Charles G. Sibley advanced a very controversial methodology to compare the DNA of differing species. Sibley initially attempted to determine the extent of genetic differences between bird species--but his work was ultimately expanded to characterize...

Charles Sibley, a Yale University professor of biology, and his colleague Jon Ahlquist developed a process for comparing deoxyribonucleic acid (DNA) between species. Not only did the procedure reveal the genetic similarity of two species, but it acted...

1917-1998 American molecular biologist who during the 1980s adopted a controversial technique for comparing the DNA of different species to document ranges of genetic differences. Sibley applied this technique to the problem of human-chimp-gorilla...

Charles Gald Sibley (August 7, 1917 – April 12, 1998) was an American ornithologist and molecular biologist. He had an immense influence on the scientific classification of birds, and the work that Sibley initiated has substantially altered our...
