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”. How This ‘Survival of the Fittest’ Phrase Came Into ExistenceĬharles Darwin drafted and published his writing called “Principles of Biology” in 1864. Figure 2: A cartoon showing what fitness means from a biological perspective. The survival of the fittest in the virus world depends on those trans-generationally inheritable attributes that endow a virus with the ability to produce more viruses (higher viral load) with more virulence than the parental generation virus. To make it further clearer for you to understand, let’s take the example of viruses.

When we talk in a more scientifically aligned manner, “reproductively fit” means those inheritable characters that empower a species to amp up and boost its chances of producing “the fittest” generation, year after year, decades after decades, era after era, and so on… And even the effect of this selection of the fittest is reflected at the species level. In contrast to the fit individuals or species, unfit individuals or species don’t pass the test of producing enough copies of their own.Įven though we tend to commonly use this phrase up to the individual level, such evolutionary processes usually play out their roles that are ‘observable and significant’ at the species level. When we are asked to explain natural selection and survival of the fittest in the subject of Biology, we take forward the concept of biological or reproductive fitness. Interpreted as Expressing a Biological Theory Such fitness, in all its totality, takes care of the “species continuation” BUT with “the best gene pool”. Leaving more progenies ensures that the maximum copies of an organism continue to inhabit the Earth even when that parent individual organism ceases to exist (after its death). When evolutionary biologists use this term, they tend to convey the meaning that a biologically fit organism is expected to leave as many (maximum) progenies as possible. 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.
