our pectoral muscles would have to be huge, im not sure what other muscles would assist in the movement. our whole frame and structure would have to change to compensate for flight.

Ever see any fast swiming under sea creature, with fur?
Interesting and sort of obvious, but I was ignorant of this fact. Reminds me of the two major division of fish: True bones vs cartlige like sharks, rays, etc.Recent evidence shows that the small bats of the suborder microchiroptera are "true bats" or the original bats, who use echolocation and eat insects and other small animals. The larger bats of the suborder megachiroptera split off from older bats ages ago, but developed into such a away that they do not use echolocation, and are mostly herbivorous. ...
The largest bird that is capable of flight is the Andean condor. It weighs only 26 pounds (12kg) and has to have an 11-foot (3.5m) wingspan to get lift.If a human had wings, how big would they have to be? Im talking wings used for flight, like a bird.
Bird's weight goes roughly as the cube of size and the lift as the square (wing area). So if you double the characterist dimention of the bird (say body length), the weight goes up by factor of 8 but the wing area on by factor of 4. - that can not fly. So the wing to body ratio must at least double when you double the characteristic dimention of the bird.... I observe that the size of a bird's wings is not merely proportional to its weight. Large birds have wings that are much bigger, relative to their body size, than small birds. ...
