You use in line to best fit the set of data to make a prediction about the unknown value. the correlation coefficient for your data set is -0.015. how confident can you be that your predicted value will be reasonably close to the actual value?

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.
