ExtinctionSpec 4.6.3.6

Extinction occurs when there are no remaining individuals of a species still alive.

You need to be able to describe factors that may contribute to the extinction of a species. A species may become extinct because of:

  • a change to the environment over geological time
  • new predators
  • new diseases
  • new, more successful competitors
  • a single catastrophic event, such as a massive volcanic eruption or an asteroid collision.
