Ever wonder how evolution comes to be? How some species win and others lose? Evolution has many different ways of making organisms all better‚ faster‚ and more adept to live. Four big categories of the mechanisms of evolution are natural selection‚ gene flow‚ genetic drift‚ and mutations. The majority of the time‚ nature goes by a trial and error system that can take up many centuries to come up with a change that is beneficial. Natural selection is the process in which nature removes its mistakes

In 1788 the first fleet disembarked on the shores of Botany Bay. Shortly thereafter Australia became the first colony founded entirely upon the work of convicted felons.

While it began with the last common ancestor of all life‚ the topic usually covers only the evolutionary history of primates‚ in particular the genus Homo‚ and the emergence of Homo sapiens as a distinct species of hominids (or "great apes"). The study of human evolution involves many scientific disciplines‚ including physical anthropology‚ primatology‚ archaeology‚ linguistics‚ evolutionary psychology‚ embryology

The Evolution of Television Introduction Television is one of the most valuable contributions of the scientists in the last century. The world ’s first real television picture was produced by a Scottish inventor called John Logie Baird in 19251. It was nearly a hundred years to the first television appears‚ television has evolved a lot in appearances and functions. Darwin’s theory suggests that the variation among living organisms and the evolution of a species is caused by the theory of natural
