	Wrong!! The aerodynamics of Bumblebee flight have been known
for 10 to 15 years! There was even an article in Scientific American a
year or two ago explaining it! It seems that this "fact" that was
published decades ago has become so widespread that everyone believes
it because everyone says it!

	*odontoblastic* tubules!! Why didn't you say so in the first
place! There is a *world* of difference between *microtubules* and
odontoblastic tubules. The terms are *not* interchangeable.

	And if you would be more careful with your terminology there
would be less confusion and misunderstanding. The mechanism above at
least sounds plausible. I would like to see more studies to confirm
Dr. Steinmann's work before I decide whether I believe it or not.
(That is what *replicability* is all about).
