Evolution Of Life History Variation Among Female Mammals, Eric Charnov Feb 1991

Evolution Of Life History Variation Among Female Mammals, Eric Charnov

Biology Faculty & Staff Publications

A unified approach is developed for the evolutionary structure of mammalian life histories; it blends together three basic components (individual growth or production rate as a function of body size, natural selection on age of maturity, and stable demography) to predict both the powers and the intercepts of the scaling allometry of life history variables to adult size. The theory also predicts the signs (+, -) of the correlations between life history variables when body size is held constant. Finally, the approach allows us to eliminate body size to predict the dimensionless relationships between the life history variables themselves.
