@Ferrovore Assuming you're talking about wolf 'pack hierachy' here and not blood-types:
What's still interesting to me about the whole thing is twofold:
1. The standard observation I've heard others make about "this reflects more on human behavior than wolf behavior, because humans are the ones doing the interpretation", which also helps explain why folks growing up in human society keep finding it resonant in fiction...
BUT ALSO:
@Ferrovore
2. The way I understand it, the original flawed research that showed enforced dynamics, dominance challenges, etc, was based on animals in captivity, while wolves in the wild turn out to live in fairly simple nuclear family units. That basically means that what we see about Alphas/Betas/etc could be taken as an example of (admittedly forced) 'found family' organization. And this actually maps to the sorts of packs you usually see when it comes to fiction and animal-people culture.
