I understand the concept of Natural Selection as such: There are two animals of the same species, slightly different - one whose "slight difference" is more helpful to its existence in current conditions survives, the other dies and never produces offspring. Therefore, most of the next generation of the species are more like the surviving animal.
If there're a bunch of monkeys, and a bunch of them no longer has a tail, perhaps a predator doesn't have a tail to grab on to when they catch them or something so they can avoid the predator better or something. The other monkeys get eaten, humanlike ones don't and can keep reproducing on ground, whereas the offspring of the other ones are forced to sit high on trees. Right?
So here's my question: how do you apply this to modern humans? Our survival and offspring rate no longer depends on these little things since our technology allows us to not need any more biological advantage to safely live and have sex. In fact, any deviation is likely to be taken as an abnormality and unattractive to the members of the opposite sex.
Does that mean we're done evolving as a species? Or how do we justify further evolution given the natural selection.
its because we've gained control over our environment, including predators but i don't think we have stopped evolving due to natural selection. natural selection will just play an extremely small role for now and will take longer than ever.
