This reminds me of a question I've thought of on occasion. There are no
known instances of speciation occurring in selective breeding. But,
suppose speciation did occur. How would we recognize it? Breeders
normally work with small enough populations that it would be very unlikely
that a sufficient number of individuals of the new species would exist
that the breeder would have any chance of reproducing them. They would
simply seem sterile to him, and he would write it off as a failure. So,
how do we know speciation has never occurred in selective breeding?
