Biodemography: Consilience in action an introduction to a special issue of social biology

Abstract

Many evolutionary theorists have made a statement to an audience something like the following: "Your ancestors differed in many ways. Some were smart, and some were dumb. Some were pretty, and some were not. Some could sing, some could define indefinite integrals. Some could run fast, and some could grow turnips. But one thing they all did—the one thing they definitely shared in common was that every single one of your direct ancestors, without exception, successfully made babies."
