ah. admittedly a weaker point in my argumentation, perhaps as a result of my racial bias.
but I think I can find a rebuttal to that.
these coyotes and badgers joining together to find food, would be the same as tribe A and tribe B working together in an agreement to help each other during the winter. More modern, country A and country B signing a non-aggression pact.
When these tribes would share the same territory outside of their common goal, would intermarry, would accept a tribal leader of one tribe as legitimate,... then we could speak of an in group.
As your example deals with two different species who cannot possibly be the same ingroup, the following example woud be closer:

(dolphins and humans working together to catch fish).
so I would see it more as a cooperation, to each benefit, but not without the vanishing of the in group out group distinction. Just as the coyote and the badger kill and eat other species, so they work together in this prairie ecosystem.
As I said,between different species exist different sexual strategies, familial structures, instincts,...
as long as reproduction and survival are safe, there exists a ground for cooperation. this symbiotic relationship between tribe A and tribe B, between dolphin and fishermen, between badger and coyote is as such in line with natural morality.
what I meant with an unnatural value-based, and fake in-group, would be modern europe.
they promote third world aid (allocate resources without getting anthing in return), open the borders (abandon their territorial claim), are positive towards racemixing (genetic dilution),...
so a false in group is created, by blurring the distinction between native genetic germans and negroes, arabs,... and masking this biological failure with artificial ideas of civil nationalism, humanism, diversity,....
