Evolution and Australian Species

Evolution can be described as process of organisms developing from there earlier forms of life of life. Evolution firstly became an idea from a group of ancient Greek thinkers. But when trying to introduce these ideas to the residents of Europe, they believed this must be false, as they already believed in the interpretation of the bible. This idea of evolution only began to rise again when Jean-Baptiste Lamarck the French naturalist came up with a theory how organisms evolved, he believed that they evolved through their efforts to the response of the demand of their environment

“Australia is home to many interesting phenomena, amongst them its weird and wonderful wildlife. 86% of plants, 84% of mammals and …show more content…
He is mainly recognized for the two ideas that he proposed about evolution. His first idea was that
“as organisms adapted to their surroundings, nature also drove them inexorably upward from simple forms to increasingly complex ones”. – Lamarck.
This theory of use and disuse gave an reason too why species would lose functions that were not needed by the organism giving them new traits that would be more useful to what the organism is trying to accomplish in its habitat

Lamarck’s second theory was the cause of a lot of controversy. In his second theory that inheritance of acquired traits, he believed that changes in an organism could be due by an environmental event in the organism’s habitat. He also believed that these traits could be passed down to the next generation of organisms, which would of benefit the population and creating new kinds of species. Some of this is possibly not true and would require years of constant gene changes for the species to adapt to their environment and could not instantly be passed down from one specie to another. This was his idea of continuous progress; he believed that each day in some way we would be improving. His theory proposes that the positive evolutionary changes result from changing needs or changes to the …show more content…
Darwin believed that all species had descended from a common ancestor, which down the line of natural selection had created it own modification to the species up until the point we are at today. Darwin had a brought strong case for how evolution works.
Darwin has taught us a lot about evolution in him time and it is no longer appropriate to claim that evolutionary biologists believe that Darwin's theory of Natural Selection is the best theory of the mechanism of evolution. It as an easy to understand way of thinking about evolution but his theory has now been updated with the new more modern theory of evolution Neo-Darwinism and like demonstrates it add on to the original theories that Darwin first set for us. It has been widely promoted in the popular press and the image of "survival of the fittest" is too powerful and too
