Abasket of beads contains 8 red beads 6 yellow beads and 6 green beads. a bead will be drawn and replaced 150 times. what is a reasonable prediction for the number of times a green bead is drawn

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.
