A recent discovery showed that DNA is self correcting. It fights against mutations.But you admit that genetic mutations do occur. This is obviously a fact. Evolution as a whole is not random, it is governed by a (non sentient) set of rules known as natural selection. All it takes is one positive mutation to change a population; one member of the population gains the positive mutation and then spreads it via sexual reproduction. I don’t see any problem with this at all. Is it unlikely? Yes, that’s why it takes billions of years and millions of generations to produce significant changes within a population. Over a long enough timescale, it is not unreasonable to imagine that sweeping changes may occur.
