Suppose that the number of pairs of clothes purchased in a year by Europeans is normally distributed and the mean number of clothes is 10 a year. Suppose that a researcher takes 2,950,000 samples of Europeans, and each sample consists of 1000 Europeans. She asks each European how many pairs of clothes they buy in a year. She then calculates a mean for each of the 2,950,000 samples. If she added up the mean for each of the 2,950,000 samples, and divided by 2,950,000, what would be answer that she would obtain? Explain the answer.

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.
