Question

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.

Which mutation provided an advantage for food collecting, but was detrimental when it came to food eating?

A Group A long nailsGroup A long nails
B Group B paddle handsGroup B paddle hands
C Group D hands fusedGroup D hands fused
D Group E webbing on hands and feet

Answer 1

D — Group E webbing on hands and feet.

Reason: Webbing increases surface area for scooping/swimming so it helps collect food, but it reduces finger separation and fine motor control, making it harder to grasp and manipulate food for eating.
