Microraptor and Birds
How are Aves and Avialae currently defined? Is either clade closer to
synonymy with the colloquial term, "bird"?
Now, on to _diagnosis_. What synapomorphies -- if any -- banish
_Microraptor gui_ from inclusion into either clade, and -- in light of
the unfortunate circumstance that no one has had the privilege of
personally seeing all relevant life forms evolving and radiating over
millions of years -- how has this set of distinguishing synapomorphies
been determined? Do different taxonomists use different sets of
synapomorphies to determine membership for these clades?
