Where do you think lactose tolerance came from? Oh right, random genetic mutations and last time I checked lactose tolerance is not a disability. That's why your statement is dumb.
WTF dude, you keep putting words into my mouth that I definitely didn't say and then you respond to those words, it's like you're having some weird conversation with a person that doesn't exist.
I never said Lactose intolerance is a disability. I said genetic mutations cause disabilities, I did not say all genetic mutations cause disabilities. Most genetic mutations are completely harmless and go by unnoticed, many genes are 'inactive'.
Survival of the fittest simply means those that are able to survive do. These days everybody is able to survive.
Yes, and many species have been able to be more fit for survival because of random mutations. So basically the opposite of your entire claim.
No, not the opposite of my claim, exactly the same thing, part of the same system, the same mechanisms in action, FML. Survival of the fittest is what causes positive mutations to survive whilst negative mutations don't survive.
