Australia
over the world.
Most of its workers do not work in factories or on farms. Two-thirds of them work in shops,
offices, banks or schools.
Animals, birds and plants.
A strange thing happened when ocean blocked off this island continent. Appearently none of
the mammals that survived in Australia were of the sort that later changed into the familliar
mammals of the rest of the world. The ancestors of cats and tigers, of wolves and dogs, of
elephants and sheep just were not there. As a result,the reptilelike mammals that have died out
everywhere else in the world are alive in Australia. The higher groups of mammals that
developed in the rest of the world after Australia was cut off had to be brought there millions
of years later by the colonists.
Australia is,in fact, a continent-sized museum of ancient animals, modernised along certain
lines by their own separate evolution. Two of the strangest animals in the world are the spiny
anteater and the platypus. They are reptilelike mammals
