Orgin of the Australian Tropical Rainforest



Way back long ago a super continent known as Pagaea split up into two different continents, one named Laurasia and the other Gondwana. The continent of Laurasia was later transformed into what we now call Europe, and North America, while Gondwana took over the southern states such as South America, Africa, Australia, New Guinea, Antarctica, as well as India (3). As time passed Godwana broke up int multiple pieces and Australia drifted in isolation towards Southeast Asaia, it eventually evolved it’s on nature and different kinds of flora and fauna bean to come into existence. Furthermore animal began to develop such as the kangaroo and koala. As time passed scientist discovered that the present flora and fauna in the woodlands of Australia had essentially evolved from an original rainforest stock (3). The tropical rainforest are believed to be the oldest in the world. According to scientific evidence the tropical rainforest of Australia had survived in “refugia" for millions of years, somehow escaping ice ages, sea level rises, and demolition by volcanic activity (3).
Anthropologist have also recorded a group of people living around the rainforest in ancient times. They were known as the aboriginal rainforest people. The aborginals not only had language differences but also had distinct physical differences (3). Although the abiorgianls  settled in the Australian rainforest first it was not them who explored the jungle but the European settlers. They discovered sugar cane  and timber. The excitement and curiosity of finding new timber lead the settlers to start cutting down trees through the rainforest and logging began to a popular practice for the settlers. in the 1960's and 1970's that biologists began to realize that the area was fairly significant, and the region began to draw groups of conservation minded people living on the land.
