It is often said, it support of evolution, that the marsupials are "more similar" to each other then to their similar looking placental counterpart. This was one of the major lines of evidence that convinced me of evolution. But I would like to dig deeper into this. When scientists say they are more similar, to they refer to bone structure or genetic similarities? Indeed, these must both be true if in reality they evolved from a more recent common ancestor then they share with the placentals; but exactly which lines is more obvious to scientists? Is there a site where the specific evidence is drawn out, perhaps with pictures of the bone structures or descriptions of similar mutations in non-coding dna shared by the marsupials but not the placentals?
Thank you.

Thank you Modulous. This is a good start. I have skimmed over the Bioinformatics thread and it does indeed look like the sort of genetic evidence evolution would suggest, and also, something I might have fun doing! Someday I might see if a laymen like myself can start using this program, it would be fun to make genetic tree of life comparisons of my own.

That looks like a textbook that is probably a wee bit over my head (and over my price range!) but thanks for the reccomendation. I see I can get a 1994 version for $3.00 so I might consider that.

I think the fact that each marsupial is "closer" both genetically and elsewise to eachother then to its counterpart is striking evidence of a common ancestor. However, the fact that it DID happen that they are so similar to a counterpart is still very strange to me.
