There were 4 children, and one died. I have often wondered why the world's homo sapien population did not grow faster during the period 200,000 BC to 10,000 BC. In his book Extinct Humans, Ian Tattersall has argued that fully modern homo sapiens took shape around 200,000 BC and left Africa around 150,000 BC.
http://www.amazon.com/Extinct-Humans-Ian-Tattersall/dp/08133...The growth of the population was very slow. Someone suggested that at their peak there were 100 million bison worldwide, but it seems to have taken most of human history to catch up with the bison -- we seem to have hit that number only when we began agriculture. As late as the year 1300, the historian Fernand Braudel estimates a world wide population of only 500 million people. We became one of the most successful species in the history of the planet, so why wasn't there faster growth, for such a long time?
That question interests me, so it also interests me that a family, living alone, with fanatic Christian fundamentalist beliefs and no access to contraceptives, still only ends up having 3 surviving children -- not a whole lot in excess of the replacement rate.
Something similar to this must have been going on for many thousands of years.
