Adaptation is the process by which living organisms adjust to their environment over time. This can involve physical changes, such as the development of thicker fur in polar bears to survive in cold climates, or behavioral changes, like birds migrating to warmer areas during winter. These adjustments help species survive and reproduce in their specific habitats. In addition to biological adaptation, the term can also refer to how individuals or groups adjust to new situations or challenges. For example, humans may adapt to technological advancements by learning new skills or changing their daily routines to incorporate new tools and methods.
