Getting around the 2nd Law
Evolution of species is not in conflict with the second law. The second law applies to a closed system, such as, e.g. the universe as a whole. It is in a predermined decay and has been so ever since the silent Big Bang. Life on Earth is not a closed system - we constantly receive very low entropy energy input from the sun which allows local entropy reduction whereas the system as a whole grows its entropy.

Re: Getting around the 2nd Law
I have looked at message 26. It does not contradict my original message in any way. I state clearly that a local reduction in entropy occurs at the cost of a total increase of entropy in the system.

Re: Getting around the 2nd Law
The statement concerning the 2nd law applying to a closed system must be seen in the light of the original message to which I answered. My response implied that a closed system cannot lower its entropy.
