"Genetic Sharing Schemes" not phylogenies !

Please USE  the correct OUT-GROUP  for Monodelphis.

"THE CORRECT OUT GROUP is Monodelphis domestica" !

Let's change the NAME ?   Molecular Phylogenies are NOT   true PHYLOGENIES !
They are  "Genetic Sharing Schemes.'    I think it's different !
Monodelphis domestica is sister group for all others.
But M. glirina diverged very few.... "similarities" .......not sister-species....
M. glirina is sister for M. brevicaudata.
Monodelphis domestica is "almost' the ancestor itself.
We'll get there !  I believe ! THE SET THEORY  is the way !
Synapomorphy - my concept is : A universally exclusive character
More comprehensive sets contains less comprehensive sets

Hair SET = Mammals.....Mammary glands SET = Mammals ...........Coincident Sets.

RNA SET = LIFE ..............or such...

OK !   don't worry about !
