Find the most parsimonious tree

This is a question from Campbell Biology. I demonstrate the procedure for mapping genetic changes onto competing phylogenetic hypotheses by hand.

Thanks to you, I was able to do these types of problems on my exam and was saved from panicking. Thank you!

[mandamania]

would the first tree be the most parsimonious?

[gentianp]

so u not gonna tell which is most parsimonious?

[jamesn.]

why dont you have an outgroup? instead of having to decide which is the ancestral trait.
also, very informative. thank you

It seems that God changes it for you, or, maybe, a "Jesus, for others, " circumstance, possibly like a Virgilian pathway, posssibly (e.g. A personal integral ecology within an intergenerational economy of salvation?). I'm adding this thought to this discussion because I do not believe that God evolves.
