>>11115293>Animals are sentientSentience doesn't imply that an animal has the ability of abstract thinking. It's meaning solely refers to the ability of animals to feel something, to suffer which must be divorced from the idea of an subject having an abstract conceptualization of what suffering is.
>Intelligence is requiredIt's really not. You don't have to think about regularly breathing either, do you?
>How long would you last if dropped naked in a wild expanse?If I happen to be dropped naked with some other people, chances are pretty good that I will survive for some years. Humans after all are a social species who rely on fulfilling tasks by working in groups.
