Life In The Universe :: essays research papers

In the selection I take aim chosen Chapter 6 of Life in the Universe The phylogeny of Life on Earth begins with the theories of Darwin and natural selection and how survival of the fittest was 1 of the main theories of evolution of life of an organism. Although it is a good speculation, and has been tested by means of years it is not one of the main priorities of evolution. There was a debate of an outside force that forced the funas to extinction, not because it was unable to adapt to an environment. withal the past of origin goes too far back and is so mingled that there is no sure way to point a legitimate time or place in the history of our origin, unlike the naturalise of nature. For example Homo sapiens come to be through aflutter complexity. Human arose from thousands of events happening in time that altered our past in a dramatic way. In order to understand the drastic changes we boast to understand not just the principals of evolution but to understand the theor y and life styles of fossils found. Complex creatures dont mean that it has a cleanse hazard of survival and evolving into something bring out. Yet the simplest form of creation like bacterium still rule all with the enormous amount occupying the earth. heretofore the much 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 hold up in the future. Bacteria occupy a wider range of space on earth and are an indestructible geek of organism. Humans and other type of complex organisms have to worry about their extinction while bacteria on the other hand have a low chance of getting wiped out. Even as they are simple organisms they also have the same chance as we do to evolve without the tough struggle. study the two it shows that complexity was not good or favored bribe in evolution. Complexity is probably a bias made by us for the reason of our being and o ur evolution. Evolving in such(prenominal) a way, it would land that animals evolve by greater complexity, or ecological adaptation 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 tenacious for evolution of these type of species (including us).
