Stop twisting the argument. The hypothesis is that mutation/selection are adequate to cause speciation. Mutation exists and selection exists. These are verified premises. That mutation/selection causes speciation is purely hypothetical as we do not have any specific evidence of it happening even though there is nothing to suggest it is not possible. This hypothesis doesn't even demand that speciation IS caused by mutation/selection, only that it is a possible mechanism of many.
I've noticed in the last few responses to things I've written that you are having difficulty with reading comprehension. It would be a lot more fruitful if you actually addressed what I wrote rather than what you think I said.
It is because mutation and selection (in regards to speciation) are hypothetical that one must list them as individual degrees of freedom when working out an Occam's Razor problem for how speciation is achieved (i.e. via Evolution or Intelligent Design).
Post #194 does that. Please refer back to it.
