Given that mutation occur because there is a change in the structure of DNA, in animals, for instance the predominant species who may have mutations that help them survive in the wild world, those could be the ones who pass it on to their offspring. In my mind mutations are only transfer between generations if there is an actual benefit that lead to that species living longer, survive, protect or even hide better.
But with humans, how mutations work? We are not been chased down, eaten by predators? In that scenario, where everyone’s offspring gets a copy of a DNA from their parents, how we as humans have developed through the centuries, how is DNA mutations are propagated more so that it takes over and then more people are born with that mutation? For example, babies being born without wisdom teeth, smaller pinkie toe.
In the scenario of wisdom teeth, i heard that humans used to chew raw meet or something like that and thus we used those wisdom teeth more, but how it became so that now babies are being born without it?
I hope i made myself understand, I’m wiring down this before going to bed and I could go to sleep before looking for an answer, and my brain is not braining atm.
