Samantha drives at a rate of 45 mph. Bridget drives at a rate of 70 miles every 2 hours. Who drives faster?

Samantha

Step-by-step explanation: 70 miles every two hours is only 35 mph, so Samantha is faster

step-by-step explanation:

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.
