The “zombie” gene may explain why the long-lived pachyderms rarely develop cancer and how large animals evolved.
A Cancer Mystery
Elephants are a paradox for scientists. The giants appear largely resistant to cancer, which is odd as their long lifespans and humongous size ought to make them highly suscep
