Which term describes the evolutionary process through which an organism becomes better suited to its environment?

• A. Adaptation
• B. Evolution
• C. Fossil record
• D. Isotonic

Answer: (A)

Adaptation is the process by which an organism becomes better suited to its environment. It happens when heritable traits improve survival or reproduction and become more common in a population over generations through natural selection. For example, moths that blend with their surroundings survive longer, so the traits that help camouflage become more frequent. Evolution refers to the broader changes in a population’s genetic makeup over time and isn’t the specific process of an individual becoming better suited. The fossil record shows evidence of evolutionary change, not the mechanism, and isotonic is unrelated.
