Let x = (0, 1] and m = {∅, finite unions of disjoint intervals that are open on the left and closed on the right}. a typical a ∈ m has the form a = sm i=1(ai , bi ], with ai > bi−1. it is easy to see that m is closed under complements and finite unions after noting that the complement of such an interval consists of two disjoint like intervals and the union of two such intervals that overlap is a like interval. the analogous set is not an algebra if x = r - try the complement condition.

were is the equation

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.
