The perfect evolutionary mic drop! This person is making a Lamarckian argument (that we'd evolve masks if we needed them), completely missing how natural selection actually works. Evolution doesn't respond to "needs" - it's about random variations and differential survival rates over countless generations.
The reply is brilliantly pointing out this flawed reasoning by asking about shoes. By that same logic, shouldn't humans have evolved built-in shoes after thousands of years of needing foot protection? Nope, because that's not how Darwin's natural selection works!
Lamarck believed organisms could pass on acquired traits (like if you lift weights, your kids would be born stronger). Darwin showed it's actually about genetic variations being selected over time. No amount of mask-wearing will give your kids built-in N95s!
