The isosceles triangle has two sides with the same length. the base is one-half the length of a side. the expression which represents the perimeter, the distance around the triangle, is s+s+1/2s . what is the value of this expression if s=8

s+s+1/2s

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.
