> The way this graph [of surviving population size over age] has been constructed, a straight line going diagonally downward is neutral, or no aging at all.
Um, no. They introduced age as probability of dying within that context. Therefore a constant age would produce a population size that shrinks exponentially, but never reaches the zero line, just like with radioactive isotopes' constant decay rate.
