My belief is that if we were completely unsocialized we'd be acting like rabbits.We're actually not. We're technically at a half-way point, biologically, between monogamous and polygamous. Basically, we're at a point where someone people will just prefer one or the other, but the norm has been some sort of polygamy, and while strict or serial monogamy can work for some but it certainly isn't for everyone.
