Cayman says that 94 dividend by 3 is 30 with a remainder of 4. he reasons this is correct because (3x30)+ 4=94.ehat mistake has cayman made? explain how he can correct his work

expression #3 is not equivalent. the others are.

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.
