Position Paper (Test) Details:
1) Due Mo14Mar11@3:05pm PDT
2) Handwritten, Typed, or eMail AOK - if eMail, you MUST put your full name, period, and paper title in the subject line of the message, and copy/paste the assignment contents into the body of the message - no attachments.
3) Aim for ~200 words, or 2 sides of a piece of paper handwritten, or one side typed, double spaced, font 12.
4) Suggest 4 paragraphs: Reasons in favor, reasons against, your opinion for or against, referencing the preceeding cited & referenced evidence, and your opinion as to meaning (so what) if your opinion turns out to be validated.
5) Cite all evidence in the for & against paragraphs with footnotes (1) (2) etc., with the specific URL for the cited information (exact page, not just the home page for the site). Attributed quotes are also welcome:>
6) We'll work on this some in class, in dividually checking in with you, as well as sharing out our findings as we assemble our arguments across the week. The sooner you get started, the better the discussion, and the more help I can be - if you have nothing done on your own when I come around to help, I have nothing to work with you on . . .
Mr. Justin's position paper example:
The announcement by Dr. Richard Hoover on finding evidence of cyanobacter and sulfanophagic bacteria inside spinels of CI1 carbonaceous chondrites (1)(1a) blew me away when I first heard about it on CBS News Saturday evening (Sa05Mar11) (2). The only other "Andromeda Strain" (3) / PanSpermia (4) news I remember was also treated with some reserve (5) from NASA AMES AstroBio (6) about 10 years ago. The presented evidence incredible - micro fossils the right size & shape for both cyanobacter and sulfanophagic bacteria, right down to the reproductive cysts & flagella (1)(1a). I was also very impressed by his CV (7) and awards (8) - he's clearly produced world class work.
Considering the case for negation, his only TV news interview was with FOX News (9), and the "peer reviewed journal" he published in looks more like a wing-nut blog (1)(1a), despite the Harvard Astrophys. position of its editor, Dr. Rudy Schild (10). The efflusive testimonials on this singular site fly in the face of the absolute silence from Hoover's own AstroBio lab at NASA-MSFC (11), where he's department chair (?!). Then there's the Lunar & Planetary Science Conference buzz as reported in Science Insider (part of the AAAS journal) (12) , indicating primarily irritated avoidance.
After going over the publication for a couple of hours, I see so much reinforcing evidence that I am most skeptical of intentional falsification, as opposed to error. The author's professional company seem to be almost religiously convicted, and planetary geologists and astrobiologits have been though this before (12). I've seen professional mass avoidance before also, once re: Bill Hartman's Lunar Origin Theory (13), then again across the history of planetology generally; Wegman's continental drift, HTV extremeophile life origins (WHOI-ALVIN), & the 3 Kingdom's I was taught becoming the 5 we all accept knowingly today;>. As I prefer to think of biology emerging in extreme environments, panspermia is where I put my preferences, and stand in the minority supporting the author conditionally - I REALLY want more independent sampling of the CI1 condrites - several more independent researchers will do for me. Until then, I have to constrain my endorsement to conditional.
If my theory is valid, the galaxy is potentially brimming with at least microbial life. That alone implies bountiful opportunities for human colonization, while it also presents an ethics problem of co-opting other biome's independence. Absent indescriminant and widespread replacement land use, I can see huge opportunities to encounter biologically related communities, simplex & hopefully complex, wether technological or not.
