Answer the question please.
You're expecting someone who can't deal honestly with reality in math to deal with honestly reality in science?

For instance he asks:

How many gliding birds can you name that have broad, short wings; as opposed to longer, narrower wings? (I won't even mention aircraft, lest some poor reader be caught sipping a beverage.)
When the question he should have asked is how many gliding animals have broad short wings as opposed to longer narrower wings.

Here are two:

Curiously they also have their wings between their front legs and their back legs.

Birds of course have evolved for flight, not gliding, and they evolved wings from single arms, not from skin between front and back legs (there is one that has feathers on both front and back legs), so using birds is a false analogy to bats, just as substituting an interest rate formula for a decay formula misrepresents decay.

Enjoy.
