A tree is 8.5 feet tall and it casts a shadow that is 3.5 feet long, as shown below. How far is the distance, in feet, from the top of the tree to the far end of the shadow? Round the answer to the nearest hundredth.

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.
