What is Adaptation? Theory, Types, and Its Importance


What is Adaptation?

Adaptations are features that improve an organism’s chances of survival. These are usually functional features that are maintained through development and natural selection and are passed down through later generations. Adaptation occurs in plants and animals that help them adapt to the environment.

What is Adaptation Theory?

In general, we know the principle of compatibility as the existence of fit. It is the ability of an organism to adapt to the environment over time. Charles Darwin, who experimented in the Galapagos Islands in the 1830s, was a scientist who went with his theory.

Even before Darwin, many scientists, such as Empedocles, Aristotle, William Paley, Lamarck, and Buffon, acknowledged the fact that the species changed over time. But the root cause of this change was not understood or this adjustment was a continuous process that was not finalized.

The adaptation theory suggested that three other reforms were taking place along with environmental monitoring: environmental monitoring, genetic modification, and extinction.

Habitat tracking: Habitats search for environments such as the habitat in which they live.

Extinction: When species are unable to adapt, migrate, or find a new environment to live in, they eventually become extinct and become extinct.

Genetic change: Genetic mutation is a natural selection that allows an organism with small mutations to tolerate organisms in a particular area compared to other organisms.

Example: Darwin focused on turtles living on two shores. On one island, turtles were fed from small floors because they had small arms and flat shells.

When these turtles migrate to another island, when the supply of energy is high, the tortoises with larger organs can eat, live and reproduce.

His tail also grew larger by the moment. Their shells were circular, and for the island’s turtles, these changes lasted for centuries.


What are the different types of adaptation?

types of adaptation

Structural Adaptation

Structural adjustments are changes in the structure of an organism to adapt better to the environment.

It is related to the physical characteristics that develop in an organism. These strengthen the ability to survive in the wild, but take a long time to fully prepare.

Example: How desert plants adapt to desert conditions with very little water available and high temperatures. In addition, plants collect their own water as a solution to the declining water supply and exploit it according to desert conditions.

Many butterflies and insects are good examples. The Brimstone Butterfly is green, so it completely obscures many plants in nature. It is able to repel predators in nature. Along with feathers that mimic dead leaves, is another great example.

Structural adaptation of plants can be seen in cactus. Cactus wax coating and a strong backbone, often found in arid deserts. Instead of leaves, make spine sheds for the cactus so that they are less waterlogged and cooler in hot weather. The cactus’ thick waxy coating also helps to retain water, allowing it to survive with less rainfall.

Habitat change

When an environment changes, there is no other way but to adapt to animals and plants. This can happen by adopting their diet and lifestyle to find a suitable environment or to support themselves in the newly changed environment.

Example: If the average temperature is cold, new organisms need to find new ways to stay warm. They can grow fur to keep themselves warm.

Genetic modification

This is related to Darwin’s Finch experiment. Genetic modification can occur due to natural selection. This allows a particular gene to be more easily transmitted due to a better survival rate that gene.

Example: As for the finches, any genes made them the most suitable peaks for their particular island, which meant that they were likely to live longer because they would get the food they needed. This means that birds with well-matched beaks are able to breed more. When they reproduce, they pass on the genes that make up their easy peaks. Thus the cycle continued with each new generation.

Behavior Adaptation

Behavioral adaptation is a change in the behavior of an organism to better survive in an environment.

Example: Migratory birds migrate west in summer due to the availability of more meat.

Physiological Adaptation

Physical adaptation is a method of the brain that helps an organism to survive and reproduce better in an arrangement. These changes may be different ways in which an organism responds to environmental stimuli.

Example: To reduce heat absorption, an animal living in colder areas may have features such as dense fur and short legs. This vibration is the physical adaptation to generate more heat when heated.


Co-adaptation occurs when two or more species coexist and coexist.

This is when the two species adapt to help each other survive. The existence of one is strictly related to the existence of another. Bees and flowers are an example of this, where bee nectar (food), flowers depend on bee pollination.

Example: Humming bees have long peaks that help the bird capture nutrients from specific crops.

Humans and trees are other examples, where trees breathe oxygen and absorb carbon dioxide, allowing humans to breathe oxygen and breathe with carbon dioxide. You can think of co-adaptation as effective teamwork that helps you survive and thrive on everything in the natural world.


This is when one animal adapts to imitate another species to help it survive. For example, the hoverfly, a harmless bug that looks like a lizard, carries the warning colors black and yellow. Other animals, including our humans, believe it is a lizard and will stay away because of its sting. This increases the chances of flying by hand.


Why do adaptations in plants and animals occur?

adaptations in plants and animals

Plants and animals adapt to their surroundings for better survival. There are two opposing views around adaptation, which philosophers and natural historians argue. Regardless of the ability of life to survive, it naturally becomes more complex and conducive to further achievement.

On the other hand, some believe that optimization is the ultimate goal. Once an animal has survived and thrived in its environment, there is no need for further adaptation.

In practice, plants and animals are ideal for survival. We can see this with Charles Darwin’s Finch. This is a study of finches living on various islands in the Galapagos. Over 40 years of observation, each evolved character evolves to survive on its own island. These are excellent optimization examples to help you understand how and why adaptation occurs.

On some islands, more insects were found in trees in bars. Over time, high and thin peaks developed on these islands. This provided a great tool to catch and eat these insects in such a way that they could climb on the bill. Being able to feed them gives them a better chance of survival, which means that the genes with longer and thinner beaks are passed on.

What is the importance of adaptation?

Adaptation is essential for the survival of organisms. Animals that do not adapt to changing environmental changes are dying. These adaptations are the result of genetic mutations. Surviving animals pass on the mutated genes to their offspring. This is called natural selection.

Adaptations such as forgetfulness and dye protect them from predators. DNA mutations allow animals to live longer in dangerous environments and pass on these signs of survival to future generations. These adaptations allow different types of organisms to thrive on earth.

Charles Darwin studied turtles on two islands. The turtles on an island had legs and straight shells and food underground. Some turtles migrated to another island with a lot of food. The long-legged turtle survived. Their necks stretched out, and over time the shells became round. Thus, the population of the new island increased as it matched its species.

The concept of adaptation becomes easy to understand once it is explained through proper examples. The experts at Takshila learning make it very simple for the aspirants to understand and apply it in their daily and professional life.
