Assuming that species I is the ancestral species of the group, explain the most likely genetic mutation that produced the polypeptide in species II and the most likely genetic mutation that produced the polypeptide in species III. (30 points)

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."

multiply it by 5 in order for you to understand i cant give an exact answer.
