This sorta lends weight to my hunch from watching hours of YouTube videos that mammalian toddlers have to learn to differentiate by species. Cross-species friendships between mammals from toddler to adult happen all the time in human-controlled environments, only in the wild is this more or less prohibited owing to adult animal intervention. Perhaps we can learn something about the reproduction of racial prejudice from this...

Wow. Your idea really inspired a few new thoughts in me. Is there any good books that talk in-depth about cross-species mammalian friendships?

Any idea about mammalian->other kingdoms?
