Demographic and genetic constraints on evolution.
The American naturalist - 1 Dec 2009
Gomulkiewicz Richard, Houle David
Abstract excerpt
Populations unable to evolve to selectively favored states are constrained. Genetic constraints occur when additive genetic variance in selectively favored directions is absent (absolute constraints) or present but small (quantitative constraints). Quantitative--unlike absolute--constraints are presumed surmountable given time. This ignores that a population might become extinct before reaching the favored state,...
