Definition

Etymology

Example

Sympatric speciation is thought to occur when populations within a species evolve reproductive isolation mechanisms, such as differences in mating behaviors or timing, while living in the same geographical area.

Usage Notes

Sympatric speciation is a complex process that is still not fully understood. It often involves strong selection pressures and can lead to the formation of new species with distinct ecological niches.
