If you're the Hairy Gorilla-type that gets selected against, in the Human/non-jungle World, you'd better get into the Jungle where you ARE the 'fittest' and can possibly pass on your genes - anyway! -
-- even if your kids come out as Hairy Gorilla-types.
But -- If the girls ain't yo' species -- They're probably gonna be sterile, or your kids will be, or some weird kind o' Hybrid.
-Eh? And, she better be willing! No Orangutan Rapes allowed!
