Hybrid Zones
Captions available
The idea
A hybrid zone is a geographic area where two closely related, recently diverged species continue to interact and interbreed, producing hybrids.
In practice
A narrow band where two related species' ranges overlap and hybrids regularly appear is a hybrid zone under observation.
Where people slip
A hybrid zone's existence alone does not mean speciation failed — its long-term outcome depends on hybrid fitness.
