Introduction: Evolution and the Foundations of Biology

Overview: Inquiring About Life

Biology is the scientific study of life, focusing on understanding the diversity and unity of living organisms. Evolution is the central theme that explains both the adaptations of organisms and the vast variety of life forms on Earth.

• Adaptations: Traits that enhance an organism's ability to survive and reproduce in specific environments. Example: The light, dappled fur of a beach mouse helps it blend into sandy surroundings, while inland mice of the same species have darker fur to match their environment.

• Evolution: The process of change in populations of organisms over generations, leading to the diversity of life observed today. It is the fundamental principle of biology.
