A Jrocey store sells a 6 pack bottled water for 3.75 a 9 pack for 4.50 and a 12 pack 6.89 witch package costs the lest per bottle

ok then what happened.

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.
