[Bioperl-l] phylogenetic question

[Pedro Antonio Reche]

Hi all,
I have a couple of questions and I thought some of you may know the  
answers. Here we bo. Given a set of related proteins is there a way to  
tell ancestry in absolute terms?. Also,  given a couple of paralogs, is  
it possible to know which one is the ancestor. Any help, indication,  
etc is very welcomed.
Cheers
