DESCRIPTION:Grand laws in biology are elusive. We know convergent evolutio
 n happens\, but how much of it is down to chance\, and how much of it is d
 own to yet-undiscovered general principles of how organisms evolve\, is un
 clear. \nOne example of potentially convergent evolution\, is constraints 
 on the the four-letter coding of DNA. We have discovered some interesting 
 patterns in DNA of all living organisms. They appear to have a biological 
 basis\, but one heavily determined by limited combinatorial possibilities.
  Anyone who thinks they can interpret mathematical patterns in DNA is very
  welcome to come along and tell us what they think is going on.
