An airplane flies for 6 hours against the wind on the way to your destination and 5 hours with the same tailwind on the return trip. The speed of the plane in still air is 550 miles per hour. Find the speed of the wind.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
