Evolution From A Molecular Perspective

Evolution From A Molecular Perspective

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 ahead of schedule. With this new
knowledge comes worries, for humans, however. What if the information stored in
our genes was available to the public? Would insurance companies and employers
base their selections on these traits? Also, with the total knowledge of every
sequence of every amino acid chain in a person's genome, couldn't a laboratory
perceivably reconstruct an exact copy of, or clone, that person? These are all
issues that will have to be dealt with in the near future, but for now 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: Comparisons between species

    Of all the proteins in living things, hemoglobin is "the second most
interesting substance in the world," as American biochemist L. J. Henderson once
stated (Hemoglobin, 4). However bold this statement seems, it must be realized
that he
