Origin of Bird Flight Explained

Flight theories:

1. Flapped to assist running up ramps.

2. Feathers as spoilers to stick to tree as bird runs up.

3. Leapt to avoid predators (feathers assisted leap)

4. Gliding animal extended glide with feathers and flapping.

Thank goodness Edison invented a better light (Volta invented a means of generating electricity and made a glowing piece of copper). Because, before Edison, there was nothing to screw into all of those light bulb sockets and power plugs.

Iron don't float....so planes can't fly. But they are made of anodized aluminum. Aluminum don't float. Oh...they fly by making the air take a longer path over the wing (so pressure is lower on top). Then, how do they fly upsidedown?

Fish have to climb trees rapidly to get away from cats.

Insulation, with later modifications for flight or gliding.
