You’re planning to buy a boat , a motor , and some miscellaneous boating equipment. the boat costs $325 , the motor cost $225 , and the equipment cost $ 79 if you’ve saved $438 toward these purchases , how much more do you need to save ?

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.
