Demographic Growth: The Basics

John Hawks over at the University of Wisconsin, Madison posted a piece that caught my eye on the basics of demographic growth.

In it he reviews the basics of growth: linear versus geometric and instantaneous growth, and what that means for models of human population growth. He writes:
You get the idea: this bank problem is very much like our problem reconstructing ancient demography in human populations. When we consider genetic variation, what we observe in today's genes was affected not only by the population sizes at the signposts that we observed in the past, but by every point in between.
