Which numbers can best be used to estimate 22,957 + 54,998? choose exactly two answers that are correct.   a. 22,000   b. 23,000   c. 54,000   d. 55,000

answer: what equations are there

step-by-step explanation:

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.
