There are twelve more trucks than cars in the parking garage. the ratio of trucks to cars is 3 to 5. how many trucks and how many cars are there?

There are 18 trucks and 30 cars.

If you want an explanation, leave a comment! Sorry I can't explain it here

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.
