On Monday (Jan 21st, 2013), America will celebrate the life of Reverend Martin Luther King Jr.- a man dedicated to the fact that all men are created equal and should be treated that way. Americans owe humble respect to Reverend King for his dedication (that led to his assassination) to this noble ideal.
I find it extremely interesting that many naturalists promote King's idea of human equality. But is that promotion compatible with naturalism? Human equality is a Judeo-Christian concept that is foreign to any worldview that must rely upon naturalistic evolution to explain the existence of the human race. Here's what I mean:
Survival of the Fittest
One of the major pillars of naturalistic, evolution is "survival of the fittest". This simply means that the lifeforms most fit for a certain environment will propagate their offspring into the next generation; lifeforms that possess any feature that inhibits their survival, will eventually die off. Value is assigned based on this survivability.
Notice the superlative language of the pillar- "fittest". In order for a superlative to exist, there must exist another that it is superlative when compared to. If humans are the result of "survival of the fittest" and we are not the end of evolution (mutations are still taking place today, so I guess we're not), then some members of our species are superlative to others. The genes of the superlative humans will survive into the future.
