Evolution From A Molecular Perspective
Introduction: Why globular evolution?
Evolution has been a heavily debated issue since Charles Darwin first
documented the theory in 1859. However, until just recently, adaptation at a
molecular level has been overlooked except by the scientific world. Now with
the help of modern technology, the protein sequences of nearly every known
living thing have either been established or are in the process of establishment,
and are widely accessible via the internet. With the knowledge of these
sequences, one can actually look at several organisms genetic codes and point
out the similarities. Entire genomes of creatures have been sequenced, and the
human genome project is well underway and ...

we need
only concern ourselves with the objective observation of these proteins in our
attempt to explain our ever mysterious origin. As humans, we are the first
creatures to question exactly where we came from and how we got here. Some
cling to religious creationism as a means, while others embrace the evolutionary
theory. As of now, and possibly forever, neither can be proven to be absolute
truth with hard facts, and both have their opposing arguments. The point of
this paper being composed is not to attempt to abolish the creationist view, a
feat that at this point seems impossible, but merely to educate those seeking to
unravel the mystery of our forthcoming by pointing out facts that exist in the
modern world and that can be quite easily and independently researched. It is
conceivable that the two ideas, creationism and evolutionism, can exist
symbiotica lly due to the fact that both views have very good points.

hemoglobin chains of 7 different animals: a human man, rhesus monkey, cow,
platypus, chicken, carp (bony fish), and shark (cartilaginous fish) (See Table
1.1.) As is shown, the variations increase the further apart the organisms are
on the proposed evolutionary scale. A human man differs from a rhesus monkey
only twice in the first twenty-five amino acids of their alpha hemoglobin chains,
whereas a man and a cow differ in three areas. This is the product of many
thousands of years of natural fine tuning, if you will, through the slow but
precise processes of natural selection and adaptation. The fact of natural
selection shows us that while most genetic mutations usually prove fatal, ...
