The sum of two numbers is 129. The first number is 3 more than twice the second number. What are the two numbers?

99 30

Step-by-step explanation:

i think this should be it.

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.  

i hope this is what you were looking for.
