The length of time it takes Explore students to learn all the other students’ names can be approximated by a Normal distribution with mean 3.5 months and standard deviation of 0.3 months. After how long would you be 95% certain that a randomly selected student will have learned all the names?

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.
