Beyond my competence, Harry. > In the same way, I wonder whether it wasn't the case that harsh conditions > led to the production of "high quality" children, but rather that "low > quality" children simply didn't survive. I'm sure it was something like that. I recall an Alaskan anthropologist getting Holy Hell from his fellows because he suggested that, historically, Alaskan Athapaskan women would refuse to love their children because they were certain that they would die within their first year or two of infancy. It was a hard life. The physically inept children would probably die early, the mentally slower somewhat later. Those that were physically and mentally ept would probably survive, but there were no guarantees. > Also, while larger families are more draining, is this more than > compensated by the advantages of a large family in later years? In medieval times, and even into recent times among medieval people, there were ever so many children. One of my aunts from central Europe had 17 or 18, 12 or 13 of whom survived. You had a great number of kids because many of them would die, and you needed those who survived to help out with the work. Because so many kids died, population would not increase much despite a high birth rate. > If the children continually left the nest as they got older, any advantage > to the parents might be lost.

In traditional society, as in medieval times or in the Arctic, kids didn't leave the nest. They stayed around and became the next generation, whose numbers didn't exceed the previous generation by very much if at all because of high death rates. > Perhaps your experience can give us a clue. I would never argue that Aboriginal Canadians of the far north, like the Dene or the Inuit, are genetically superior, in whatever sense, because the strongest and smatest of them managed to survive the harsh conditions under which they lived. However, I would argue that they had to be strong and clever to survive in the environment in which they lived. Probably, they carried the genes of those who were not so smart and not so strong along with them, and in the new conditions under which the Inuit and Dene now live, kids who might not have survived before are surviving and multiplying now. What I find interesting is that people, probably quite unconsciously, seem to meet whatever situation they are in. If they need a lot of kids because only a few will survive, they produce them expecting many to die. If, as now, they are living on the edge of affordability and need two incomes, they'll have few kids because they don't need them. I think its an almost unconcious, visceral response, given the circumstances.
