A bone to pick: Missing link is evolutionists' weakest By JEFF FARMER
It has been said that if anyone wants to see something badly enough, they can see anything, in anything. Such was the case recently, but unlike some ghostly visage of the Madonna in a coffee stain, this was a vision of our ancestral past in the form of one recently discovered prehistoric skull, dubbed Sahelanthropus tchadensis.
Papers across the globe heralded the news with great fanfare. With words like "scientists hailed" and "startling find" sprinkled into the news coverage, who couldn't help but think evolutionists had finally found their holy grail of missing links?
For those of us with more than a passing interest in such topics as, "Where did we come from? And how did we get here?," this recent discovery and its subsequent coverage fall far short of its lofty claims. A healthy criticism is in order.
Practically before the fossil's discoverer, the French paleoanthropologist Michel Brunet, could come out of the heat of a Chadian desert, a number of his evolutionary colleagues had questioned his conclusions.
In spite of the obvious national pride, Brigitte Senut of the Natural History of Paris sees Brunet's skull as probably that of an ancient female gorilla and not the head of man's earliest ancestor. While looking at the same evidence, such as the skull's flattened face and shorter canine teeth, she draws a completely different conclusion.
Of course, one might be inclined to ask why such critiques never seem to get the same front-page coverage? It's also important to point out that throughout history, various species, such as cats, have had varying lengths of canine teeth. That does not make them any closer to evolving into another species.
A Washington Post article goes on to describe this latest fossil as having human-like traits, such as tooth enamel thicker than a chimpanzee's. This apparently indicates that it did not dine exclusively on the fruit diet common to apes. But apes don't dine exclusively on fruit; rather, their diet is supplemented with insects, birds, lizards and even the flesh of monkeys. The article attempted to further link this fossil to humans by stating that it probably walked upright. Never mind the fact that no bones were found below the head! For all we know, it could have had the body of a centaur, but that would hardly stop an overzealous scientist (or reporter) from trying to add a little meat to these skimpy bones. Could it not simply be a primate similar to today's Bonobo? For those not keeping track of their primates, Bonobos (sp. Pan paniscus) are chimpanzee-like creatures found only in the rain forests of Zaire. Their frame is slighter than that of a chimpanzee's and their face does not protrude as much. They also walked upright about 5 percent of the time. Sound familiar?
Whether it is tooth enamel, length of canines or the ability to walk upright, none of these factors makes this recent discovery any more our ancestral candidate than it does a modern-day Bonobo.
So why does every new fossil discovery seem to get crammed into some evolutionary scenario? Isn't it possible to simply find new, yet extinct, species? The answer, of course, is yes; but there is great pressure to prove evolution.
That leads us to perhaps the most troubling and perplexing aspect of this latest evolutionary hoopla. While on one hand sighting the evolutionary importance of this latest discovery, a preponderance of these articles leave the notion that somehow missing links are not all that important any more.
According to Harvard anthropologist Dan Lieberman, missing links are pretty much myths. That might be a convenient conclusion for those who have been unable to prove evolution via the fossil record. Unfortunately for them, links are absolutely essential to evolution. It is impossible for anything to evolve into another without a linear progression of these such links.
The prevailing evolutionary view of minute changes, over millions of years, is wholly inadequate for the explanation of such a critical piece of basic locomotion as the ball-and-socket joint. Until such questions can be resolved, superficial similarities between various species are not going to prove anything. No matter how bad someone wants to see it.

The answer was already given to you:
No they did not. The size of the genome was the same before and after the mutations. Further, as I quoted from your study the mutation was helpful only in the particular circumstance the ebg functioned worse in normal situations so as a matter of survivability, it was less prone to survive than before the mutation. This is nothing new. Breeding does the same thing, it makes the genome of the organism less adaptable, less efficient that is why pure-bred animals are less healthy than their wild counterparts.
BTW - this is similar to the case of the nylon bacteria. Nothing new here.
No they have not because a beneficial mutation by duplication is not immediately beneficial. More of your confusionism. Follow the thread, that is why you never quote the statements I made.
You just asked me this five posts ago.
Just post it here so all can see. Enough excuses, enough 'I won the argument elsewhere' nonsense. Just cut and paste it. Have been asking you for it from over a hundred posts back, you are still making excuses. Cut the nonsense, just post it.
Oh yes, you can find polymers all over in nature. Once the plant closes they will die, as I said.
You don't really know what a polymer is, do you?
Vade, can you comment?
Now one might say that if evolution were hung up on a local Maximum, a large genetic change like a recombination or a transposition could bring it to another higher peak. Large adaptive changes are, however, highly improbable. They are orders of magnitude less probable than getting an adaptive change with a single nucleotide substitution, which is itself improbable. No one has shown this to be possible either.

Yes, and keratin (which I also listed separately) is a naturally-occurring (fill in the blank) p***mer. Which is also true of the rest of the things on my list. ;)
I remember the cartoons. I never knew where that came from.
Cellulose.
I noticed that in England they talk about trees being made of plastic. Something I've never heard in American English.
