An analysis of the science in the lake washington in 1937 science has proven that evolution is the key to our adaptation patterns over millions of years humans , birds, reptiles, and fish have evolved to survive in their environments this can be found in the simplest life forms as well as the most complicated life forms.
A equals a similarly, herbert spencer's phrase, “survival of the fittest,” used frequently as a short definition of natural selection by darwin (in later editions of the origin) and many others since, is a tautology and circular because “survival” and “fittest” reduce to the same concept what survives the fittest.

The analysis demonstrates through textual examination that the relationship between the expressions 'natural selection' and 'survival of the fittest' was not, as is often assumed, one of equivalence, but that it embodied intellectually significant modifications of darwin's position not acknowledged within references ,. The former concerns the survival of the fittest the latter, however, is an aspect of evolution that is too often overlooked today after writing on the origin of species, darwin was perplexed by the marvellous phenomena that natural selection could not easily explain the peacock's tail, he wrote in a letter to.

Excerpts from darwin's 'on the origin of species' describing 'natural selection' and 'survival of the fittest' as terms which denote that some animals survive to breed and some don't animals with a slight advantage have a better chance of survival footage shows a gazelle that is fast and strong enough to evade a cheetah.

A species is a population of organisms that interbreeds and has fertile offspring • living organisms have descended with modifications from species that lived before them • natural selection explains how this evolution has happened: — more organisms are produced than can survive because of limited resources. In the case of natural selection, traits that increase the likelihood of survival and reproduction will become more common within a population or species over time in the past, natural selection has been misrepresented by calling it the survival of the fittest this statement oversimplifies the mechanism by.
The biological concept of fitness is critical to an understanding of natural selection and of evolution in general while philosophers continue to argue about the best way to define fitness, there are some generally accepted aspects of biological definitions of fitness first, it is a term applied to an allele or. When charles darwin was first coming up with the beginnings of the theory of evolution, he had to look for a mechanism that drove evolution many other scientists, such as jean-baptiste lamarck, had already described the change in species over time, but they did not offer an explanation as to how that. 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.
