Australia is believed to be the oldest continent. The fossils found there are remains of the earliest life on earth, dating back millions of years. Evolutionists know Australia to be a continent with some of the most unique collections of life.
Because of the age of the fossils and stromatolites found in Australia, the continent is considered one of the best to find unique artifacts involving both geology and evolution.
Australia is a good example of the evolutionary principle of isolation, because animals that live on that continent are some of the most unique animals found on Earth. This includes animals such as the platypus, kangaroo and the spiny anteater, known as the echidna.
