Character Displacement
Captions available
The idea
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.
In practice
Two finch species show more different beak sizes where both occur together than where either occurs alone.
Where people slip
Character displacement is evolved morphological divergence, not the behavioral partitioning, per Bio 3607, it builds on.
