Re: [meteorite-list] Texas State Research Sheds New Light on Panspermia
Hi, All, survivors he found--a bacteria called Microbispora. Ironically, Microbispora wasn't one of the three species McLean expected to find... McLean determined that it had contaminated the experiment prior to launch... There's a beautiful demonstration of the way Life, the Universe, and Everything (equals 42) works! The shuttle was intelligently designed. The experiment was intelligently designed (to make a pun on that silly notion). Everything was carefully planned. What happened? An Opportunist was the winner, some little bug too dumb to die. Microbispora didn't plan to take a trip to outer space and return to the Earth, but in the end he fared better than the much more capable lifeform that accompanied him. To those who say Evolution can't work (or Life can't arise) through the workings of chance, take a look at Microbispora's vacation trip. So, they're sitting in a Texas parking lot, and one Microbispora turns to the Microbispora next to him, and says, Well, that wasn't so bad, was it? I dunno. We were awfully lucky. Life favors the Opportunist (Exhibit One: Bill Gates) Loren Eisley wrote a fine essay on the primordial fish who, when his pond or puddle dries up, stakes everything on a wild leap in the hope of landing in a better pond or puddle. Many die. Enough land in or near a new pond or puddle and survive that the impulse to make that hopeless suicidal (for a fish) leap is inherited. Those suicidal fish who struggle hardest to find new water, clawing at the mud with their fins to crawl, are most likely to survive. This favors strong footy fins. Before you know it, some of their children just get up and RUN to the nearest pond in a gill-searing dash to find breathable water. Well, you can see where this is going. Eventually, fish are getting out of the water to eat plants and hunt insects and dance by the light of the moon, no doubt to the dismay of their ancestors. Why, you could hardly call some of them fish anymore! All because of an Opportunist who was willing to gamble, senselessly, against the odds. I hope McLean takes these Opportunists back to the lab and gives them a good home. Make a little sign for their petrie dish that says, Bacterial Astronaut Retirement Home. Sterling K.

With the Icarus publication, McLean anticipates request for samples of this rugged strain to come in from researchers around the world. This organism appears to have survived an atmospheric passage, with the heat and the force of impact, he said. That's only about a fifth of the speed that something on a real meteorite would have to survive, but it is at least five or six times faster than what's been tested before. This is important for panspermia, because if something survives space travel, it eventually has to get down to the Earth and survive

Howdy Was it luck, though? Exhibit A from the article: Microbispora wasn't one of the three species McLean expected to find. The slow-growing organism is normally found in the soil, and McLean Note that this is a common soil microbe. The fragment landed on the ground. That's where these guys live. Let me offer an alternative conversation for our hardy microbes: (Scene opens. Two microbes are lying comfortably in a dirty, wet parking lot. Large fragment of spacecraft enters stage left, splatters itself with goo, including the microbes.) Microbe 1 (to Microbe 2): What the @[EMAIL PROTECTED] was that?!! Microbe 2: Dunno, but it shore is tasty! Look at all this mud! Cheers, MDF Hi, All, survivors he found--a bacteria called Microbispora.

This doesn't prove anything--it just contributes evidence to the plausibility of panspermia. Realistically, that's all it can do, McLean said. Out of respect for the seven people who gave their lives for this research, I feel it's very important these results don't get lost. __ Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
