Week 1 Evolution

I am a firm believer of evolution.  To me it seems like the most natural thing in the world; we see it everyday with breeders, medicine, etc.  Evolution is a matter of change, whether in a positive direction or in a negative direction, in all living and non-living things.  Living creatures have been changing in order to adapt to their environment throughout the course of time, whether it is naturally or manipulated.  Naturally, we can use the example of the finches in the Galapagos Islands.  When climate changes occur, some species are more favorable than other; therefore, the favorable finches beat the unfavorable ones, hence changes within the finch species.  Manipulated evolution can be seen with breeders.  Many horse trainers study closely the different characteristics of horses and choose which ones are more favorable depending on the horse's purpose.  These are all positive changes of evolution.  But evolution can also be seen in a negative manner; where a species dies out, such as mammoths.  It may have been beneficial for other species, but it was definitely beneficial for the mammoths who ceased to exist.  In short, evolution is key in our world and is essential change, whether positive or negative, manipulated or natural.
