I learned about Mendel and heredity in grammar school, in fact, my assertions are based on these very laws of inheritance, as well as the common sense laws of breeding that evolutionists like to ignore. The fact remains that, if genetic mutations are the cause of genetic changes that alter the genome to the point where it could be called a truly new species (and not just a new breed), that genome would be incompatible for breeding purposes with the parent organism. For sexually reproducing animals, this requires the exact same random mutations to accumulate in reproductive cells that would lead to the production of both a male and female of the “new” species. Otherwise, the first specimen of the “new” species would find themselves both unable to breed with their parent species, and unable to find a breeding partner of their “new” species, since none would exist.
Are you implying that cross species reproduction is always impossible?
Perhaps grammar school was too early, because your previous statements evidences lack of understanding of these principles:
"The only possible way the evolutionists can overcome this obstacle, that I can fathom, is if by some miraculous confluence, all of the exact same genetic mutations were passed down to at least one male and one female offspring"
A single mutation (in either male or female) may be passed to the offspring, and then become widespread in the population, if it promotes survival and further breeding.
