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 of fossils found. 
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 complex we are doesn't 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 space on earth and are an indestructible type 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. Comparing
the two it shows that complexity was not good or favored issue in evolution. Complexity
is probably a bias made by us for the reason of our being and our evolution. Evolving in
such a 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). 
With the evolution of species some must get erased to make way for new animals to emerge,
for instance environmental changes. Dinosaurs for an example was thought to rule over the
earth before mammals but the truth stands out that mammals and dinosaurs coexisted
together for about 100 million years, just that mammals were small creatures. History
books tend to be bias about the way that we evolve to this state. Even in books they
state humans as the last of the evolutionary chain when other animals are evolving ahead
or with us. They don't talk about the past of the chain and only little bits and pieces
but the bias point of what has only evolved at that moment. Many species with
multicellular structure evolve to great numbers but those experiments died out the few
remaining branches branched out to more different types but they all have basic
anatomies. Mass extinction is another reason of evolution is through sudden changes
impacts that happen quickly that wipes out a lot of species but the best equipped tend to
survive and evolve more differently to suit the environment, like Darwinian. 
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. 
With the theories of evolution humans do not want to see themselves as an insignificant
branch of the tree of evolution. So the theories of us dominating all and how we are
greater rings in our mind that we stand above all species. So we will always be bias
about humans being greater in a tree of evolution then just a tiny twig broken and would
not grow out if not taken care properly. We will not understand the way of evolution
completely, if we do not accept the fact that where we stand is just as little as every
other species.
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 another does not interfere with each other's lives. Getting rid of
the bias we have for the view of evolutionary path will open more doors to the awareness
of other species and the knowledge we gain from them. 
Chapter 6 of Evolution of life on Earth and its relevance to the class by how organism or
species are evolving on our earth. Understanding our evolutionary past will give us hope
that somewhere in the universe there is such a process of evolution beginning or going on
in another planet. Giving us understanding of how life goes on and the possibility of
life starting shows us that maybe our future may not be so dim. Also gives us a chance of
better survival. This issue has to do with the universal life in the cosmos by us. The
planet Earth is too, apart of the cosmos and therefore is a big deal because it sustains
life in its presence. Our understanding the past leads us to the knowledge and hope
towards the future. Also we might be able to make a water-sustaining planet to have such
life evolve for our suitability.
