I am a supporter of evolution theory, but the "对达尔文进化论的疑问" made some sense to me.
Modern genetics support evolution theory under an assumption that mutations are random and the randomness of cons and pros are equally distributed. What if mutation is not perfectly random or equally distributed?
In the view of physics, every change needs to follow the first principle: the least potential energy principle. It means a change (or mutation) shall have direction or preference. I am in doubt that genetic mutations are purely random without direction because it is against the first principle.
Are there serious empirical findings to prove the genes mutate without direction?
