Awhile back, either james borrow $12 from his friend rita or she borrowed $12 from him, but he can't quite remember which. either way, he's planning to pay her back or ask but she pay him back this afternoon. if she has $42.80 in his wallet, which equation represents the amount of money he may have after he sees rita?

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.
