Understanding Natural Selection: Essential Concepts and Common Misconceptions - Evolution: Education and Outreach
I couldn't find the quote about "Every living organism wants to survive and be in existence." No idea where it was mined from. It doesn't seem to appear anywhere in the paper, so there is no context available to associate with it. Not an unusual feature of the style of presentation seen from the non-science position.
What it does say flies in the face of previous claims regarding intent, randomness, natural selection. In light of those claims it is strange to see it brought to bear as evidence of the veracity of those claims.
The title itself implies the state of natural selection as an accepted scientific concept and this is defined as the mechanism of evolution. Understandably, no mention of intent.
Here is the opening line that defines the environment as the source of the selection.
"Natural selection is a non-random difference in reproductive output among replicating entities, often due indirectly to differences in survival in a particular environment, leading to an increase in the proportion of beneficial, heritable characteristics within a population from one generation to the next."
Note mention of selection as a non-random element. Recall that consideration of randomness was heaved at us as a bug bear that had no standing in the discussion. Seems that was wrong. Who woulda guessed it?
It goes on to reiterate the role of natural selection in evolution with no mention of intent.
"It is one of the core mechanisms of evolutionary change and is the main process responsible for the complexity and adaptive intricacy of the living world."
I was particularly struck at how the article opines how poorly understood the theory is. As an example, we have seen such misunderstanding promoted on this thread as some sort of 'truth'. It is a pleasure to see this introduced to the thread by someone with a metaphorically shot up foot. I find, the self-refuting to be very cooperative in making my point for me.
It is a very good little review paper and worth reading, but I'll wind this down here with one final excerpt from the text regarding the issue of randomness again and how it is actually treated. There will be no mention that the survival of living things is random. Though previously cited as a claim of science, this is not so and the paper clearly highlights the erroneous not nature of that claim while pointing out how randomness is understood to be involved in the process.
"In particular, mutations are known to be random (or less confusingly, “undirected”) with respect to any effects that they may have. Any given mutation is merely a chance error in the genetic system, and as such, its likelihood of occurrence is not influenced by whether it will turn out to be detrimental, beneficial, or (most commonly) neutral."
This portion of the paper was discussing variation and the source of variation in mutation. Mutation is the random feature of evolution while, selection is the non-random component involving the interaction of that random variation with the action of the environment upon it. There is no evidence of any intent in the process.
While instinct drives the general effort to survive, it is not a mechanism that drives one phenotype to greater success over another. Merely following that instinct or, for those that can, wanting to survive is not a guarantee of survival or that in surviving, that particular genotype proliferates through the population by default. Over time, under natural conditions, the less fit genotypes will fall out of the population regardless of the instinct of the organisms that possess it. Not to wave a hand at the value and place of the survival instinct, but to point out that it is not a demonstration of intent and is not part of the mechanism of evolution. Populations in stasis also have a survival instinct.
