43 k(n) = k(n-1)-1; k(1) = 2
44 h(x) = (4)
45 g(n) = in-4
46/(x) = f(x - 1). 2; f(0) = 2

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.  

a - base

b - exponent
