Alice had 3 1/4 pounds of flour at the beginning of the week. At the end of the week, she had 4 2/3 pounds. how much has she used?

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.  

ok thats very interesting
