Subject: RE: BS: Logic and the laws of science
Mutations that are "not best adapted but which hang in there" are adapted. This is not black and white. Theories don't "demand" things. A theory is an attempt to explain. If the thing you are investigating doesn't fit the theory, then it's the theory that needs modifying. And generally speaking, a species that has succeeded for thousands or millions of years, then starts to "fail," will do so because the environment has changed, or it has come under new competition, or it is succumbing to disease, or it is being predated on with new vigour.
