Genetic discovery marches on and, as I predicted, is changing the earlier concepts of Darwinian evolution. There is now evidence that a simple tree of life does not exist and Simon Conway Morris' theory of multiple attempts at various organs (especially the eye) is on the mark. Below is a summary of a genetic approach to the 'tree': http://nar.oxfordjournals.org/cgi/content/abstract/gkp089v1 - 
David, - Is Darwin's evolution concept of the simple tree of life that all genes come from one beginning? Is the above findings saying genes come from many beginnings? I read the summary but could not understand what their findings have found. Could you explain in layman terms? - Thanks
