Rosa leaned a 87 foot ladder against the side of a building. The base of the ladder is 11 ft of the base of the building. The top of the ladder is 11 feet from the top of the building. How tall is the nearest tenth of a foot, is the building?

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.
