Every individual is different than their parents. We don’t see large scale changes from one species to another from a single generation, but from population changes over huge amounts of time.
Sometimes there’s a mutation that allows previous features to come back in an individual showing the history. Look up images of chickens with teeth.
Chickens as we know them now in a farm didn’t exist until we did our own evolutionary selection to change them to something that would have more meat on them by picking the preferred ones. Dogs are another very obvious demonstration of that. Dogs came from a now extinct ancestor of wolves, so you can carry the same fallacy, when did the wolf become a dog? It wasn’t the first ones that were lured in by a warm place and food, was it the second generation?
Evolution doesn’t have clear lines, humans just like to classify things. It’s a lot easier to do that with species separated by millions of years because the details have changed enough.
