Jake and Carl are deciding what to do after school. They decide to flip two coins. If the coins are both heads, they play video games after school. If the coins are both tails, they watch a movie. If they flip one head and one tail in any order, they ride their bikes. Is this strategy fair? Does each outcome have an equally likely chance of occurring? Why or why not?

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.
