"its the wanton need to reproduce, not to gather"

Yea, that would generally fall under the effect of Bio-survival, more so even than 'gathering'.

"most creatures don't really gather at all"

You're right, I think it's mostly the habit of mammals. From what I understand most things involving any form of community(even if it's "Selfish"-- you could almost call reptiles selfish by nature which is what made me relate it to 'Oral' tendancies) are generally considered the foot of mammals, which I guess would make them "anal".

Selfish and anal.
