Why Is Jon E. Ahlquist Influential?

(Suggest an Edit or Addition)

According to Wikipedia, Jon Edward Ahlquist was an American molecular biologist and ornithologist who has specialized in molecular phylogenetics. He has collaborated extensively with Charles Sibley, primarily at Yale University. By 1987, both Ahlquist and Sibley had left Yale. In 1988, Ahlquist and Sibley were awarded the Daniel Giraud Elliot Medal by the National Academy of Sciences. In January 1991 , Charles Sibley and Ahlquist published Phylogeny and Classification of Birds, which presented a new phylogeny for birds based on DNA-DNA hybridisation techniques, known as the Sibley-Ahlquist taxonomy. At that time, he was an associate professor of zoology at Ohio University. In 1999, Ahlquist was retired.
