Where to begin.

I admire the families of animal groups and since mankind is a form of animal, I believe we could learn from our surrounding nature.
My first example is of the wolf. The wolf is a community animal. They live in communities and population is kept down since only one woman is chosen to be the alpha female. The other females do not give birth, but nuture the young of the alpha female. The females of the community even lactate to help feed the young. Males do not fight to kill for domination, although they prove their worth to the alpha female by combat. Wolves remain in their own territory and community.
This is an excellent example of population control and nuturing.
Should every female be expected to give birth, or are there other roles a female can do to help the community?
