James is setting up a fish tank. he is buying a breed of goldfish that typically grows to be 12 inches long . it's recommended that there be 1 gallon of water for every inch of fish length in the tank . what is the recommended ratio of gallons of water per fully grown gold fish in tank ?

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.
