II. How Many: A Population or a Pair?
For many years, the discussion of the number of individuals that spawned the modern human race was not accessible to science. Fossils don’t record population sizes, and the antiquity and geography of our ancestors offer little in the way of direct data on the number of individuals alive on the planet at the dawn of Homo sapiens. Only with the advent of modern genetics have scientists been able to more directly explore this question.
However, the raw genetic data say nothing about ancestral population sizes. The evolutionary conclusion that humanity arose from a large population1 rather than a pair of individuals is a consequence of the arbitrary constraints that evolutionists bring to bear on the question. Implicit in the evolutionary claims is the assumption that DNA differences can arise only via the process of copying errors (mutations) that we discussed in the previous section. In other words, under the evolutionary model, the immediate reason why you are genetically different from your parents is that you inherited DNA from each parent. However, according to evolutionary reasoning, the ultimate reason why genetic differences exist at all in the human population is mutations in the distant past.
