Ralph earns $57,345 per year. he earns $10,340 less per year than maureen. how much does maureen earn per year?

tom solved this problem. he said that maureen earns $10,340.

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.
