Questions and Answers

What is allopatric speciation?

A type of speciation that occurs when members of a population are separated by a geographic barrier and become two separate species.

What is sympatric speciation?

Speciation in which new species evolve from a single ancestral species while inhabiting the same geographic region.

What is parapatric speciation?

Speciation that occurs when a species is spread out over a large, continuous geographic area, but individuals tend to mate successfully only with members from their own region.

What is peripatric speciation?

When small groups of individuals break off from the larger group, become geographically isolated, and form a new species. Signup and view all the answers

Study Notes

Types of Speciation

Allopatric Speciation
- Occurs when populations are geographically separated by barriers.
- Leads to the formation of two distinct species over time.
Sympatric Speciation
- New species evolve from a single ancestor while occupying the same area.
- Often involves behavioral or ecological factors rather than geographic isolation.
Parapatric Speciation
- Involves species that are distributed across a continuous geographic region.
- Mating occurs primarily between individuals in close proximity; environmental differences cause speciation.
Peripatric Speciation
- Happens when small groups from a larger population become isolated.
- Geographical isolation can lead to genetic drift and the emergence of new species.
