model is more adequate than the mechanical
model for explaining DNA, the cell, other biological subject matter (as well as subatomic

The implication of the new subatomic
physics was that certainty was replaced by probability, or the notion of tendencies rather than absolutes: «we can never predict an atomic event
with certainty; we can only predict the likelihood of its happening»... This directly contradicts the mechanistic
model we explored above, and it implies that a subject such as normal birth needs to be looked at as a whole rather than its parts...»
