For football tryouts at a local school, 12 coaches and 42 players will split into groups. each group have the same number of coaches and players. what is the greatest number of groups that can be formed? how many coaches and players will be in each of these groups?

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.
