CEFR C1

reproductive isolation

noun phrase

Meaning

A state where a group of organisms is separated from others of the same species, preventing them from interbreeding and eventually leading to the formation of new species.

Examples

  • Reproductive isolation can occur due to geographical barriers, such as mountains or rivers, that prevent individuals from different groups from mating.
  • The process of reproductive isolation is a key driver of speciation, as it allows populations to evolve independently and adapt to their local environments.
