Linking the origin of birds to dinosaurs

Excerpt: “It is definitely an example showing how much experimentation occurred,” said palaeontologist Xu Xing of the Chinese Academy of Sciences in Beijing, who co-authored a study in the journal Nature.
“Close to the origin of birds (from dinosaurs)… many lineages tried in a different way to get into the air, but finally only one group succeeded.”
My comment:  This example of what is placed into the context of evolutionary experimentation could be linked to re-evolution of the bacterial flagellum “over-the-weekend.” Also, when compared to bacteria that appear to have not changed in ~2 billion years, weird-winged dinos may help theorists establish biologically-based facts about how long it takes for one species to evolve into a different species. Theorists might begin to include experimental evidence that attests to facts about the conserved molecular mechanisms of nutrient-dependent pheromone-controlled RNA-mediated cell type differentiation in species from microbes to man.
For example, in theory, the time it takes for all biomass to evolve appears to range from 4.5 billion years to 6 days. The bacterial flagellum (4 days) and no evolution across 2 billion years lie within the time-frame that also links no evolution in coelacanths (in 65 million years) to the evolution of birds from dinosaurs (in 65 million years).
