Jeremy can type 140 words in 4 minutes and 525 words in 15 minutes. let x= minutes spent typing and y= words typed. what is the rate of change of y with respect to x

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.
