Janna buys 2 bags of dog food for her dogs .one bag weighs 37 pounds. the other bag weighs 15 pounds. how many pounds do both bags weigh? explain how you solved the problem

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.
