The Survival Of Organisms Depends On Adaptive Behavior And Species Interactions

According to Darwin and his theory on evolution, organisms are presented with nature’s challenge of environmental change. Those that possess the characteristics of adapting to such challenges are successful in leaving their genes behind and ensuring that their lineage will continue. It is natural selection, where nature can perform tiny to mass sporadic experiments on its organisms, and the results can be interesting from extinction to significant changes within a species.

In some communities migration is a kind of rite of passage like marriage. For rural families migration is a survival strategy.

Migration: Animals migrate during certain times of the year, for reasons like food, temperature, or breeding. One example of migration is the migration of Canadian Geese. They migrate to the south in large numbers, for the warmer climate. Once it gets warmer, they begin returning to colder

Fitness is determined by the ability of an organism to survive, grow, and reproduce in a particular habitat. You

Immigration is the movement of people into another country or region to which they are not native in order to settle there, especially as permanent residents or future citizens. Immigrants are motivated to leave their countries for a variety of reasons, including a desire for economic prosperity, political issues, family reunification, escaping conflict or natural disaster, or simply the wish to change one’s surroundings.

Distinguish between the following pairs of terms: kinesis and taxis, circadian and circannual behavioral rhythms, landmarks and cognitive maps, classical and operant conditioning.

1. Evolutionary theory describes how populations change over time due to changes in the gene pool. There are several mechanisms that can change a gene pool and allow evolution to occur. Natural selection, mutation, gene flow and genetic drift are some of the driving forces behind evolutionary change. Natural selection and genetic drift are the mechanisms that decrease genetic variation, whereas gene flow and mutation are the driving mechanism to increase genetic variation. Natural selection is basically the understanding that the environment can not support unlimited population growth, and not all organisms are able to reproduce to their full potential due to trait variation. For example, a black fly may

Words which are compared to immigrant are emigrant and migrant. These three words are similar in the fact that they both include the act of immigration. The difference is that Migration is not a permanent at. When people think of migrant, they think of birds. When a bird migrates, it does not stay at the location permanently, it goes down to usually wait out a climates seasonal change. Emigration is the act of moving somewhere to temporarily live, or work in another country.

1. Adaptations- Characteristics that are passed down from parent to child that increases the organism's chance of survival and reproduction in their environment.

Predation is an interspecific interaction in which one species (the predator) captures, kills, and eats another (prey). Predation removes a prey individual from the population immediately. Different types of predators have different functional responses, meaning they differ in how changes in prey density affect the rate at which they kill prey. The set of alleles that is carried by an individual’s chromosomes is known as genotype. An individual’s observable traits is known as phenotype. Natural selection is a simple mechanism that causes populations of living things to change over time. In fact, it is so simple that it can be broken down into five basic steps: Variation, Inheritance, Selection, Time and Adaptation. Natural selection occurs

In the beautiful nature, the animals and human have demonstrated the variety of their wonderful abilities. The adaptation is one of ability that can be implied as a process of nature that all systems of the body synchronized movements for inducement the body appropriate to the natural habitat, situation, and condition. The adaptation of animals is controlled by internal neural systems [81] and presented in the several forms of deportment. For example, upgrades and downgrades in relationships, shifts in function, or changes in habitat.

In evolutionary biology mathematics is crucial in order to predict the future using equations and formulas.“Evolutionary biology need mathematics for its progress (Maynard Smith, 1982)”. John Maynard Smith was one of the pioneer scientists that introduced mathematical approach to solve evolutionary problems, using the evolutionary game theoretical. EGT uses frequency of the behavioral phenotypes expressed to predict fitness in the population. Fitness payoff of phenotypes depend on frequency of certain trait, if there is equal fitness then there is evolutionary stability in the population. Evolutionary stable strategy (ESS) is a key to study a phenotype in a population because it cannot mutant during natural selection. The most common game used

The dictionary meaning of migration is to movement from one part of something to another. Human migration is the movement of people from one place to another place ( Managalam, 2015).It is of several types such as temporary, permanent, international, internal, voluntary or forced. As the name defined permanent migration is the one in which a person move from his original place or country to another place or country and has no plans to move back to their original home. However, temporary migration is movement from one place to another for limited time. Forced migration is the one in which people have no choice but to move and opposite is true for voluntary migration in which a person make the choice to move out. Internal migration is the movement within the country whereas international migration is the movement from one country to another country(e Schooltoday, 2006). An example of internal migration is the movement of people from Punjab to Haryana whereas an example of international migration is the movement of people from India to Canada.

Migration variations include south to south migrants, south to north migrants, massive internal and transnational migration, slum dwellers, illegal settlements, these grounds, territorial fragmentation, internal displacement, communities and perilous locations.

Fun fact:There is also different types of migration. “Economic migration” is when people are migrating to a country that has a higher percent rate of getting a job. “Social migration” is when you are migrating to start a new life or to live closer to your family. “Political migration” is when people are moving to escape corrupted government or civil war. “Environmental migration” is when natural disasters destroy homes and people try to start a new life in a new country.
