S Boyd Eaton in the book Stone Age Health Programme describes the care
women go to avoid having children too close together, and also the
consequences of doing so. The idea that more children born means more
children surviving only works when you can create enough excess food
to cope in the short term, and then put those children to work
creating food in the long term.
It's actually just dawned on me that the fundamental difference is
that our neolithic food supply has *increased* with increasing
population, but for paleolithic people, and every other animal on the
planet, increasing population means *decreased* food supply.
That's really backwards, and I can't believe I didn't notice it
before...
