A population of white, grey, and black lizards lives on a volcanic island, and each phenotypic color has an equal chance of surv
ival. However, after the latest volcanic eruption, 75 percent of the island was covered with volcanic ash and hardened lava flows. This event caused the black lizards to be naturally selected
over the white and grey lizards. This change is an example of what type of microevolution?
A) stabilizing selection
B) normal distribution
C) directional selection
D) disruptive selection
I would say disruptive selection, because the sudden eruption of the volcano disrupted the circumstances of the lizards, allowing the black ones to survive better because of camouflage against the black rock.
