Evolution From A molecular PerspectiveIntroduction Why globular evolution?     Evolution has been a heavily debated issue since Charles Darwin firstdocumented the theory in 1859. However, until clean recently, adaptation at amolecular level has been overlooked overlook by the scientific world. Now withthe help of modern technology, the protein sequences of estimablely every(prenominal)(prenominal) knownliving thing have either been established or be in the process of establishment,and are widely accessible via the internet. With the cognition of thesesequences, one rear end actually look at several organisms inherited codes and confidential informationout the similarities. Entire genomes of creatures have been sequenced, and thehuman genome project is vigorous underway and ahead of schedule. With this newknowledge comes worries, for humans, however. What if the information stored inour genes was accessible to the public? Would insurance companies and employersbase their selections on these traits? Also, with the total knowledge of everysequence of every amino acid chain in a souls genome, couldnt a laboratoryperceivably reconstruct an exact copy of, or clone, that person? These are allissues that will have to be dealt with in the near future, but for now we needonly concern ourselves with the objective reflectivity of these proteins in ourattempt to explain our ever mysterious origin. As humans, we are the firstcreatures to question exactly where we came from and how we got here. Somecling to religious creationism as a means, while others embrace the evolutionarytheory. As of now, and possibly forever, incomplete gage be proven to be absolutetruth with vexed facts, and both have their opposing arguments. The point ofthis paper being serene is not to attempt to abolish the creationist view, afeat that at this point seems impossible, but merely to educate those seeking tounravel the mystery of our extravert by pointing out facts that exist in themodern world and that can be quite easily and independently researched. It isconceivable that the two ideas, creationism and evolutionism, can existsymbiotica lly due to the fact that both views have very broad(a) points.Hemoglobin Comparisons between species     Of all the proteins in living things, hemoglobin is "the arcminute mostinteresting substance in the world," as American bioche... ...FHDHPETLDRFDKFKGLK--TEPDMKGSEDLKKHGQTVLTALGAQ--LKKKG 6.     ----TEWEHVNKVWAVVEPDIPAVG--LAILLRLFKEHKETKDLFPKFKEI---PVQQLGNNEDLRKHGVTVLRALGNI--LKQKG1. humankind Man 2.
