What is the difference between shared ancestral characteristics and shared derived characteristics in terms of sorting organisms on a phylogenetic tree?
1) A shared ancestral character describes a characteristic that only a certain clade of organisms share while a shared derived character describes characteristics that all organisms on the tree share
2) A shared ancestral character describes a characteristic that all organisms on the tree share while a shared derived character describes characteristics that only a certain clade of organisms share
3) A shared ancestral character describes a characteristic that all organisms on the tree share while a shared derived character describes characteristics that are analogous between organisms
4) Nothing, they describe the same thing
