Once again, Darwin did not coin the term "survival of the fittest." He did use it, however, in later publications. Herbert Spencer is credited with composing the term. And Darwin later utilized the term. P.S. It's important as far as I am concerned to have accurate information. Thus, Darwin did not coin the term "survival of the fittest," but used it in later writings.
i have mentioned that many times before, in past threads. We know that Darwin have used later this term, but “survival of the fittest“ isn’t an evolutionary mechanism. So that’s old news.
The problem is you and lot of creationists like you, misrepresent and misuse “survival of the fittest”, because you don’t understand that the phrase only describe what it like, but it isn’t the actual mechanism of evolutionary biodiversity.
The ACTUAL MECHANISM (one of five mechanisms) is Natural Selection, and the “driving forces” behind genetic variations are biodiversity and speciation are ENVIRONMENTAL CHANGES, not “survival of the fittest”.
When the environment changed (eg climate changes like glaciation or aridity that can decrease food resources or water availability, or geographic isolation, etc), those with traits that are more adapted to the environment, the population growth are more likely to increase, than those with traits less adapted to the environments.
What “fittest” really means is adaptability, and what “survival” really means, is about reproduction, population increases/growth vs decreases/declines.
I will iterate again, Darwin’s framework is “Natural Selection”, not “survival of the fittest”.
The phrase (survival of the fittest) is merely descriptive, not explanatory, meaning it uses is more like adjective, like saying the sky is blue, is a description of colour, offering no explanation as to how the sky is that colour. If you really want explanation as to how sky looks blue, is because radiation hit the gases in the atmosphere, which are mostly nitrogen, meaning the blue wavelengths scattered more than other wavelengths (eg red, yellow, green). You need to understand how electromagnetic radiations of sunlight interact with certain atoms (gases).
Describing the sky is blue, isn’t explanation, just as using “survival of the fittest” to describe Natural Selection, isn’t explanation. You don’t understand that, and neither does
@cladking.
cladking frequently use “survival of the fittest”, and not Natural Selection, just demonstrates cladking’s incompetency in understanding biological principles.
