What is an example of a random genetic mutation in humans that has proven to be beneficial?
Well, basic natural selection states that random mutations, while usually negative, can sometimes be positive and will help the creature successfully reproduce. We atrribute this to how we ourselves became our species. We classify ourselves as animals, and genetically speaking, we still show many mutations, approximately ~2.5×10−8 mutations per base per generation. With approximately 100 billion humans ever having lived on earth, shouldn't we have seen or heard of at least 1 reported beneficial mutation?
Now of course it would be hard to document someone with a beneficial mutation 20,000 years ago, but what about in the past 500 years?
So have you ever heard of a positive mutation that has been seen in humans? If yes, what was it?
