Evolution & the 2nd law?

Dear Dr. Sepp,

Do you have references.  I am starting to do some theoretical work in
terms of the information passed through genes and am hoping to use wave
mechanics (I know it sounds far afield) to do some modeling.  Prigogine's
work would probably be quite useful for my edification so if you could
direct me to your source, it would be greatly appreciated.
