Hi Coragyphs,
To quote JAR "Okay, maybe we are finally getting somewhere."
The list you gave me were all mammals, were they not? Thank you. You seem to have stayed with my proposal of focusing only on the nursing aspect of mammals for which I thank you.
I assume that you agree that evolutionary changes happen near the point of conception; that the physical charasterics of a birthed animal do not change. In other words and using a simple example, a male amphibian, bird, reptile, or some other "kind" of non-mammal fertilized one or more eggs of a female of the same kind and normally an animal of the same kind would have been the offspring. When the material within the egg that determines what the offspring will "look" like is disturbed then an unexpected (different) offspring results.
Now, focus on that very moment when the "non-mammal ancestor" is expecting to feed it's offspring with insects or expecting them to take care of themselves. In the "nest" is one helpless mammal offspring which must nurse to survive. The "non-mammal ancestor" has no way to feed the mammal offspring and the mammal offspring can not take care of itself. What do you predict the result will be?
Just out of interest, what non-mammal is the proposed "evolutionary non-mammal ancestor" of all the mammals you listed?
Very best regards,
BAE
