speciation

Question

Geographic isolation leading to divergence defines which speciation type?

RankGuru · Accepted Answer

1. **Speciation**: The formation of new and distinct species in the course of evolution.
2. **Allopatric Speciation**: Occurs when a population is divided by a **physical, geographic barrier** (like a mountain range, river, or ocean).
3. **Divergence**: Once separated, the two groups cannot interbreed. They accumulate different mutations and face different natural selection pressures until they become separate species.
4. **Sympatric Speciation**: Occurs within the same geographic area due to other factors like polyploidy or behavioral changes.
