our relatives because the circle of the
reproduction is smaller according to the pass of the time.
Based on this, i think that racism is an evolution failure.
