If you have time you can read the link provided above.But you might need to know about the different computational phylogeny methods to understand the paper.
Anyways do you think such a "relationship" is possible.Or do you think it might be a flaw in the method of alignment used or the different methods used to get the phylogenetic tree.
Or do you think such relationship is possible.
I have also encountered with a similar problem.Thats why i wanted to get some suggestions.......
I have also posted the same topic in Evolution forum to get a wider spectrum of answers.
