   >>>>>> to be searched. Those thousands of new genes evolved after a basic   
   >>>>>> set of genes had already evolved, and they evolved over a billion   
   >>>>>> year period before the Cambrian explosion.  The initial gene set

   >>>>>> The likely reason that nearly all new genes have evolved from   
   >>>>>> existing genes is that just a random sequence of amino acids will   
   >>>>>> fold up and could have some function, but most random sequences do   
   >>>>>> not efficiently produce the same structure.  It can take time to   
   >>>>>> fold up, and the sequence might not fold up into the same
