All circumstantial evidence, Dr. A, thickly stuffed with assumptions. No hard evidence.
Faith, why don't you tell us what would you take as acceptable evidence. Then we could tell whether your expectations are reasonable or not, and perhaps this thread will be a little more interesting then the last two where you just kept shutting down all evidence given to you as not being acceptable evidence.
But remember that requiring a complete allele count of an organism before and after some speciation event will be considered unreasonable expectation by most people
