The highest temperature ever recorded in a particular city was 105°F, and the lowest was - 27°F. Use absolute values to find the difference between the highest and the lowest temperatures.
The difference between the highest and the lowest temperatures is 2°F.

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.
