Blind, Undirected (chemical) Processes

-
The evotardgasms are reaching monumental proportions.

First I was told I was wrong by saying evolution is an accumulation of genetic accidents.

So I provided the references that support what I said and the evotards just seem to quiet down for a while. But they never acknowledge their mistake.

Oh well.

Now it appears those evotards are back into evotardgasm form when I mention "blind, undirected chemical processes" as being the proposed mechanism of evolution.

So here is the evolutionary references to support my claim:

Eric B Knox, "The use of hierarchies as organizational models
in systematics", Biological Journal of the Linnean Society (1998), 63: 1–49:
Evolution is rife with examples of such apparent conflict because it is an inherently dualistic process. This dualism is obvious in Darwin’s enduring characterization of evolution as descent with modification. This dualism is manifested in a mechanism that is prospectively blind, but retrospectively capable of organic improvement. page 4 (bold added)


Then we have:
“Natural selection is the blind watchmaker, blind because it does not see ahead, does not plan consequences, has no purpose in view.” Dawkins in “The Blind Watchmaker”


and:

“Natural selection is the simple result of variation, differential reproduction, and heredity—it is mindless and mechanistic.” UCBerkley


From the “Contemporary Discourse in the Field Of Biology” series I read- Biological Evolution: An Anthology of Current Thought, (edited by Katy Human). This is part of a reviewed series expressing the current scientific consensus.

Uncertainty, randomness, nonlinearity, and lack of hierarchy seem to rule existence, at least where evolution is concerned.- page10


The old, discredited equation of evolution with progress has been largely superseded by the almost whimsical notion that evolution requires mistakes to bring about specieswide adaptation. Natural selection requires variation, and variation requires mutations- those accidental deletions or additions of material deep within the DNA of our cells. In an increasingly slick, fast-paced, automated, impersonal world, one in which we are constantly being reminded of the narrow margin for error, it is refreshing to be reminded that mistakes are a powerful and necessary creative force. A few important but subtle “mistakes,” in evolutionary terms, may save the human race. -page 10 ending the intro


What Causes Mutations?:
Mutations in DNA sequences generally occur through one of two processes:
1. DNA damage from environmental agents such as ultraviolet light (sunshine), nuclear radiation or certain chemicals


2. Mistakes that occur when a cell copies its DNA in preparation for cell division.

Causes of Mutations:
1. DNA fails to copy accurately
Most of the mutations that we think matter to evolution are "naturally-occurring." For example, when a cell divides, it makes a copy of its DNA — and sometimes the copy is not quite perfect. That small difference from the original DNA sequence is a mutation.


2. External influences can create mutations
Mutations can also be caused by exposure to specific chemicals or radiation. These agents cause the DNA to break down. This is not necessarily unnatural — even in the most isolated and pristine environments, DNA breaks down. Nevertheless, when the cell repairs the DNA, it might not do a perfect job of the repair. So the cell would end up with DNA slightly different than the original DNA and hence, a mutation.


DNA Replication and Causes of Mutation:
DNA replication is a truly amazing biological phenomenon. Consider the countless number of times that your cells divide to make you who you are—not just during development, but even now, as a fully mature adult. Then consider that every time a human cell divides and its DNA replicates, it has to copy and transmit the exact same sequence of 3 billion nucleotides to its daughter cells. Finally, consider the fact that in life (literally), nothing is perfect. While most DNA replicates with fairly high fidelity, mistakes do happen, with polymerase enzymes sometimes inserting the wrong nucleotide or too many or too few nucleotides into a sequence. Fortunately, most of these mistakes are fixed through various DNA repair processes. Repair enzymes recognize structural imperfections between improperly paired nucleotides, cutting out the wrong ones and putting the right ones in their place. But some replication errors make it past these mechanisms, thus becoming permanent mutations. These altered nucleotide sequences can then be passed down from one cellular generation to the next, and if they occur in cells that give rise to gametes, they can even be transmitted to subsequent organismal generations. Moreover, when the genes for the DNA repair enzymes themselves become mutated, mistakes begin accumulating at a much higher rate. In eukaryotes, such mutations can lead to cancer. (bold added)


And finally:

The Elie Wiesel Foundation for Humanity- Nobel Laureates Iinitiative

September 9, 2005
Logically derived from confirmable evidence, evolution is understood to be the result of an unguided, unplanned process of random variation and natural selection.


IOW once again it appears that some/ most of the inernet poseurs don't even understand their own position.

And that is beyond pathetic...

    I follow your discussions on C.Hunters blog.I understand your point more completely after reading this blog. This is one of the tughest questions you could ask evolutionist. No wonder they are avoiding direct answer. You could pick on their weak logic.

    You and some others can keep up with followers of evo religion.
    I mostly read and only sometimes post-that's because I'm technical person just interested in biology.

    Thanks Eugen-

    I am also interested in biology.

    That is why I hate what evos are trying to do with it.

    Biology- OK- leave the fantasizing about the past for some other class.

    Evolution is not undirected at all. The goal of all selection is adaptation to a niche in the ecosystem. It is the ecosystem that makes the selection and forces the organisms to adapt to a niche which they have to do in order to survive. The direction comes thus from teh ecosystem.

    Nice try. Unfortunately for you you don't have a reference to support what you post. OTOH I have supported what I posted.

    Also natural selection is eliminative, meaning there isn't any selecting going on.

    Natural selection doesn't do anything beyond eliminating the less fit and deficient. Adaptation, if it happens, occurs by accident.
