1. Evidence of Evolution:
Biogeography
Harriet was a tortoise that Darwin took with him
when he left the Galapagos Islands in 1835. She
spent most of her life in an Australian zoo until
she died in 2006 at the age of 175 years old.
5. Biogeography
The behaviour of different species depends on their
environment also. For example, those with no
natural predators will not avoid humans.
10. Biogeography
4) These uniquely evolved species are related
to a species on the nearest continent.
These treecreepers are
actually 2 different
species. Can you see the
differences?
