Most would think that Biology is all the gross stuff, seeing Frog innards and cuting them up. Well, although biology DOES involve itself in learning the inner system of a living thing. Biology, is the study of living organisms, divided into many specialized fields that cover their morphology, physiology, anatomy, behavior, origin, and distribution. So it's not really a surprise that in Modern Technology that Biology wants to understand how it could heal living things by studying wha'ts inside it. Safely without cutting things up all the time, of course. It's healing not killing.
