Life In The Universe :: essays research papers

In the filling I have chosen Chapter 6 of Life in the foundation The Evolution of Life on Earth begins with the theories of Darwin and natural selection and how endurance of the fittest was one of the main theories of evolution of life of an organism. Although it is a good theory, and has been well-tried by dint of years it is not one of the main priorities of evolution. There was a reason of an outside force that forced the funas to extinction, not because it was unable to line up to an environment. Also the departed of origin goes too far back and is so complicated that there is no sure way to point a certain time or place in the history of our origin, impertinent the work of nature. For example Homo sapiens come to be through neural complexity. Human arose from thousands of events happening in time that altered our past in a dramatic way. In order to infer the drastic changes we have to understand not just the principals of evolution but to understand the theory and lif e styles of fossils found. Complex creatures dont mean that it has a better chance of survival and evolving into something better. Yet the simplest form of creation resembling bacteria still rule all with the enormous amount occupying the earth. understood the more complex we are doesnt mean we have a better chance of survival. More complex animals like dinosaurs have already been extinct, so that tells us a great deal about evolving or surviving in the future. Bacteria occupy a wider range of put on earth and are an indestructible type of organism. Humans and opposite type of complex organisms have to worry about their extinction season bacteria on the other hand have a number one chance of getting wiped out. Even as they are simple organisms they besides have the same chance as we do to evolve without the gnarly struggle. Comparing the two it shows that complexity was not good or lucky issue in evolution. Complexity is probably a bias make by us for the reason of our bei ng and our evolution. Evolving in such a way, it would state that animals evolve by greater complexity, or ecological allowance with the theories of Darwin. Still there is no proof to us that this was true. Also if complexity was such a great thing why did it take so long for evolution of these type of species (including us).
