Extinction & Speciation

Extinction & Speciation

1. Extinction happens if you can't evolve quickly enough

2. Many species that don't exist any more

   • Can be said to be extinct

3. Reason why species become extinct

   • 1) Environment change
   • 2) New Predator
   • 3) New Disease
   • 4) They can't compete with another (new) species for food
   • 5) Catastrophic event (i.e Volcano eruption)
   • 6) New species development

4. Isolation and natural selection lead to speciation

   • Speciation is the development of a new species

5. Isolation is where populations of a species are separated
