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 and the ability to collect and eat food. Each experimental group was timed for both collection and eating of the food, and data was collected to determine if the mutations were helpful or harmful when trying to collect and eat food.
Of all the mutations, we can conclude that one mutation would MOST LIKELY contribute to a rapid rate of extinction. That is
