Ineed figuring out how to get this from 20 people to thirty people.
attached is the problem

you simply add an additional half of the entire recipe

Step-by-step explanation:

1/4 cup butter

2/3 cup sugar

So on so forth...

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.
