Re: [humanism-174] The Descent of Man.

Use of the term "spontaneous generation" fell out of favor in the 19th century as a result of the experiments performed by Louis Pasteur. Prior to Pasteur's experiments it was thought that life spontaneously generated from inanimate objects or from dead, rotting flesh. This idea has roots dating back to Aristotle. The idea of spontaneous generation was displaced by advances in germ theory and cell theory.

The "crystal hypothesis" is pretty cool.

Here is the "RNA World hypothesis" to digest (http://en.wikipedia.org/wiki/RNA_world_hypothesis), and just today there is an article on findings which supposedly challenge the RNA World hypothesis:

Mark,

"Self-organization" seems to be an attempt to form an explanation for the processes underlying the concept of  "spontaneous generation."  "Emergent properties" may (must) result, as must replication, in order to get "life."  These concepts are a start.  A persuasive explanation has yet to be offered.  Graham Cairns-Smith's hypothesis is interesting (http://originoflife.net/crystals/index.html) as are a few others I have read.  We are a long way from an explanation!

Ha! The 3rd comment is golden-
"He forgot #20, in which the hominids beget a god and deny that steps 1-18 ever existed."
Re: Mike- perhaps "spontaneous generation" isn't a good term for it anymore, maybe it should be thought of as patterns of self-organization, emergence and self-replication.

While I will admit to close friends that I am a supernatural/spirituality "Denier," RNA/DNA and the origin of life via spontaneous generation has puzzled me lately.  Some problems are very difficult to solve, I suppose.
