- Title
Extending microevolutionary theory to a macroevolutionary theory of complex adaptations.
- Abstract
Even those willing to accept, on principle, that gradual allelic substitution is a model for evolutionary change and that adaptation is due to natural selection, might still wonder whether that was enough to explain complex adaptations. Jamniczky and Hallgrimsson (2009) compare covariance structures of natural populations of rodents and laboratory-bred mice, showing that its structure is conservative in natural populations but highly variable across mutant strains of laboratory mice. The earliest (Lande 1976) begins with Simpson's concept of the adaptive landscape, and models a single trait under stabilizing selection and random genetic drift; the next, also by Lande, extends the multivariate quantitative-genetic theory to explain a well-known trend, brain: body allometry (Lande 1979).
