I do not "quote" people and I do not refer posters to other posters. That is what makes these threads go absolutely crazy.
You never see me put up more than a sentence or two, unless it is tech.
But, perhaps this is tech.
The reason some species can't do what chelle asked is that they have not yet "mutated". Perhaps a mule will "mutate" this week and then that mule will be able to do it and produce offspring where he could not last week.
Again, simple stuff and the end of my conversation. Why make it hard?

Anyone who has ever studied Anatomy & Physiology, Biochemistry, Microbiology, etc, etc will tell you that life is anything BUT simple. Even single-celled organisms are amazingly complex and even the slightest variation from very narrow functional parameters for ANY living organism can mean death, or mutation.......it is this very complexity of life to begin with that has lead to such an amazing diversity of our biosphere.
