A baseball league manager is sorting out equipment. There are 14 teams of players. Each team has 19 players. Each player will get three baseballs. How many baseballs are needed for the league ?

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.
