"This seems then to have been the history of life upon this planet:the slow combination of the gasses of the primitive atmosphere to form simple unit organic molecules which then accmulated in the sea; the polymerization of some of those molecules to form the first macromolecules comparable with our present proteins and nucleic acids; the aggregation of such large and small molecules in the sea to form micelles of various sizes and grades of complexity, with te final achievemet of the living state. Then the gradual mastery of the fundamental problems of deriving energy and preparing new organic molecules with which life could eventually spread upon a cosmic scale, in he process transforming radically the atmospere of the planet."

Re the heading "Pre-replicator chemical evolution":  it should be made clear that "evolution" here means evolution in the sense of "change", not evolution in the sense of mutation and natural selection, since the latter process cannot occur without ongoing replication.  --[[User:Catherine Woodgold|Catherine Woodgold]] 17:28, 28 April 2007 (CDT)

Oldest fossils

Just wanted to point out such a chapter is probably necessary. It might eventually go under "Origin of cells". --Nereo Preto 02:04, 5 February 2007 (CST)

Help: My edits caused loss of earlier versions

Help: Could someone restore to last version, by Larry Sanger, as my attempt to add subsection caused loss of earlier version Anthony.Sebastian (Talk) 23:03, 25 February 2007 (CST)

Done, the problem was that you had forgotten to add an </ref> to the end of your text. Chris Day (Talk) 23:12, 25 February 2007 (CST)
Thanks, Chris, for getting me out of trouble, again. Anthony.Sebastian (Talk) 11:11, 26 February 2007 (CST)
