The board members of a company think there is a 75% chance of high demand and a 25% chance of low demand for a new product. If the company sells online, research models suggest profits of $20 per unit if there is high demand and $15 per unit if there is low demand. If the company sells through stores, models suggest profits of $50 per unit if there is high demand and –$10 per unit if there is low demand. Is it better to sell online or through stores? Explain. PLEASE HELP ME I'm falling in math class!! ​

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.
