I think biologically we have an inherent need to protect our organism - our self - from all external threats whether from macroscopic species likes apes and dinosaurs or microscopic ones like bacteria and viruses.
Ironically, exposure to both of these, with some limitations, can help provide less friction in the long run whether it is culturally(macroscopic) by getting along with others or whether it is through a stable immune system(microscopic).
So yes, we are inherently self-protective, but external exposure will change that. That being said, even our baseline levels of self-protectiveness differ, the biggest difference appearing in gender. Women clearly have a different baseline level reaction to external stimuli that is different from their own, but it's not as simple as yes/no.
