Most every animal species? Fun fact, they nearly all, at an individual level, die very quickly.
Sorry to say that as a human, you’re hard wired to engage with nearly every being on this planet as though it is sentient and beloved, because we’re a bunch of dumbasses.
Most animal species are social, only a minority are solitary. And definitely most animals are social, as prosocial species have vastly larger populations that solitary ones.
And now you won't be able to stand behind your claim of "most every animal species live their lives in solitude".
You are right we're somewhat hardwired to engage other animals, especially mammals, but not because we're "dumbasses", but because humans are an eusocial species and puppies look like babies, because they are (a lot of mammal offspring share similar qualities such as the head and especially eyes being disproportionately large compared to the body.)
But yeah, youre definitely wrong about most animal species being solitary. Simply not true.
