Adaptations

An adaptation is any advantageous structural or functional characteristic developed over time that enables a living organism to survive, reproduce, and constantly adjust to its specific changing environment.

• According to Darwin’s natural selection theory, only the most viable and adaptable species successfully survive the struggle for existence.
• The continuous adjustment of a species to its new surroundings serves as the primary factor driving the formation and conservation of species.
• Organisms that are unable to adjust to shifting environmental conditions will gradually diminish in the course of evolution and eventually face extermination.
• These constant structural and functional adjustments directly match living forms to their changing environment, ensuring their survival within specific ecological limits.
