- Adaptation, in biology, the process by which a species becomes fitted to its environment; it is the result of natural selection’s acting upon heritable variation over several generations. Organisms are adapted to their environments in a variety of ways, such as in their structure, physiology, and genetics.

In Humans:
Long hours of exposure to the sun results in a tan. As the exposure to heat and UV rays increases, the melanocytes present in the skin ramp up the production of melanin. This pigment helps to absorb the heat and protects the nucleus, thus protecting the DNA from mutation due to UV radiation. Hence, the process of tanning represents how our body adapts to the heat and UV radiation from the sun. Example 2: In high-altitude environments, the human body signals an increase in the production of re...
In Animals:
Animals living in extremely cold environments have thick fur and fat around their body to provide insulation. Pregnant polar bears bulk up on fat before the winter. This is an adaptation that helps them survive the harsh winter where food is very scarce. Sometimes, adaption is often mistaken for evolution, though both are very different processes. Evolution brings about drastic changes that occur in the genetic level, whereas adaptation is a short-term process where the changes that occur are...
Giraffe
Giraffes are the tallest land mammals today, but they weren’t so tall a few million years ago. During the Miocene Epoch, nearly 25 million years ago, the earliest giraffe ancestor was the size of a modern red deer. It did not have a long neck, nor long legs like its modern-day relatives. However, the competition for food with other herbivores was rather stiff. However, the leaves in the taller shrubs and trees was an untapped niche. But only the animals with longer necks were able to graze on...
These are special attributes that involve some parts of an organism’s body, such as skin, colour and shape. These adaptations help the organisms to survive in their natural habitat. Examples include the blubber of a whale, the beak of a woodpecker, baleen of a humpback whale.
These are mechanisms present in an organism that allow it to perform certain biochemical reactions to survive in its natural habitat. Example: A snake’s ability to produce venom, mammal’s ability to maintain constant body temperature. Even the ability of our body to produce hydrochloric acid to digest food is considered as a physiological adaptatio...
These are ways a particular organism behaves to survive in its natural habitat. Migration of animals and birds are considered as a behavioural adaptation. Hibernation and aestivation are also behavioural adaptations. The most significant animal adaptations entirely depend on the type of habitats they are found in. The earth has several natural envi...
Learn about the animal adaptations and its types. Adaptations could be PHYSICAL, PHYSIOLOGICAL, or BEHAVIORAL. All living things (including humans) on this planet have adaptations.
Aug 25, 2024 · What is adaptation of animals? The adaptation of animals and plants to their environment is a series of varied biological processes with varying purposes, but the general purpose is the continued survival of the species. This is key to the difference between an animal's adaptation and ability.
Oct 19, 2023 · process by which organisms that are better -adapted to their environments produce more offspring to transmit their genetic characteristics. Evolutionary adaptation, or simply adaptation, is the adjustment of organisms to their environment in order to improve their chances at survival in that environment.
An adaptation is a characteristic that helps an animal survive in its habitat. All animals must be able to obtain food and water, protect themselves from harm, withstand the climate, and reproduce young so the species doesn't become extinct.
Animals including earthworms, beavers and humans use some of their adaptations to modify their surroundings, so as to maximize their chances of surviving and reproducing. Beavers create dams and lodges, changing the ecosystems of the valleys around them.
