A New Explanation for the Way Humans Evolved from Apes

It’sCharles Darwin‘s two-hundredth natal day , and we still do n’t know why humans and chimps share 99 percent of their DNA , yet are such unlike brute . A fresh report published today advances a unearthly new theory .

A group of investigator at the University of Washington have discovered that there is one surface area where human and ape DNA mutated very rapidly during the time that they were diverging on the evolutionary tree . Both mintage ’ genomes mutate a great deal in areas where there are a lot of repetition sequence of DNA . human , like most creature , have areas of their genome where the same chunk of inherited code is repeated once or several metre .

accord to the University of Washington , Pb researchers Tomas Marques - Bonet and Jeffrey M. Kidd said :

The new study shows big differences in the genomes of homo and great imitator within duplicated successiveness arrest speedily develop gene . Most of these differences occurred at a meter just prior to the speciation of chimpanzee , gorilla , and humans .

So is it possible that the reasons for such spectacular difference between man and chimp can be trace back to these quickly - mutate repeat region ?

chimpanzee and mass share almost 99 percent of the non - duplicated sequences of their genomes ; their proteins are virtually identical ; and there are very few rearrangement that distinguish imitator - human chromosome . In line , the investigator noted that the duplicated sequences show much more variation than the other portions of the hereditary codification .

But this is such a new country of research that we postulate to be conservative before describe any loyal conclusion . While this looks like a bright boulevard for further inquiry , the research worker explained :

There is still no last reply as to why chimps and humans are unlike . Maybe segmental duplications that are specific to humans are another layer to explore , or maybe the distinction between human being and Pan troglodytes is not launch in these familial difference . What is certain is that transmitted differences kick in significantly to what makes a human and chimp unlike , and we know that these regions of our genetic codification are changing much more speedily than most others . The next challenge will be lay down sense of all these conflict and the genes that are affected by them .

While former studies have suggested that we will learn more about ourselves by studying so - called junk DNA , or DNA that does n’t seem actively call for in coding for proteins . But this unexampled work suggests we study the parts of our genetic code that replicate themselves . These odd , repeated segments of our deoxyribonucleic acid may be the samara to understanding why we mutated into the hairless , psychoneurotic hominids we are , rather of turning into happy - go - prosperous bonobos .
