A new approach in the lab. Trying a nucleotide with a simpler sugar. Note the reference to Darwinian evolution of a molecule. Evolution opccurs ijn life, not pre-life. Also note the use of a polymerizing enjyme, just hanging around in the pre-life era? I love active grantsmanship in the OOL labs!

Another note about this odd molecule. Note the comment about the messiness of the old Earth and probably this molecule dod not exist.:

Some of the latest thinking. Too much potassium in sea water for life to start:-http://www.newscientist.com/article/dn21471-russian-hot-springs-point-to-rocky-origins-for-life.html?page=2

Now a breathless report that DNA started life. Please note the ifs, ands, and buts:-http://www.newscientist.com/article/mg21528795.500-dna-could-have-existed-long-before-life-itself.html-Pie in the sky reporting. Note the comments, especially the sharply negative.

More wishful thinking aabout OOL. Simple sugar in space means life is ready to start. Foolishness:-http://www.sciencedaily.com/releases/2012/08/120829064835.htm

The research goes on: packing RNA into containing material induces some reactivity. In real time 3.6 billion years ago how did RNA appear and how did it get packed into other chemicals? And where did they come from on an inorganic chemistry Earth? Just-so chemistry to justify a grant.-http://www.sciencedaily.com/releases/2012/10/121014162906.htm-Second version:-http://phys.org/news/2012-10-early-earth-cells-life-packaged-rna.html
Origin of life; RNA cooperation

More wishful thinking in the lab. Intelligently mix up pieces of RNA and they can reassemble: -http://phys.org/news/2012-10-rna-ribozymes-cooperate-reassemble.html-How many convenient petri dishes were on ancient Earth? And how did ribozymes appear in the first place?
