What is evolutionary adaptation?
Living organisms are adapted to their environment. This means that the way they look, the way they behave, how they are built, or their way of life makes them suited to survive and reproduce in their habitats.

Organisms are adapted to their environments in a great variety of ways: in their structure, physiology, and genetics, in their locomotion or dispersal, in their means of defense and attack, in their reproduction and development, and in other respects.
Oct 19, 2023 · Organisms can adapt to an environment in different ways. They can adapt biologically, meaning they alter body functions. An example of biological adaptation can be seen in the bodies of people living at high altitudes, such as Tibet. Tibetans thrive at altitudes where oxygen levels are up to 40 percent lower than at sea level.
Oct 19, 2023 · Structural and Behavioral Adaptations. An adaptation can be structural, meaning it is a physical part of the organism. An adaptation can also be behavioral, affecting the way an organism responds to its environment. An example of a structural adaptation is the way some plants have adapted to life in dry, hot deserts.

About this unit
In this unit, you'll learn about how species evolve and adapt to their surroundings. From the way populations change to survive in new environments, to the fascinating processes of speciation and extinction, you'll gain a deeper understanding of the natural world and the forces that shape it.
Natural selection and adaptation
What determines an adaptation's success? Natural selection is the unflinching process of answering that question.

When the environment changes, some species roll with the punches; that's adaptation!
When ecosystems change, species change. Some decline or go extinct, and sometimes new species emerge. How does this happen?
Dodos and ground sloths and mammoths, oh my! What factors can lead a species to extinction?
Aug 15, 2023 · Define osmoregulation and describe this process in animals and plants. Describe metabolic pathways that release or store energy. List elements required by living organisms. Provide examples of evolutionary trade-offs with regards to the acquisition of nutrients and energy.
Oct 19, 2023 · An adaptation is a mutation, or genetic change, that helps an organism, such as a plant or animal, survive in its environment. Due to the helpful nature of the mutation, it is passed down from one generation to the next. As more and more organisms inherit the mutation, the mutation becomes a typical part of the species.
