Until now, Alu DNA repeats have been considered "junk dna." The study shows key differences between humans and other primates. The finding is counter to natural selection.

Enjoy!

Science in action Ping.

Than how do you explain liberals?

"Humans march to a faster genetic 'drummer' than primates"

Uh, humans ARE primates. Maybe someone missed the word "other."

[fishtank]

Not to mention the different spiritual component.

Humans are created in the image of God (and I contend that means the spiritual realm, not the physical).

Apes, chimps, etc are not "imago Dei".

A change in research perspective will greatly benefit the progress of science! The delay tactics of the hangers-on, has become a pattern of humorous hand waving.

Multispectral Galaxy Studies Contradict Theories   08/27/2004
The latest issue of Caltech’s magazine Engineering and Science¹ has beautiful pictures of galaxies taken in ultraviolet by the Galaxy Evolution Explorer (GALEX), and in the infrared by Hubble’s sister, the Spitzer Space Telescope.  Combining images of the same galaxy in visible, ultraviolet and infrared is helping astronomers figure out their structure, and as D. Christopher Martin claims, the origin and evolution of galaxies and stars.  Why, then, at the end of the article, does he say this?

The interesting thing is that the history we have measured completely disagrees with some of the most recent models.   (Emphasis added in all quotes.)

He had just pointed out that “our early results seem to be telling us that star formation was much more vigorous in the past” and that “something has changed very radically about star formation since that time....”
    Whatever; discovery marches on.  “We have found many other interesting things, and we have only just begun to survey the sky.  As our own team and other astronomers explore the data, we look forward to many other discoveries in the future.”

"We are not contending that natural selection does not exist....."

How is this finding "counter to natural selection", as you claim?

[Doctor Stochastic]

Other actual quotes from the article:

Here we trace the evolution of AluYb8 repeats from a single origin at the roots of higher primates to a large increase in their number in humans.

In round numbers, 2200 AluYb8 elements came into existence within about five million years of the human lineage.

Counting only non-CpG mutations (CpG dinucleotides mutate abnormally fast33) gave a total of 2682 mutations/537,072 sites, or 4.99 £ 1023/site. Dividing this number by the rate of change in primate introns of 1.5 £ 1029/site per year,34 yields an estimated age of 3.3 million years for this Alu family. This is in fairly good agreement with the estimated five million years of separation of the human and chimpanzee lineages, but it also indicates that the AluYb8 family was dispersing throughout the entire period of the human lineage.

It's good to see the Creationists endorsing an article supporting the common lineage of humans and other primates and that supports the paleobiological time estimates.

The spread of the Alu DNA repeats was written into the chemistry of human chromosomes. The process was not random, Dugaiczyk said, and it was not subject to an environmental "natural selection," separating winners and losers as theorized by Darwin.

I think I saw that episode on the X-Files...

Special creation, anyone?

So what's our excuse?

""We are not contending that natural selection does not exist, but that in this instance it is a chemical process within human chromosomes that explains why humans have an explosive expansion of DNA repeats, and primates do not," Dugaiczyk said"

In other words, human genetics evolves more quickly than other primates naturally. Perhaps even by design?

"So the key to what it means to be human resides in that other 2 percent."

Well, physically perhaps.

"Humans march to a faster genetic 'drummer' than primates, UC Riverside research says"

That would explain why Michael Moore hates the President so much. I never checked, does he have opposable thumbs?

[edsheppa]

"We are not contending that natural selection does not exist, but that in this instance it is a chemical process within human chromosomes that explains why humans have an explosive expansion of DNA repeats, and primates do not," Dugaiczyk said.

An invalid statement, or at least a misleading one. The source of the "chemical process" must be identified and shown to not be a product of natural selection to make the statement valid.

Which only goes to show that scientists are only human and prey to illogic just like everyone else. It's the scientific process that, for the most part, keeps them on the straight and narrow.
