Flight has independently evolved 4 times (insects, birds, pterosaurs, and mammals) in the history of life on earth. Flight is an example of convergent evolution.
The emergence of flight is arguably one of the most astounding examples of convergent evolution. Insects, bats, birds, and pterosaurs are the four groups that seem to have independently acquired flight throughout history. There was not just one flying progenitor from whom these four kinds of animals descended.
The cursorial theory, the alternative idea, contends that flight evolved in tiny, bipedal terrestrial theropod dinosaurs that raced along the ground while stretching their arms out in pursuit of prey or dodging predators. The creatures could fly because of the extra lift provided by the feathers on their forelimbs.

The Organization of American States was founded in the Conference held in Bogota, Colombia, in April 1948, whereby 21 countries (including the U.S.) were part of.

He used more pacifistic methods in order to help free India from the British raj, or harsh rule (loose translation). Some of these methods would be simple defiance by taking his own salt when there was a law saying that they can't collect their own, or by starving himself for extended periods of time.
