	Well, I will try to explain it clearly in english (quite 
hard for me ;-). There is no ancient gene in living organism and
there is no living organism that is the most ancient. If you
want to find an old gene and an old organism, you have to make
some paleontology. Extant living organism has evolved as long
as you and me, they diverge earlier in evolution (this perhaps
has to be said differently)>
	A living organism, in all phylum, did receive the same
amount of mutations and so the genes in their are also
divergent from the common ancester.

	If one of the good-english-speaking-thinking-like-me guru
can explain it better, I would ne gratefull...
