X-chromosome Revealed

As a cheap tabloid might headline it, "X-chromosome Revealed," the University of California Berkley has done a study of the X-chromosome in a piece titled, The Story Of X: Evolution Of A Sex Chromosome. Scientist Doris Bachtrog says, "Contrary to the traditional view of being a passive player, the X chromosome has a very active role in the evolutionary process of sex chromosome differentiation."

"In our manuscript, we demonstrate for the first time the flip side of the sex chromosome evolution puzzle: The X chromosome undergoes periods of intense adaptation in the evolutionary process of creating new sections of the genome that govern sexual differentiation in many species, including our own," she said.

Wow. Imagine that. So I'm guessing that the Genesis story is, well, just a tale fabricated by people who hadn't a clue. "But for Adam no suitable helper was found. So the LORD God caused the man to fall into a deep sleep; and while he was sleeping, he took one of the man's ribs and closed up the place with flesh. Then the LORD God made a woman from the rib he had taken out of the man, and he brought her to the man."

Cute story. I wonder if Dr. Bachtrog and her associates at the integrative biology lab ever discuss that official version of the X-chromosome. Probably not.

Then there is that other possibility concerning that rib transplant- the one about adult stem cells and all.  Perhaps the LORD God was actually part of an advanced civilization that cooked up 'woman' from Adam's stem cells.

Lest we forget, there is that other creation story in the bible as well, the one about the mud and the nostrils.    Could this mud-stuff have referred to the primordial soup of eons ago from which the first animal arose?  Who knows?  Maybe humans were 'seeds' spread throughout space by another advanced civilization and our 'seed' took here on earth, in the muddy swamps.

Perhaps we are a Sci-Fi experiment....gone mad!
