A fellow by the name of Matthew Harris at the University of Wisconsin in Madison actually figured out a way to stimulate the gene for teeth, and so was able to actually turn the tooth gene on and produce teeth in chickens.
Kolega imenom Mattew Harris s Fakulteta Winsconsin u Madisonu je zapravo shvatio način na koji se može potaknuti gen za zube pa je u principu bio u mogućnosti „upaliti“ gen za zube i stvoriti zube kod kokoši.
