Which of the following does not illustrate adaptation to the environment ?
Answer Details
The option that does not illustrate adaptation to the environment is "Development of big muscles by a weightlifter."
Adaptation refers to a trait or characteristic that helps an organism survive and reproduce in its environment. The other options listed all describe physical features that have evolved over time to help organisms survive in their environments.
Color changes by a chameleon help it blend into its surroundings and avoid predators or catch prey. The streamlined shape of fishes helps them move through water more efficiently and catch prey. Light bones in birds help them fly more easily. Possession of fins by fishes helps them swim and maneuver in water.
On the other hand, the development of big muscles by a weightlifter is a conscious choice that has nothing to do with survival in the natural environment. While weightlifting may help an individual become stronger, it is not a biological adaptation that has evolved over time in response to environmental pressures.
