We can only assume several models of evolution.
But the great apes, for instance, are a separate branch with its own evolution and also among these different strains, there might be only very small groups which would evolve to become a superior species. Actually, all the great apes are critically endangered, and they might disappear too fast, long before they could evolve sufficiently.
Also dolphins and other cetaceans are part of the vulnerable and endangered groups of marine mammals. Too many animal and plant species lost their natural habitat, surroundings and with them, their opportunities, conditions and resources for surviving and evolving.
And wild animals like to be independant and free - they are neither robots, slaves or toys. Yes, if animals could speek, they would have much to complain about humans ...
