Today’s feedback looks at the possibility of different mechanisms for evolution, and Dr Jonathan Sarfati shows why how what we know from chemistry and physics works against abiogenesis, and what we know about biology works against evolution. Mitchell R. from the United States writes:

Hey guys, I am pretty convinced now that evolution could not happen by natural selection and mutations but I was wondering if it could be possible that there is a different mechanism that is undiscovered yet? Or will evolution always be tied down to natural selection and mutations? Thanks, Mitch

Dr Jonathan Sarfati responds:

Dear Mr R.

Thanks for writing to CMI. Of course, anything is possible, at least in terms of logical possibility, if we want to go down that track. Maybe aliens seeded life on earth. But when it comes down to it, there are only the following possibilities:

The problem for the evolutionists is precisely what we do know about chemical laws.

  1. Natural law, whether we know it or don’t.
  2. Chance.
  3. Natural selection.
  4. Design.

Taking them in order:

  1. The problem for the evolutionists is precisely what we do know about chemical laws, so it is not an appeal to ignorance or “God of the Gaps“, as opposed to the far more common “Evolution of the gaps” that atheists resort to. We know the laws by which amino acids and nucleotides behave, and the laws go in the opposite direction (see for example Some thermodynamics criticisms and answers (#2)) for the purely chemical aspect as well as the fact that the building blocks do not combine to form information-rich peptides. (From a philosophical point of view, here is how I think Natural Law should be understood).
  2. Probabilities are just too low (see Answering another uninformed atheist: Galileo, Miller—Urey, probability). See also the rebuttal to a common evolutionary counter-argument Cheating with chance.
