Aship travels due west for 83 miles. it then travels in a northwest direction for 111 miles and ends up 165 miles from its original position. to the nearest tenth of a degree, how many degrees north of west did it turn when it changed direction? (show your work? 25 points? )

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.
