Extinction & Speciation
- Extinction happens if you can't
evolve quickly enough
- Many species that don't
exist any more
- Can be said to be extinct
- 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
- Isolation and natural selection
lead to speciation
- Speciation is the development of a
new species
- Isolation is where populations of a
species are separated
