The process of evolution involves changes in the genetic makeup of a population over a period of time. Sexual reproduction enhances variability among offspring. The random alteration of DNA from parent to offspring, called mutations, also produces variable characteristics in offspring. Some mutations can be helpful, while others can be harmful and hinder survival. In this experiment, students mimicked random mutations. Data was collected to determine if the mutations were helpful or harmful when trying to collect and eat food. Collection of 15 pieces of candy was ideal and needed for survival.
Consider the mutations to the appendages and digits. Which mutation would MOST LIKELY result in the extinction of that group of organisms?
A. Group A long nails
B. Group D hands fused
C. Group H short legs
D. Group B paddle hands
