Survive
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 ...

Survival Of The Fittest
"Survival of the fittest" is a phrase that originated from Darwinian evolutionary theory as a way of describing the mechanism of natural selection. The biological concept of fitness is defined as reproductive success. In Darwinian terms, the phrase is best understood as "Survival of the form that will leave the most copies of itself in successive generations." Herbert Spencer first used the phrase, after reading Charles Darwin's '' On the Origin of Species'', in his ''Principles of Biology'' (1864), in which he drew parallels between his own economic theories and Darwin's biological ones: "This survival of the fittest, which I have here sought to express in mechanical terms, is that which Mr. Darwin has called 'natural selection', or the preservation of favoured races in the struggle for life." ^ "Herbert Spencer in his ''Principles of Biology'' of 1864, vol. 1, p. 444, wrote: 'This survival of the fittest, which I have here sought to express in mechanical terms, is that ...

Survivalism
Survivalism is a social movement of individuals or groups (called survivalists or preppers) who proactively prepare for emergencies, such as natural disasters, as well as other disasters causing disruption to social order (that is, civil disorder) caused by political or economic crises. Preparations may anticipate short-term scenarios or long-term, on scales ranging from personal adversity, to local disruption of services, to international or global catastrophe. There is no bright line dividing general emergency preparedness from prepping in the form of survivalism (these concepts are a spectrum), but a qualitative distinction is often recognized whereby preppers/survivalists prepare especially extensively because they have higher estimations of the risk ( odds) of catastrophes happening. Nonetheless, prepping can be as limited as preparing for a personal emergency (such as a job loss, storm damage to one's home, or getting lost in wooded terrain), or it can be as extensive ...

Survival Analysis
Survival analysis is a branch of statistics for analyzing the expected duration of time until one event occurs, such as death in biological organisms and failure in mechanical systems. This topic is called reliability theory or reliability analysis in engineering, duration analysis or duration modelling in economics, and event history analysis in sociology. Survival analysis attempts to answer certain questions, such as what is the proportion of a population which will survive past a certain time? Of those that survive, at what rate will they die or fail? Can multiple causes of death or failure be taken into account? How do particular circumstances or characteristics increase or decrease the probability of survival? To answer such questions, it is necessary to define "lifetime". In the case of biological survival, death is unambiguous, but for mechanical reliability, failure may not be well-defined, for there may well be mechanical systems in which failure is partial, a matter of d ...

Self-preservation
Self-preservation is a behavior or set of behaviors that ensures the survival of an organism. It is thought to be universal among all living organisms. For sentient organisms, pain and fear are integral parts of this mechanism. Pain motivates the individual to withdraw from damaging situations, to protect a damaged body part while it heals, and to avoid similar experiences in the future. Most pain resolves promptly once the painful stimulus is removed and the body has healed, but sometimes pain persists despite removal of the stimulus and apparent healing of the body; and sometimes pain arises in the absence of any detectable stimulus, damage or disease. Fear causes the organism to seek safety and may cause a release of adrenaline, which has the effect of increased strength and heightened senses such as hearing, smell, and sight. Self-preservation may also be interpreted figuratively, in regard to the coping mechanisms one needs to prevent emotional trauma from distorting the mind (s ...

Survivability
Survivability is the ability to remain alive or continue to exist. The term has more specific meaning in certain contexts. Ecological Following disruptive forces such as flood, fire, disease, war, or climate change some species of flora, fauna, and local life forms are likely to survive more successfully than others because of consequent changes to their surrounding biophysical conditions. Engineering In engineering, survivability is the quantified ability of a system, subsystem, equipment, process, or procedure to continue to function during and after a natural or man-made disturbance; for example a nuclear electromagnetic pulse from the detonation of a nuclear weapon. For a given application, survivability must be qualified by specifying the range of conditions over which the entity will survive, the minimum acceptable level or post-disturbance functionality, and the maximum acceptable downtime. Military In the military environment, survivability is defined as the abili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Survival Skills
Survival skills are techniques that a person may use in order to sustain life in any type of natural environment or built environment. These techniques are meant to provide basic necessities for human life which include water, food, and shelter. These skills also support proper knowledge and interactions with animals and plants to promote the sustaining of life over a period of time. Survival skills are often associated with the need to survive in a disaster situation. Survival skills are often basic ideas and abilities that ancient people invented and used themselves for thousands of years. Outdoor activities such as hiking, backpacking, horseback riding, fishing, and hunting all require basic wilderness survival skills, especially in handling emergency situations. Bushcraft and primitive living are most often self-implemented but require many of the same skills. First aid First aid ( wilderness first aid in particular) can help a person survive and function with inju ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English natural history#Before 1900, naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a Common descent, common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this Phylogenetics, branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by Burials and memorials in Westminster Abbey, burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh Medical School, ...

Natural Selection
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which in his view is intentional, whereas natural selection is not. Variation exists within all populations of organisms. This occurs partly because random mutations arise in the genome of an individual organism, and their offspring can inherit such mutations. Throughout the lives of the individuals, their genomes interact with their environments to cause variations in traits. The environment of a genome includes the molecular biology in the cell, other cells, other individuals, populations, species, as well as the abiotic environment. Because individuals with certain variants of the trait tend to survive and reproduce more than individual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Right Of Survivorship
In property law, a concurrent estate or co-tenancy is any of various ways in which property is owned by more than one person at a time. If more than one person owns the same property, they are commonly referred to as co-owners. Legal terminology for co-owners of real estate is either co-tenants or joint tenants, with the latter phrase signifying a right of survivorship. Most common law jurisdictions recognize tenancies in common and joint tenancies. Many jurisdictions also recognize tenancies by the entirety, which is effectively a joint tenancy between married persons. Many jurisdictions refer to a joint tenancy as a joint tenancy with right of survivorship, but they are the same, as every joint tenancy includes a right of survivorship. In contrast, a tenancy in common does not include a right of survivorship. The type of co-ownership does not affect the right of co-owners to sell their fractional interest in the property to others during their lifetimes, but it does affec ...

Life After Death
The afterlife (also referred to as life after death) is a purported existence in which the essential part of an individual's identity or their stream of consciousness continues to live after the death of their physical body. The surviving essential aspect varies between belief systems; it may be some partial element, or the entire soul or spirit of an individual, which carries with it and may confer personal identity or, on the contrary, nirvana. Belief in an afterlife is in contrast to the belief in oblivion after death. In some views, this continued existence takes place in a spiritual realm, while in others, the individual may be reborn into this world and begin the life cycle over again, likely with no memory of what they have done in the past. In this latter view, such rebirths and deaths may take place over and over again continuously until the individual gains entry to a spiritual realm or otherworld. Major views on the afterlife derive from religion, esotericism an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spirit (animating Force)
In folk belief, spirit is the vitalism, vital principle or animating essence within all life, living things. As recently as 1628 and 1633 respectively, both William Harvey and René Descartes still speculated that somewhere within the body, in a special locality, there was a "vital spirit" or "vital force", which animated the whole bodily frame, just as the engine in a factory moves the machinery in it. Overview People have frequently conceived of spirit as a supernatural being, or non-physical entity; for example, a demon, ghost, fairy, or angel. In ancient Islamic terminology however, the term ''spirit'' (''rūḥ''), applies only to "pure" spirits, but not to other invisible creatures, such as jinn, Shaitan, demons and angels in Islam, angels. Historically, spirit has been used to refer to a "subtle" as opposed to "gross" material substance, as put forth in the notable last paragraph of Sir Isaac Newton's ''Philosophiæ Naturalis Principia Mathematica, Principia Mathematica ...
