I've been looking for some example of gain-of-function mutation that has derived from speciation.
That seems backwards to me. Mutations, including gain-of-function mutations in specific, are the stuff of which speciation is made, not so? Wouldn't it be more reasonable to ask for examples of speciation derived from gain-of-function mutation, rather than the other way around?
Most speciation is not driven by natural selection, but by accumulation of genetic differences. Lenski's E coli experiment showed a gain of function - ability to use citrate as a nutrient.
