Crystal Origins

Organic chemist Alexander Cairns-Smith proposes a radical idea of the origins of life on Earth that points to the potential for life on other planets. Building upon J.D. Bernal’s idea that life’s first molecules came together in clay minerals in the earth, Cairns-Smith theorizes that chemicals in the clay mineral layers “acted as the first genetic information carriers.” The evidence for his claim that DNA formed from inorganic material is found in crystals: Both inorganic crystals and DNA contain self-replicating patterned structures, and both have the ability to reliably copy these patterned sequences. These two qualities form the basis of heredity.
The clay mineral layers that preceded all organic life consisted of layers of crystal structure packed together in an arbitrary sequence, much like the DNA base pairs that make up the complex organisms of the present. Essentially, organic substances evolved from chemical interactions and then stabilized and started to replicate, a process that links inorganic and organic chemistry. If his theory is correct, it’s possible that other planets already contain the mineral template that formed our DNA. Confirmation of Cairns-Smith’s theory could expand the search for extraterrestrial life to planets that were previously thought too hostile for organic organisms.

Interesting Idea
We're living stones?
Clay figurines..
God sleeps in the rock
Nice to see
I love this idea
My own Taoist research cites
Dawkins Does Sacred Geometry?
I love it. The friend from whom I inherited those books was into Dawkins big time, but I don't think he'd be too happy about the Prof's recent attacks on alternative medicines. I used to hang out sometimes at Dawkins' website, but found there that hard-core atheists tend to behave too much like hard-core monotheists: too little tolerance for rival belief systems.
I'm afraid I didn't quite follow about the lobes of the brain and the soy-based silica nano-particles, but I'll give the blog a shot.

Okay, I checked out the blog. That Syrian Rue experience sounds like some serious psychonautical exploration. After an early interest in psychedelics sparked by reading A. Huxley, I've been languishing in fake-reality egoland for thirty years, and am only now trying to find my way out of the desert. Thanks for reminding me of such invaluable navigational tools.

Alternative Theories are Good
We've always been evolved stones...
I wish I could paint with
gemstones. If I could spread a field of minuscule rubies and minutely faceted amethyst grains across a pane of glass or crystal, I'd have the most beautiful fiery sparkling colors that could be imagined. It would last forever too, provided the bonding agent be likewise inorganic and lightfast.
In his essay "Why Are Precious Stones Precious?" Huxley points out that gems not only partake of eternity, but remind us of what he calls "the antipodes of the mind," where scenes of visionary beauty live inside us, which he posits as the answer to his title and question.
