Geographical isolation

defined as when the ancestral species are separated geographically and thus, over time, cannot interbreed anymore.

Hybrid zones

may be formed when allopatric populations come back into contact with one another
region in which members of different species meet and mate, and maybe produce offspring of mixed ancestry
has three possible consequences:
Reinforcement
cannot interbreed
most common
Fusion
can interbreed and produce offspring
can form new species
offspring cannot interbreed with parent species
Stability
can interbreed and produce offspring
can form new species
offspring can interbreed with either of the parent species
