DARWIN attributed organic evolution chiefly to the combined action of variation and the struggle for existence, primarily the competitive struggle. This involves certain difficulties. First, the factors named tend to mutual exclusion-the more variation the less struggle. Secondly, were there no ...
Combining these elements, Darwin 30 that the factors of "the struggle for existence"and “thesurvival of the fttest"are the central mechanisms31 which evolutiom is based. In this sense, then, Darwin introducedthe possibility that conflict and 32 are biological phemomena, which are 33 central ...
Darwin described organisms competing for limited resources as a 'struggle for existence'. Differential Fitness Individuals with some phenotypes produce more offspring than others, leading to a shift in the relative numbers of individuals with each genotype in the next generation. ...

In his book, The Origin of Species, Darwin discusses evolution- through variation, why it occurs, the struggle for existence, natural selection, the geological record, and several other topics. This book brought him great recognition as well as many violent attacks. It was written in a time ...
shd.be forestalled. You said this when I explained to you here very briefly my views of “Natural Selection” depending on the Struggle for existence.— I never saw a more striking coincidence. if Wallace had my M.S. sketch written out in 1842 he could not have made a better short ...

In 1880, “Darwin’s Bulldog” Thomas Henry Huxley wrote, “The struggle for existence holds as much in the intellectual as in the physical world. A theory is a species of thinking, and its right to exist is coextensive with its power of resisting extinction by its rivals.” Knowl...

If it is species that are competing in what Darwin called the struggle for existence, the individual seems best regarded as a pawn in the game, to be sacrificed when the greater interest of the species as a whole requires it. To put it in a slightly more respectable way, a group, such...
