The population of rabbits on an island is growing exponentially. In the year 2005, the population of rabbits was 6900, and by 2012 the population had grown
to 13500.
Predict the population of rabbits in the year 2015, to the nearest whole number.

the answer is b.)

< 1=< 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.
