These computations are material, in the sense that they are subject to limitation of resources (nervous signal speeds, chemical equilibrion, diffusion of hormones etc. So the bias toward a low kolmogorov complexity of an habitable universe can be naturally deduced from that.
Natural selection is the mechanism for making discoveries, individual life incorporate these discoveries, called adaptations. A cat that jump to catch a fish has not discovered the laws of newton, Instead, the evolution has found a way to modulate the force exerted by the muscles according with how long the jump must be, and depending on the weight of the cat (that is calibrated by playing at at the early age). But this technique depends on the lineality and continuity of the law of newton for short distances. If the law of newton were more complicated, that would not be possible. So a low complexity of the macroscopical laws permit a low complexity and a low use of resources of the living computers that deal with them, and a faster dsicovery of adaptations by natural selection. But that complexity has a upper limit; Lineality seems to be a requirement for the operation of natural selection in the search for adaptations. http://ilevolucionista.blogspot.com.es/2008/06/ockham-razor-and-genetic-algoritms-life.html Onward! > > Stephen > > -- > You received this message because you are subscribed to the Google Groups > "Everything List" group. > To post to this group, send email to everything-list@googlegroups.com. > To unsubscribe from this group, send email to > everything-list+unsubscr...@googlegroups.com. > For more options, visit this group at > http://groups.google.com/group/everything-list?hl=en. > -- Alberto. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
