Answer 2

Answer:

The arms and chest of a human do not have anywhere near enough muscle mass to provide the necessary power.

Explanation:

A bird can fly because its wingspan and the wing muscle strength are in balance with its body size. It has a lightweight skeleton with hollow bones, which puts a smaller load on its wings. In other words, humans are not too large to fly, but our strength simply cannot support our weight in flight.
