Errors of distribution

The appar­ent near iden­ti­ty of the genome of chim­panzees and man—98.5% of the DNA sequences are the same—is puz­zling. But the dis­tri­b­u­tion of differences—and their expres­sion in proteins—is what makes dis­tant sim­i­lar­i­ty of appar­ent near iden­ti­ty. The dif­fer­ences (1.44%) are dis­trib­uted in a way that eas­i­ly explains the dif­fer­ences in the out­come, as Japan­ese research con­firms bq. “These dif­fer­ences are suf­fi­cient to gen­er­ate changes in most of the pro­teins: indeed, 83 per­cent of the 231 cod­ing sequences, includ­ing func­tion­al­ly impor­tant genes, show dif­fer­ences at the amino-acid sequence lev­el,” they added. (“Reuters”:http://www.reuters.com/newsArticle.jhtml;jsessionid=R40UOPO2ORK5GCRBAEOCFEY?type=scienceNews&storyID=5264726&pageNumber=1) The error of dis­tri­b­u­tion is a pret­ty pow­er­ful error. Imag­ine two pieces of music that—considered one bar at at time—share nine­ty-eight per­cent of the same notes. Think how dif­fer­ent the two pieces could be. Mozart and Shostakovich.
