The Scientist Quotes Prof. Wade Hazel
February 4, 2006
February 4, 2006, Greencastle, Ind. - "It's a pretty convincing demonstration and it's a really nice model," Wade N. Hazel, professor of biology, tells The Scientist. Dr. Hazel is quoted in an article examining the finding that "polyphenisms -- distinct phenotypes emerging from identical genomes -- can evolve through genetic stabilization of a stress-induced phenotype. The authors (of the research) suggest that complex traits, such as color change, may evolve suddenly when a mutation in a developmental hormone reveals previously hidden genetic diversity."
The story includes several quotes from Professor Hazel, who was not involved in the study, as well as links to some of his work. Melissa Lee Phillips writes that the DePauw professor believes that the researchers' "results fit well with previous theoretical work. Still, Hazel noted that he would have liked to see 'whether these hormonal changes that they document in their selected lines actually occur in the species that exhibits the polyphenism in the wild.'"
