Abstract

In a recent article by Steams several approaches to the study of life history evolution were discussed including the use of quantitative genetics in the analysis of genetic correlation between life history characters. Steams readily dismisses the quantitative genetic approach to the study of fitness character variation and correlation even though many cases are documented in the literature. I suggest a reappraisal of existing studies in light of Fisher's Fundamental Theorem of Natural Selection, extend the list of published reports of genetic correlation and covariation, and evaluate many of the problems confronting further progress in understanding the genetics of life history evolution. I conclude that the study of ecology and quantitative genetics of natural populations is a prerequisite to the understanding of how life history characters might evolve and may lend some insight into the process of speciation.
