As we made advances in science we were able to distinguish between a normal and abnormal living things. Take humans for example,
we can see his/her physical properties(height,weight,eye sight,hearing etc etc) and say he/she is a
normal person. But still some babies are born with abnormalities.
How often this occurs? Does it come under six sigma?Do it apply equally to all living things? or is it species specific?
