Certain human diseases may have evolutionary epigenetic origins

Ninety-six percent of a chimpanzee's genome is the same as a human's. It's the other 4 percent, and the vast differences, that pique the interest of Georgia Tech's Soojin Yi. For instance, why do humans have a high risk of cancer, even though chimps rarely develop the disease? In research published in September's American Journal of Human Genetics, Yi looked at brain samples of each species. She found that differences in certain DNA modifications, called methylation, may contribute to phenotypic changes.

Changes in DNA methylation might be linked to evolution of humans' vulnerability to diseases

Chimpanzees rarely get cancer, or a variety of other diseases that commonly arise in humans, but their genomic DNA sequence is nearly identical to ours. So, what's their secret? Researchers reporting in the September issue of the American Journal of Human Genetics, a Cell Press journal, have found that differences in certain DNA modifications, called methylation, might play a role.
