A federal judge has ruled the University of California can deny course credit to Christian high school graduates who have been taught with textbooks that reject evolution and declare the Bible infallible, the San Francisco Chronicle reported.
U.S. District Judge James Otero of Los Angeles ruled Friday that the school's review committees did not discriminate against Christians because of religious viewpoints when it denied credit to those taught with certain religious textbooks, but instead made a legitimate claim that the texts failed to teach critical thinking and omitted important science and history topics.
Charles Robinson, the university's vice president for legal affairs, told the Chronicle that the ruling "confirms that UC may apply the same admissions standards to all students and to all high schools without regard to their religious affiliations."

In the xylenase example of directed evolution a three amino acid substitution led to an enzyme that worked better at high temperature. This was accomplished by changing the nuclear DNA, thus epigenetic factors are not involved.
==Hsp90...is...about as far as from where epigenetic factors act as is possible to get.
Wrong again, Allmendream:
She points to...a heat shock protein, Hsp90, in Drosophila melanogaster, as “model systems that have very eloquently demonstrated” the critically important role that epigenetic inheritance plays in this kind of gene-by-environment interaction.

Still waiting for that study, Allmendream. I’m citing all my sources, why can’t you do the same???
==This was accomplished by changing the nuclear DNA, thus epigenetic factors are not involve.
Actually, if you read the sources I provided, epigenetic factors have a way of speeding up rates of mutation, as well as releasing hidden variation that was (apparently) already present.
==Yes, and the means that God used to give organisms the ability to adapt to changing environments is through natural selection of genetic variation
Are you dropping RANDOM MUTATION from your vocabulary now?
Sure they can. It's easy to set up an experiment where 2 people have the same set of facts, yet make different decisions.
Except that they don't have the same set of facts. Individual experience is part of the facts that a person has. So are things like emotional state, how tired a person is, whether they have to go to the bathroom, etc., etc., etc.
You can hand them a certain set of facts, ask them a question or to perform a task, and see what the outcome is. However, the facts you hand them are only part of their sets of facts. Everything they have and are experiencing are also facts that you cannot control for.

Top of pageAbstractThe heat-shock protein Hsp90 supports diverse but specific signal transducers and lies at the interface of several developmental pathways. We report here that when Drosophila Hsp90 is mutant or pharmacologically impaired, phenotypic variation affecting nearly any adult structure is produced, with specific variants depending on the genetic background and occurring both in laboratory strains and in wild populations. Multiple, previously silent, genetic determinants produced these variants and, when enriched by selection, they rapidly became independent of the Hsp90 mutation. Therefore, widespread variation affecting morphogenic pathways exists in nature, but is usually silent; Hsp90 buffers this variation, allowing it to accumulate under neutral conditions. When Hsp90 buffering is compromised, for example by temperature, cryptic variants are expressed and selection can lead to the continued expression of these traits, even when Hsp90 function is restored. This provides a plausible mechanism for promoting evolutionary change in otherwise entrenched developmental processes.
Where does epigenetics come in? I notice the source left off the quote marks around the epigenetics part. From your source....
THE THREE MAIN TYPES OF EPIGENETIC INFORMATION
Cytosine DNA methylation is a covalent modification of DNA, in which a methyl group is transferred from S-adenosylmethionine to the C-5 position of cytosine by a family of cytosine (DNA-5)-methyltransferases. DNA methylation occurs almost exclusively at CpG nucleotides and has an important contributing role in the regulation of gene expression and the silencing of repeat elements in the genome.
Genomic imprinting is parent-of-origin-specific allele silencing, or relative silencing of one parental allele compared with the other parental allele. It is maintained, in part, by differentially methylated regions within or near imprinted genes, and it is normally reprogrammed in the germline.
Histone modifications—including acetylation, methylation and phosphorylation—are important in transcriptional regulation and many are stably maintained during cell division, although the mechanism for this epigenetic inheritance is not yet well understood. Proteins that mediate these modifications are often associated within the same complexes as those that regulate DNA methylation.
Genetic variation arises through random mutation. If a gambler looses at dice isn’t it still God’s will that he do so, despite it being demonstrably random?
I'm not in any way surprised that you're familiar with the flavor of both.
They just about have me convinced that they not only came from it, but have not risen above it
Any supposition is a theory - factual or not. Facts, OTOH, are often in the eye of the beholder.
I am fully aware of your life long animus against the Bible, Christianity and attendent beliefs, so you will find your time more profitable flogging your hobby horse with somebody else.
Why do you have such a hard time accepting the evidence that heat stress proteins are related to epigenetics? Does the following make it explicit enough for you?
“Using a sensitized isogenic D. melanogaster strain, iso-KrIf-1, we confirm this finding and present evidence supporting an epigenetic mechanism for Hsp90’s capacitor function, whereby reduced activity of Hsp90 induces a heritably altered chromatin state.”

Now that we know that there is an epigenetic link between the two, let’s move back to the larger discussion, shall we?
PS And I’m still waiting for you to produce the study, or at least an article about the study, you keep referencing. WHAT’S TAKING SO LONG? If it’s such boon to Darwinian evolution, there must be references to the study all over the place.
Why do you wish to attribute your misunderstanding of gravitation to Dan?
Dan said nothing about gravity. Matter and energy are interchangable states of the same thing, and gravitation affects both.
==Genetic variation arises through random mutation.
That’s in part what we’re here to find out.
There you go with your insipid ignorance again!
You haven't a clue what you're talking about; nothing is excluded.
Where did the RNA come from?
(Clue: God provided it so that evolution could not happen, thus protecting his creation from corruption.)
PS The paper you posted is rather antiquated. If you look at the newer studies on the exact same subject, they almost reference the link to epigenetics.
Fixed version:
==This is is a very cool experiment but I’m still not seeing the connection to epigenetics.
PS The paper you posted is rather antiquated. If you look at the newer studies on the exact same subject, they almost (all) reference the link to epigenetics.
God bless you and yours!
He has and is!
On what planet does that make any sense?
