State which is greater (6-8)x10 or 6-(8x10)

(6-8)x10is the greatest

Step-by-step explanation:

(6-8)x10= -20

6-(8x10)= -74

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.
