When we talk about evolutionary processes, the usage of the phrase “Survival of the fittest” has been very common in evolution and biology. It depends on how well one performs and how “fit” the individual is in the cut-throat competitive world. When asked what the survival of the fittest means in humans, a layman might understand the ordinary usage. But in biology, we need vĩ đại understand how this phrase came into existence and became ví important in the biological world. Read on vĩ đại learn what survival of the fittest is in biology…

Survival of the Fittest Definition

In biology, the definition of survival of the fittest is this, “a natural process resulting in the evolution of organisms best adapted vĩ đại the environment”. The origin of this phrase is from the evolutionary theory proposed by Charles Darwin, an English naturalist and evolutionary biologist. He used this phrase vĩ đại describe how the natural process of selection works and how the existence of different biological organisms is taken care of by the forces of nature.

Meaning of fitness from a biological perspective

When we talk about fitness from the biological perspective, it’s not solely the physical fitness that we emphasize, but reproductive fitness and reproductive success serve as crucial deciding factors for overall fitness. When evolutionary biologists use this term, they tend vĩ đại convey the meaning that a biologically fit organism is expected vĩ đại leave as many (maximum) progenies as possible. Leaving more progenies ensures that the maximum copies of an organism continue vĩ đại inhabit the Earth even when that parent individual organism ceases vĩ đại exist (after its death). Such fitness, in all its totality, takes care of the “species continuation” BUT with “the best ren pool”.

Interpreted as Expressing a Biological Theory

When we are asked vĩ đại explain natural selection and survival of the fittest in the subject of Biology, we take forward the concept of biological or reproductive fitness. In contrast vĩ đại the fit individuals or species, unfit individuals or species don’t pass the test of producing enough copies of their own.

Even though we tend vĩ đại commonly use this phrase up vĩ đại the individual level, such evolutionary processes usually play out their roles that are ‘observable and significant’ at the species level. And even the effect of this selection of the fittest is reflected at the species level. When we talk in a more scientifically aligned manner, “reproductively fit” means those inheritable characters that empower a species vĩ đại amp up and boost its chances of producing “the fittest” generation, year after year, decades after decades, era after era, and ví on…

To make it further clearer for you vĩ đại understand, let’s take the example of viruses. The survival of the fittest in the virus world depends on those trans-generationally inheritable attributes that endow a virus with the ability vĩ đại produce more viruses (higher viral load) with more virulence than vãn the parental generation virus.

How This ‘Survival of the Fittest’ Phrase Came Into Existence

Charles Darwin drafted and published his writing called “Principles of Biology” in 1864. In this writing, there was one of his now-acclaimed and highly well-received segments by the scientific community on “On the Origin of Species”. It was after reading this writing of Darwin and drawing parallels between Darwin’s biological theory and his own economic theory that a well-renowned philosopher Herbert Spencer introduced the Survival of the fittest. He further strained the connection of biological natural selection introduced by Darwin vĩ đại his economic theories. And this came into the limelight when Herbert Spencer connected his survival of the fittest vĩ đại Darwin’s natural selection concept.

It was Alfred R. Wallace who suggested vĩ đại Charles Darwin vĩ đại use this phrase introduced by Spencer in the biological world. Then, Charles Darwin adopted the usage of this phrase in place of natural selection. Additionally, he introduced and totally replaced the use of natural selection and published these changes in “The Variation of Animals and Plants Under Domestication” in 1868. Also, in the 5th edition of the “On the Origin of Species” (1869), Charles Darwin introduced the survival of the fittest phrase and explained it as the mechanism of nature vĩ đại design more efficient, fine-tuned, and better-selected individuals with the optimum ren pool for a specific immediate and local environment.

So, this is how a phrase ví commonly used by biologists and laymen came into existence. It traversed paths ranging from the economical schools of thought vĩ đại the biological arena.

How is ‘Survival of the Fittest’ Phrase Used in Evolutionary Theory

In evolutionary biology, nothing is absolute; everything that is affected by the forces of nature is always relative. Along the same line, Darwin explained all the processes of evolution including ‘the survival of the fittest’ (Darwinism survival of the fittest) as relative and not absolute. He elaborated that the same species that is the best performer and the fittest under a given phối of conditions can be lost vĩ đại extinction under a different phối of environmental conditions. If you take a look at the fittest of the species that have gone extinct now, you can come vĩ đại know that reproductive fitness is also not absolute. It depends heavily on the environmental factors prevailing in a location at a given point in time.

One of the easiest examples (survival of the fittest examples) is the wooly mammoths. Once the fittest (both physically and reproductively) among all the other biological beings on the Earth, the wooly mammoths vanished from the face of the planet Earth some 1000 years after their evolution. This is a clear depiction of nothing being absolute in space and time. Everything, even the fittest population is the topmost only in a defined phối of conditions and factors.

