Adaptation is the process by which a species becomes fitted to its environment through natural selection. Learn about different types of adaptation, such as physiological, genetic, and functional, and see examples from animals and plants.

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...

Adaptation affects all aspects of the life of an organism. The following definitions are given by the evolutionary biologist Theodosius Dobzhansky: 1. Adaptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats. 2.
ADAPTATION definition: 1. the process of changing to suit different conditions: 2. the process in which a living thing…. Learn more.
Oct 19, 2023 · In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. Although scientists discussed adaptation prior to the 1800s, it was not until then that Charles Darwin and Alfred Russel Wallace developed the theory of natural selection.
Jun 3, 2012 · The meaning of ADAPTATION is something that is adapted; specifically : a composition rewritten into a new form. How to use adaptation in a sentence.
Jan 30, 2024 · Adaptation refers to a wide range of measures to reduce vulnerability to climate change impacts, from planting crop varieties that are more resistant to drought to enhancing climate information and early warning systems to building stronger defences against floods.
