Origin of Life: comets? (Introduction)
by David Turell 
, Monday, September 16, 2013, 15:02 (3869 days ago) @ David Turell
A lab experiment found that comets smashing into an icy planet can produce amino acids. Apparently found one essential amino acid in the mix: but, of course, equally both right and left handed. Why does life choose to be lefty?-http://www.nature.com/ngeo/journal/vaop/ncurrent/full/ngeo1930.html-Meteorites bring more useful amino acids, eight. Keep trying, guys, but the origin of life stil looks miraculous to quote Paul Davies.
