State
Character displacement is evolutionary divergence of a trait, such as beak size, in two competing species where ranges overlap, reducing niche overlap beyond behavioral resource partitioning, per Bio 3607.
Show
Two finch species show more different beak sizes where both occur together than where either occurs alone.
Watch for
Character displacement is evolved morphological divergence, not the behavioral partitioning, per Bio 3607, it builds on.
