The sequencing of the medaka genome (Nature, 447:714-719, 2007, June 7) reveals an extremely high SNP rate of 3.42%, which is 3 fold higher than the distance between chimps and humans and 8 fold higher than the SNP rate among inbreed mouse strains and 34 fold higher than the SNP rate of humans. The SNP rate of medaka fish is the highest seen in any vertebrate species. This is of course what is predicted by the MGDH: fish is the least complex vertebrate and should have the highest DNA diversity among vertebrates. The two interbreeding populations of medaka seperated only 4 million years ago and yet have reached a genetic distance that is 3 fold higher than that of two distinct primate species, humans and chimp, that seperated 5-7 million years ago. Clearly, gradual accumulation of genetic distance has little to do with macro-speciation. <BR/><BR/>As new papers come out in the future, I will continue to write comments to update the evidence for the MGDH.gnomonhttps://www.blogger.com/profile/03362808932731126552noreply@blogger.com
