Original description:
Geographic illustration of SPATIAL ASPECTS OF SPECIATION:

1. allopatric speciation - physical barrier divides population
2. peripatric speciation - small founding population enters isolated niche
3. parapatric speciation - new niche found adjacent to original one
4. sympatric speciation - speciation occurs without physical separation
