Speciation
Easybiology
Geographic isolation leading to divergence defines which speciation type?
Select the correct option:
Solution
Incorrect! Answer:
Allopatric
- Speciation: The formation of new and distinct species in the course of evolution.
- Allopatric Speciation: Occurs when a population is divided by a physical, geographic barrier (like a mountain range, river, or ocean).
- Divergence: Once separated, the two groups cannot interbreed. They accumulate different mutations and face different natural selection pressures until they become separate species.
- Sympatric Speciation: Occurs within the same geographic area due to other factors like polyploidy or behavioral changes.
