Answer:
skydiving behavior
Explanation:
The flight is an amazing adaptation that consists in the use of aerodynamic forces by flapping the wings. In vertebrates, flight evolved in three independent events: in pterosaurs (i.e., prehistoric winged reptiles), birds, and bats (mammals). In tetrapods, i.e., vertebrates with four legs, it is believed flight had a gliding origin, thereby this feature would have emerged as a consequence of the skydiving behavior necessary to steer the descent.
