yeah but what happens if the climate/ecosystem goes back to the way it was before? then they'll change back and nothing will come from the change...
that is also evolution
anyways we cant prove evolutions existence because we haven't ever seen it happen, we have seen adaptation but not full scale evolution from one species to another
I would argue that we have seen full scale evolution in domesticated dogs. I'm fairly sure that this
won't interbreed with this:
another example being the development of bacteria that are resistant to antibiotics.
