Carlos had 28 baseball cards. the cards came in packs of 4. carlos gave his friend 3 packs of cards. write an equation using c for the number of baseball cards left. solve to find how many baseball cards carlos has left.

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.  

hope this !

let me know
