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.

so what this question is saying is just that what do School used to do when they had civil conversations because different schools you should contribute no white no black no white and black together but now American schools are saying that white and black can come together that's so amazing because a lot of kids have black friends a lot of kids have white friends without people coming together for the largest amount like I would say about 100 million people orchids or 10000 million people I contribute this order to the law because now no one knows if Donald Trump will be the president or Hillary Clinton will be the president of mostly people don't want Donald Trump but whoever you get you deserve because if not we will have no president America be just a dump in our life that's why you need to take courage out of someone that is willing to do something for this but my final answer is that I would say 20 hundred million thousand kids contribute this order thank you everyone
Primary source is the firsthand experience and evidence of an event, where the any given information first appeared (initial report). The secondary source uses the first source in order to give its information (for example: document that analyzes primary source documents).
When analyzing historical event a researcher use a secondary source instead of a primary source because he uses the primary source as the imput information (facts, events, dates, names) in order to analyze them, connect them and explain them in his work.
