Life in the Universe

A detailed Summary of Life in the Universe

In the selection I have chosen Chapter 6 of Life in the Universe; The Evolution of Life on Earth begins with the theories of Darwin and natural selection and how survival 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 tested through 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 adapt to an environment. Also the past 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, unlike 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 understand the drastic changes we have to understand not just the principals of evolution but to understand the theory and life styles o!

Complex creatures don't mean that it has a better chance of survival and evolving into something better. Yet the simplest form of creation like bacteria still rule all with the enormous amount occupying the earth. Still the more comp

way, it would state 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 long for evolution of these type of species (including us).

he view of evolutionary path will open more doors to the awareness of other species and the knowledge we gain from them.

It is thought that mammals survive that castrophobic moment in time is due to the very small size they were, where as the dinosaurs in great size died out. They have a greater chance of not getting extinct by the small size and able to hide in many more places and it was easier for them to branch out to the territory of the dinosaurs since they were extinct.

In chapter 6 Evolution of Life on Earth, I totally agree with the process of evolution and how we tend to take proportion of the situation and see ourselves as a greater being or species upon all others. When other species evolved before us and is still going on with their lifestyle for example bacteria. Bacteria are among us everywhere yet they are the least complex and very little. We in the other hand are greater in size and very complex with vertebras also with a brain but still worry about our future in a time of extinction. We see ourselves above it all and tend to base history on and around us, but really we are just a little twig in a big brush that continues to grow and expand without notification. In order for us to understand evolution is for us to take in and understand our place in the evolutionary period and other evolving species as well. So the coexistence with one
