1. Adaption refers a change by which an organism or species becomes better suited to its environment. 2. Behavioral adaptions are always heritable, unlike the other kinds of adaptations. 3. Humans normally adapt to environment changes in several ways such as genetic change, developmental adjustment, acclimatization, and cultural practices and use of technology. 4. People relocate to other places or countries in the hope of finding greener pasture and employment opportunities. 5. Migration is defined as the process of geographic mobility, or the change of residence of a person from one community to another. 6. A change in residence within a country is called internal migration. 7. Internal immigrants can be classified as legal immigrants, illegal immigrants and refugees. 8. Transnational migrants as those persons who having migrated from one nation-state to another; live their lives across the borders, participating simultaneously in social relations that embed them in more than one nationstate. 9. The improvement in the quality and availability of communication and transportation options to people makes migration process more complex but fast. 10. Behavioral adaptation is defined as the things organisms do to survive. A change or the process of change by which an organism or species becomes better suited to its environment is called adaptation. This also refers to the action or process of adapting or being adapted or the process of changing to suit different conditions. Adaptations enhance the fitness and survival of everyone. A) Structural adaptations are physical features of an organism such as shape, body covering, armament; and even the internal organization (e.g. a penguin has blubbered to protect itself from freezing temperatures). B) Behavioral adaptations are composed of inherited behavior chains and/or the ability to learn (e.g. bears hibernate in winter to escape the cold temperature and preserve energy). Behavioral adaptation is defined as the things organisms do to survive. Unlike other adaptations, these are not always heritable but are learned. An example of this is the difference between populations of animals that live in the wild and those that live among humans. Wild birds tend to be scared of people, but birds that live in urban areas are often less fearful of people and they even see people as source of food. C) Physiological adaptations permit the organism to perform special functions like venom (in the snakes and the like), secreting slime, phototropism; and more general functions such as growth and development, temperature regulation and ionic balance. This means that adaptation is making adjustments to decisions and activities in order to manage risks and capture potential opportunities brought about by any changes in the environment such as global warming and climate change. The ability of humans to be able to rapidly adapt to varying environment conditions and changes has made it possible for them to survive in any regions or places anywhere in the world. They can normally adapt to environment changes in several ways such as: A) Genetic change is an inherited or acquired modification in organisms that makes them better suited to survive and a particular environment. For instance, people whose ancestors have lived in areas that had endemic, malaria for thousands of years often inherit some degree of immunity to this serious disease. B) Developmental adjustments. This occurs in childhood and typically results in anatomical and/or physiological changes that are mostly irreversible in adulthood. An example of the latter was the now illegal custom in China of tightly wrapping or binding the feet of young girls with cloth in order to hinder normal growth. While this caused permanent, crippling deformities of the foot bones, it also resulted in extremely tiny feet which were considered to be very attractive. Parents crippled their daughters with good intentions. Small feet would make them more attractive marriage partners for rich important men and save them from a life of drudgery. C) Use of technology. Humans do not only interact with their environments biologically. People invented technological aids that allowed us to occupy new environments without having to first evolve biological adaptations to them. Migration People on earth are also facing adaptation challenges borne by the need for mobility. Life has been moving so fast and people as well as changing residences as rapidly. The process of geographic mobility or the change of residence of a person from one community to another with the intention of settling temporarily or permanently is migration. Types of Migration A) International Migration is the permanent transfer of residence from one country to another. It is the change of residence over national boundaries. An international migrant is someone who moves to a different country. International migrants can be further classified as legal immigrants, illegal immigrants and refugee. Legal immigrants are those who moved with the legal permission of the receiver nation. Illegal immigrants are those who moved without legal permission, and refugees are those crossed an international boundary to escape persecution. B) Internal Migration is a change in residence within a country and refers to a change of residence within national boundaries, such as between states, provinces, cities, or municipalities. An internal migrant is someone who moves to a different administrative territory. C) Circulation Migration is a temporary movement of a person. The change in residence is temporary due to work or study, but the migrant will definitely return in his home community. D. Transnational Migration. These are the people who having migrated from one nation-state to another live their lives across borders, participating simultaneously in social relations that embed them in more than one nation-state are called transnational migrants. Not all migrants can be considered as transnational migrants, and not all who take part in transnational practices do so all the time. Most migrants are occasional transnational activists. They more focused on their countries of origin while at others they are more involved in their countries of reception.
