By and large, most aspects of Evolution taught in schools are indeed observable fact. Evolution does happen in the genome.
Scientifically Evolution is the best explanation that can be scientifically promoted. Theories of Creation that say god did it lack one scientifically sound aspect. You cannot scientifically demonstrate that a God is the cause.
The argument lies in whether the observable aspects of evolution are enough to allow for common descent. Most recent arguments are that there is no known barriers to prevent it.
What hinders more honesty in this area of science is because of CHRISTIANS. They want to remove everything associated with the term evolution. They want to say that since evolution can be shown to have problems that automatically means God did it. That is BAD science.
Hi Phazel,
First off I want to say I do not believe the Christian 6 literal days hypothesis, but if evolution is one thing it is the fact that science cannot even reproduce one single aspect of it! Science only throws an "abra cadabra" and billions of years at the life process and there you have it.
Micro evolution is one one thing but an entire new species? Even a wing or how about the eye? The fossil record shows them appearing all at once, fully formed and functional.
Do you have any examples of these observable facts of evolution being presented in the classroom? The only observable mutations on record are degenerative, birth defects and the like, I am unaware of any advantageous birth "mutations" being observed but perhaps I have missed them. From Gerald Schroeder*
With the advent of molecular biology's ability to discern the structure of proteins and genes, statistical comparison of the similarity of these structures among animals has become possible. The gene that controls the development of the eye is the same in all mammals. That is not surprising. The fossil record implies a common branch for all mammals. But what is surprising, even astounding, is the similarity of the mammal gene the gene that controls the development of eyes in mollusks and the visual systems in worms. The same can be said for the gene that controls the expression of limbs in insects and in humans. In fact so similar is this gene, that pieces of the mammalian gene, when spliced into a fruit fly cell, will cause a fruit fly eye to appear at the site of the 'splice' . This would make sense if life's development were described as a tree. But the bush of life means that just above the level of one-celled life, insects and mammals and worms and mollusks separated.
The eye gene has 130 sites. That means there are 20 to the power of 130 possible combinations of amino acids along those 130 sites. Somehow nature has selected the same combination of amino acids for all visual systems in all animals. That fidelity could not have happened by chance. It must have been pre-programmed in lower forms of life. But those lower forms of life, one-celled, did not have eyes. These data have confounded the classic theory of random, independent evolution producing these convergent structures. So totally unsuspected by classical theories of evolution is this similarity that the most prestigious peer-reviewed scientific journal in the Untied States, Science, reported: "The hypothesis that the eye of the cephalopod [mollusk] has evolved by convergence with vertebrate [human] eye is challenged by our recent findings of the Pax-6 [gene] ... The concept that the eyes of invertebrates have evolved completely independently from the vertebrate eye has to be reexamined."
The significance of this statement must not be lost. We are being asked to reexamine the idea that evolution is a free agent. The convergence, the similarity of these genes, is so great that it could not, it did not, happen by chance random reactions.
The British Natural History Museum in London has an entire wing devoted to the evolution of species. And what evolution do they demonstrate? Pink daisies evolving into blue daisies; small dogs evolving into big dogs; a few species of cichlid fish evolving in a mere few thousand years into a dozen species of cichlid fish. Very impressive. Until you realize that the daisies remained daisies, the dogs remained dogs and the cichlid fish remained cichlid. It is called micro-evolution. This magnificent museum, with all its resources, could not produce a single example of one phylum evolving into another. It is the mechanisms of macro-evolution, the change of one phylum or class of animal into another that has been called into question by these data.
The reality of this explosion of life was discovered long before it was revealed. In 1909, Charles D. Walcott, while searching for fossils in the Canadian Rocky Mountains, came upon a strata of shale near the Burgess Pass, rich in that for which he had been seeking., fossils from the era known as the Cambrian. Over the following four years Walcott collected between 60,000 and 80,000 fossils from the Burgess Shale. These fossils contained representatives from every phylum except one of the phyla that exist today. Walcott recorded his findings meticulously in his notebooks. No new phyla ever evolved after the Cambrian explosion. These fossils could have changed the entire concept of evolution from a tree of life to a bush of life. And they did, but not in 1909. Walcott knew he had discovered something very important. That is why he collected the vast number of samples. But he could not believe that evolution could have occurred in such a burst of life forms, "simultaneously" to use the words of Scientific American. This was totally against the theory of Darwin in which he and his colleagues were steeped. And so Walcott reburied the fossils, all 60,000 of them, this time in the drawers of his laboratory. Walcott was the director of the Smithsonian Institute in Washington D.C. It was not until 1985 that they were rediscovered (in the draws of the Smithsonian). Had Walcott wanted, he could have hired a phalanx of graduate students to work on the fossils. But he chose not to rock the boat of evolution. Today fossil representatives of the Cambrian era have been found in China, Africa, the British Isles, Sweden, Greenland. The explosion was worldwide. But before it became proper to discuss the extraordinary nature of the explosion, the data were simply not reported. It is a classic example of cognitive dissonance, but an example for which we have all paid a severe price.
