Survival In Nature

Survival, or the act of surviving, is the propensity of something to continue existing, particularly when this is done despite conditions that might kill or destroy it. The concept can be applied to humans and other living things (or, hypothetically, any sentient being), to physical object, and to abstract things such as beliefs or ideas. Living things generally have a self-preservation instinct to survive, while objects intended for use in harsh conditions are designed for survivability.

Meaning

The word, "survival", derives from the Late Latin '' supervivere'', literally meaning "to outlive". Most commonly, "the term 'survival' means physical survival — that is, a struggle to avoid physical extermination". For example, Charles Darwin's theory of natural selection incorporates the concept of the survival of the fittest in the struggle for existence. Darwin defines the biological concept of fitness as reproductive success, so in Darwinian terms the phrase is best understood as survival of the form that will leave the most copies of itself in successive generations.

Historical concepts of survival

Historical references to survival cover aspects ranging from individual survival to that of empires, civilization, and of the human race as a whole. The concept is also applied to non-living and non-physical things. In engineering, the term can be used to mean "the continued ability of the system to perform the desired function". In law, it often refers to a holder of a legal interest who outlives another with whom that interest is shared, such as a surviving spouse, or to the interest itself, such as a right of survivorship. With respect to the human consciousness, particularly when discussed in connection with the concept of a soul or spirit, survival can refer to life after death:

Survival analysis is a branch of statistics for analyzing the expected duration of time until one or more survival-ending events happen, such as death in biological organisms and failure in mechanical systems. One element of survival analysis is the survival rate, the percentage of people in a study or treatment group still alive for a given period of time after diagnosis. It is a method of describing prognosis in certain disease conditions. Survival rate can be used as yardstick for the assessment of standards of therapy. The survival period is usually reckoned from date of diagnosis or start of treatment. Survival rates are important for prognosis, but because the rate is based on the population as a whole, an individual prognosis may be different depending on newer treatments since the last statistical analysis as well as the overall general health of the patient.

Individuals who are concerned with surviving an anticipated catastrophic or apocalyptic event are often grouped within the practice of survivalism. Use of the term ''survivalist'' in this sense dates from the early 1960s.

In popular culture

There are various kinds of media about survival. In both fiction and nonfiction, stories about individuals surviving despite particularly dangerous circumstances are popular. There is also a wide body of educational literature, sometimes referred to as a survival guide, offering advice on survival skills in various dangerous situations such as getting lost without food or water, being attacked, or being in a natural disaster.

In film

In film, the survival film is a genre in which one or more characters make an effort at physical survival, generally while being subject to hazardous conditions or a catastrophic event. It often overlaps with other film genres. It is a subgenre of the adventure film, along with swashbuckler films, war films, and safari films. Survival films are darker than most other adventure films, which usually focus their storyline on a single character, usually the protagonist. The films tend to be "located primarily in a contemporary context" and so film audiences are familiar with the setting, and the characters' activities are less romanticized. In a 1988 book, Thomas Sobchack compared the survival film to romance: "They both emphasize the heroic triumph over obstacles which threaten social order and the reaffirmation of predominant social values such as fair play and respect for merit and cooperation". The author said survival films "identify and isolate a microcosm of society", such as the surviving group from the plane crash in '' The Flight of the Phoenix'' (1965) or those on the overturned ocean liner in '' The Poseidon Adventure'' (1972). Sobchack explained, "Most of the time in a survival film is spent depicting the process whereby the group, cut off from the securities and certainties of the ordinary support networks of civilized life, forms itself into a functioning, effective unit". The group often varies in types of characters, sometimes to the point of caricature. While women have historically been stereotyped in such films, they "often play a decisive role in the success or failure of the group".

In video games

In video games, the survival game, is a subgenre of action video games set in hostile, intense, open-world environments. Players generally begin with minimal equipment and are required to survive as long as possible by crafting tools, weapons, shelters, and collecting resources. These can take the form of survival horror games, which focus on survival of the character as the game tries to frighten players with either horror graphics or scary ambience. Although combat can be part of the gameplay, the player is made to feel less in control than in typical action games through limited ammunition or weapons, health, speed and vision, or through various obstructions of the player's interaction with the game mechanics.

In games operating in a survival mode, or having such a mode as an option, the player must continue playing for as long as possible without dying in an uninterrupted session while the game presents them with increasingly difficult waves of challenges. A variant of the mode requires that the player last for a certain finite amount of time, after which victory is achieved and the mode ends. The mode is particularly common among tower defense games, where the player must improve the defenses of a specific location in order to repel enemy forces for as long as possible. Survival mode has been compared to the gameplay of classic arcade games, where players face off against increasingly stronger waves of enemies. This mode was intended to give the game a definite and sometimes sudden ending, so that other players could then play the arcade game as well.
