Just a quick question, hows does an individual body 'know' how to mutate to something beneficial , if it's never had it before ??. Because it seems to me you've confused 'random mutations that happen to be beneficial' with 'pre-determined development'. DNA expression is hard-coded to be immutable. That's why any genetic change is termed 'mutation', genetics are already 'hard coded and expressed' at conception, it's impossible for dna to change or 'develop' after gestation (except to mutate as sickness, disease). To clarify, the process of evolution is taught as a 'randomised compounding series of beneficial mutations over time', not anywhere, anything remotely considered to be shown as pre-determination, even though the 'change/ mutation' may be beneficial/ advantageous. Afaik, there has never been any cellular/ genetic proof or evidence for an encoded process of 'evolutionary development' of pre-determination ... If you have some, could you show me ...
