Which decimal number best describes the fraction 77 over 6?

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

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.
