Recall that the sum of all the angles of a triangle is 180degrees regardless of the size or type of triangle. use the fact and favs about isosceles triangles to answer the following. in which two angles must be equal in this isosceles triangle?

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!

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.
