You're probably right, although, some animals (some reptiles, I think), have largely maintained their form over a 100 million years or more. I have read that the sperm count among men is falling, and so, we may be forced to resort to cloning someday, or, have a human race that is perhaps all women if the Y chromosome should disappear???
