Sharks with fingers?

It’s scary to imagine sharks having more than just teeth to grab ya with … what would it be like if they had fingers? University of Florida scientists discovered that sharks actually have the genes in their DNA for making fingers, but the developmental time devoted to those genes is too short to actually allow the fingers to appear (Hopefully, I understood that correctly). This discovery apparently surprised the researchers as they didn’t think the “finger genes” would be present at all in sharks. Having learned about the role of small developmental time in not allowing fingers to grow, the understanding could help scientists treat human birth defects involving such digits. Read here for more.
