I think causation is reversed. The goal of studies like these is not to dictate how we should behave, but to inform us how we might.
Should we use our feces to mark territory? Probably not, but when the concept of marking territory is as pervasive as it is then maybe it's worth considering how we would like to handle it to avoid falling back to feces.
Again, pervasiveness does not magically make it valid.
Many animals eat feces, that's extremely pervasive. It's an intrinsic part of the ecosystem. It's really hard to overstate how important poop from other animals is. Doesn't mean I should be cooking it for dinner.
Applying any behavior as having any meaning at all to humans, whether it be wolves or lobsters, other than that we should respect it, is complete nonsense.
There are no lessons to learn about how we should structure our workspace or allocate tax dollars by watching how jellyfish or seasnails live, any claim otherwise is merely ideological projection and creative license.