Interpreted as Expressing a Moral Theory

This survival of the fittest phrase can be interpreted from a different perspective than vãn the biological sense. When expressed as a moral theory, it is linked vĩ đại the role this phrase serves and points vĩ đại in the social dimension of life. Let’s look at it in a point-wise manner.

Social Darwinists

The theory of social Darwinism explains that the different ethnic groups, classes, and races of human beings are influenced and subject vĩ đại the exact same rules and laws of natural selection that were elaborated by Charles Darwin for other biological beings lượt thích plants and animals.

This theory gained popularity in the late 19th and early 20th centuries. This concept enlightens that anthropogenic societies are equivalent vĩ đại organisms that are under constant haul for competition. This continuous struggle vĩ đại prove vĩ đại beat the competition and prosper drives ‘the fittest society’ vĩ đại the peak of evolution.

The weak society eventually gets diminished in size, number and impact. Not just diminished, the weakest societies witness delimitation and regression of their cultural and traditional dimensions, influences, and representation. The stronger and more competitive societies beat the weaker ones vĩ đại rise in power leading vĩ đại overall increased cultural influence in general.

In short, believers and followers of social Darwinism postulated that human lives in an anthropogenic society are always under competition for mere existence. This constant competitive instinct makes one or the other human society the fittest of them all. And this postulate hence justifies the “survival of the fittest” theory in a non-biological sense.

Representatives and propagators of the theory of social Darwinism in England were Herbert Spencer and Walter Bagehot. The representative (and propagator) of the theory of social Darwinism in the United States of America (USA) was William Graham Sumner.

The motto of the theory from a moral perspective is vĩ đại gain tư vấn for capitalism and social and political conservatism. The basis for justification of the motto is the social Darwinists justifying class stratification by saying that these classes are based on natural inequalities among different individuals. They also relate the controlling behavior of the rich class vĩ đại the inherent superior and moral attributes. Some of these attributes are industriousness and frugality.

How the theory of social Darwinism was propagated? Whenever some attempts were made vĩ đại reform human societies via government intervention or moral perspective, the social Darwinists would intrude and intervene claiming it vĩ đại be against the natural processes. They would claim that biological selection is always in favor of unrestricted and cut-throat competition between biological beings. Hence, human societies too, need vĩ đại be in continuous war with each other in order vĩ đại acquire and retain powerful positions in society. Under such a selection theory, the poor are always downgraded vĩ đại the unfit class. Additionally, this theory never even leaves room vĩ đại aid and help the poor vĩ đại get uplifted as it justifies the wiping away of the poor due vĩ đại their less favorable attributes.

Cons of this theory:

  • This theory ONLY served as the justification tool for the increasing gaps between poor and rich in anthropogenic societies.
  • The class differences and the struggle for mere existence were all justified by the blanket cover of social Darwinism.
    Additionally, only “being rich and wealthy” was treated as a sign of success in societies.
    This theory of social Darwinism was heavily exploited as a tool for justifying the ever-increasing imperialism, colonialism, and racism in different domains of society.

Anarchists

The way anarchists viewed the phrase survival of the fittest was again different from social Darwinists. There was one Russian anarchist named Peter Kropotkin who explained the concept of survival of the fittest as a supporting tool (cooperation) and not as a competitive tool.

Peter Kropotkin in his book named “Mutual Aid: A Factor of Evolution” pointed out clearly that the fittest in a group might not always be the best. He emphasized the point that even if an individual is the fittest in some competition, the chances of him being the best are not 100%. He explained that a well-functioning community has vĩ đại be composed of those individually best people who can come together and work their level best as a team.

Eugenics

Eugenics literally stands for eu– meaning good or well and genic meaning “coming into being or growing”. Eugenics is basically a phối of beliefs that target vĩ đại improvise the genetic quality of an anthropogenic population.

Eugenics comes into play when efforts are taken vĩ đại selectively include and exclude certain groups of people based on their attributes. These attributes are defined on the basis of misaligned notions of wealth, some classes and races being superior vĩ đại another.

Eugenics also demotes some races and groups of human populations as inferior vĩ đại others, leaving them with no chances vĩ đại rise vĩ đại positions of power and decision-making in politics.

In the 1820–1914 phases, logic about the survival of the fittest and natural selection became popular. It became a common notion that survival of the fittest is applicable vĩ đại different groups in humanity with the more intelligent people being claimed superior and fitter than vãn the less intelligent ones who were automatically considered less fit and inferior.

It was a British scientist named Francis Galton who first coined the term eugenics meaning the one born with the good genes. He propagated the idea of “over breeding” of the superior, intelligent class. In 1907, this idea was cemented at the Eugenics Education Society of London by Galton. He took forward this idea along with other representatives of the educated class. The aim was vĩ đại actively and voraciously discourage the heavy over breeding of the relatively less fit class. They aimed at preserving the more intelligent and fitter class of Victorian society.
