You still haven’t defined “levels” for us.
Do you mean trophic levels? As in animal eats animal that eats plants, vs animal eats animal that eats animal that eats plants? The ocean has many more such examples than land.
Do you mean some sort of altruistic level? As in, humans chose not to eat animals because they do have to, so some other omnivorous animal might “choose” out of animal altruism, to skip eating another animal and gorging up on plants instead as a choice? That’s an easy one to answer, none. But really only kinda because I wrote the question so sarcastically, really.
Are you equation some sort of “performs tricks”-based animal intelligence with human altruism, or the development of such? See above answer.
You will have to define levels better. You may have a very bad definition of “levels”. That makes any answer we can give unsatisfactory to you.
