My messages to the everything-list http://groups.google.com/group/everything-list/t/79a721c063a6c37a 28.01.2012 13:04: Let my quote Jeffrey Gray (Consciousness: Creeping up on the Hard Problem, p. 33) on biology and physics. “In very general terms, biology makes use of two types of concept: physicochemical laws and feedback mechanisms. The latter include both the feedback operative in natural selection, in which [...]

Jason Resch on the everything list maked a link to a nice video 20.01.2012 02:34 Jason Resch: “Some have argued that cars are alive. They evolve, consume, move, reproduce and so on. While they are dependent on humans for reproduction, we too depend on a a very specific environment to reproduce. Much like viruses.” Lee Cronin: [...]

Some time ago sergei_sh has brought to my attention the works of Jeffrey A. Gray and I have decided to read his book, Consciousness: Creeping up on the Hard Problem. I will definitely write more about it, as I like it a lot. Right now one statement not that related to the main content of the [...]

http://groups.google.com/group/everything-list/t/37514d7224e09703 Discussion that I have started on the everything-list. Below some answers from Bruno. Embryogenesis fits very well. The second recursion theorem of Kleene provides the conceptual solution of a problem given by Descartes: how to build a machine capable of self-reproduction. I have explained the ‘trick’ sometimes. I use a generalisation by John Case [...]
http://www.ted.com/index.php/talks/bonnie_bassler_on_how_bacteria_communicate.html Quite an interesting talk. Some quotes: There is about a trillion human cells that make each one of us who we are and able to do all the things that we do, but you have 10 trillion bacterial cells in you or on you at any moment in your life. So, 10 times more [...]

NEWMAN http://dx.doi.org/10.1016/0022-5193(70)90078-0 A short paper that states: A view is presented which argues that hierarchically organized, complex systems are in no sense unlikely to come about in a world in which thermodynamics is operative, and that they, in fact, often represent states of [...]
Epigenetic learning in non-neural organisms SIMONA GINSBURG, and EVA JABLONKA J. Biosci. 33(4), October 2008 http://www.ias.ac.in/jbiosci/gins68.pdf A pretty interesting paper. A good starting point is the definition of Epigenetics. Definition of learning in the paper: We therefore say that simple forms of learning occurred when: (i) One or more inputs (e.g. external sensory stimuli or [...]
