Does this discussion of traits, and a possible bird-dinosaur nexus,
have any meaning if we're analogizing to common traits in such such
broad groups as entire phyla?

Some dinosaurs, our phylum mates but not much else, were bipedal. 
Does that help us at all in determining the geneology of also-bipedal
Homo sapiens sapiens? Are we "secondarily bipedal" for that reason?
