The branching points of the cladogram may be regarded either as an ancestral species (as in an evolutionary tree) or solely as representing shared characteristics.
Amazing and worth living is finding those little branching points and finding where things get a little bit weird or a little bit different or counterintuitive or surprising, you know, and chasing that.
Microraptor belongs to the clan of dinosaurs that includes Deinonychus, and it's close to the branching point that leads to birds, which means it might represent the body plan of the common ancestor from which both lines evolved.
