a piece of string is cut in two at a point selected at random. The probability that the longer piece is at least x times as large as the shorter piece where x>1

< 6 cm to > 26 cm i believe

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.
