Meal consists of an appetizer, a main dish, a side dish, and a drink. there are 3 appetizer choices, 6 main dish choices, 5 side dish choices, and 4 drink choices. describe two ways you could find the number of possible combinations. choose one of the methods to find the answer, and explain your choice.

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.
