Structural adaptations are the changes that occur constantly in the structures of the bodies of internal and external organisms so that the organism can keep pace with what is happening around it, it has been known for millions of years that the Earth is not at the same pace in climate and changes that constantly occur in air and water as well as rocks, if you are a fan of geology, you will know that the Earth came on it a lot of diverse geological ages such as ice and desert ages, each of which was characterized by some things such as climate.
The climate participated in the inability of many living organisms to adapt to these changes, which led to the extinction of some species and the emergence of others to adapt to new changes on Earth and this is one of the ways in which animals and organisms of all kinds adapt to changes, there are species that are extinct and other species that change in their forms through some internal and external changes, including those who flee and migrate to a safer place for him, his family, his species, and a place where he can establish his home and coexist with the conditions of Similar to what he lived in, and one of the most prominent methods used, despite their abundance, is the appearance of some structures in the bodies of living organisms.
Adaptations of various kinds are special physical characteristics and features, or characteristics in the behavior of organisms or changes in the genes of living organisms that help these organisms when changing the environments on which they relied for a period of time to survive in the same environment in which this change occurred, and one of the famous adaptations is structural adaptations, which mean the emergence of renewed shapes and colors on the organism.
The change can appear in the form of a change in the color of the breed over the course of an entire generation or a change in shape with the appearance of appendages, for example, and the emergence of these adaptations is explained to a group of mutations that occur over generations that create a severe contrast between these generations and previous generations, and these mutations can cause apparent changes in shapes, in the functions of different organs, body chemistry or behavior, and mutations usually continue until they are fixed in a certain shape and organisms continue to do so It makes a new change and then changes in form and function again.
Ways organisms deal with environmental changes
- Track similar environments.
- Extinction.
- Adjustment.
Changes occur constantly, some of which happen with prior warnings and some of which happen without warning, but living organisms know these warnings and change based on them, I mean that they feel the change and begin to take the necessary precautions that they deem appropriate to face these changes, and the ways in which living organisms deal with changes differ and these methods are:
Tracking similar environments: When living organisms begin to feel change and that their body will not be able to adapt to new conditions, they begin to search for similar environments in the conditions in which they lived, because they will not be able to adapt to new conditions, and this is a method taken by many living organisms, and it can also happen on normal days, there are species of fish that migrate in certain seasons because the current places do not suit the vital processes, and often the breeding season because the current place does not suit them, Then you come back to it again after the end of this season
Extinction: There are animals that have become extinct over millions of years because they have not been able to adapt to new environments and climate changes, as well as their motor and physiological ability to go out to places and environments similar to their old environments in which they lived.
Adaptation: Adaptation is our topic in this article, or it can be described as genetic changes and occurs until organisms are selected that can continue, there are organisms whose bodies can form mutations that give them new changes through which they can continue in the same environment and survive, and other organisms that cannot do this and become extinct.
Different types of adaptations
- Modular adaptations.
- Physiological adaptations.
- Behavioral adaptations.
Adaptations or the adaptation process is a selection process from among living organisms for organisms that will complete the life cycle and adapt to new environmental changes, and other organisms die, as there are environments in which competition between organisms is intense for the few resources that are not available, so organisms outperform other organisms, for example in desert environments, organisms and plants that have formed appendages continue to enable them to continue in the difficult desert environment, and there are several types of adaptations, namely:
Structural adaptations: Structural adaptations are also called structural adaptations because they are changes in the structure of the body itself, and structural adaptations are very visible because they are redundant in the body or change in color and so on, and occur until the organism adapts better to the environment, and structural adaptations can only indicate total changes in the body of the organism that help it to stay in its environment itself and not have to leave and there are many examples of structural and structural changes.
Animals with dense fur that live in the Arctic are among these examples, as these animals have different types of thick fur that protect them from the very cold temperature, and vice versa we do not see this fur in tropical animals because each animal adapts according to the environment in which it is located and its changes, and examples are also fats that are found in many marine animals that protect them from cold, whether it is cold air or water, such as whales and dolphins.
Physiological adaptations: Physiological adaptations are the second type of adaptations made by living organisms to overcome the change of their environment, which are processes carried out by the body of the organism to adapt to changes and it is possible that this process is the only way that the organism can adapt through it and physiological adaptations are usually invisible because they are changes that occur within the organs of the body only and are not seen, but these changes appear in the form of signs Abbreviated only in different body functions
Behavioral adaptations: Behavioral adaptations are the last type of adaptations, where adaptation is made when a type of living organism develops in order to survive, and behavioral adaptations are by changing some behaviors in the way of living or changing the way something is done that was known to be done in a certain way and so on, and it is one of the famous types of adaptations that many living organisms can do.
Another example of behavioral adaptation is the migration in order to survive at specific times of the year, where approximately 40% of different bird species undergo migration for vast distances and heights until certain seasons and after their end they return to their original habitat As they were before, this is for birds, there are certain types of insects that also migrate, especially in winter, but unfortunately they have a very short lifespan that they cannot return to their original habitat again.
