The question of what makes a feather a feather has become rather heated in the recent past, with the discovery in China in the 1990s of fossilized dinosaurs like the Sinorthosaurus (Chinese-bird-dinosaur), with branching skin appendages on its skin. "Some say these things are feathers, some say they're protofeathers, others say they're not feathers at all," Chuong explains. "Everybody wants to know which one is the real first feather."

Time for a heated discussion of chicken feathers, eh?

Jurassic Chicken PING!

What came first, the chicken or the feather.

It's all a lie, I tell you!  I have personally disproven evolution, chemistry, astronomy, geology and all other false atheistic, Nazi communist one-world government scientific slime!

from hairs to lung tissue to mammary glands

When I was in college, research into the nature and origin of mamary glands was also of prime interest.

This interaction between evolutionary biology and developmental biology (dubbed Evo-Devo) is a relatively new marriage of two previously disparate fields.

Are we not men??

We are DEVO!!

Evo-Devo Bump.

"These results suggest that the barbs form first and later fuse to form a rachis, much like downy feathers are formed before flight feathers when a chicken grows up. Under the general rule of ontogeny repeating phylogeny, downy feather made only of barbs probably appeared before the evolution of feathers with rachides and capable of flight," Chuong says.

Ontogeny recapitulating phylogeny is one of those mistaken ideas like that went out like Lamarkism.

Strange comment.

The Nature article has very little about the "evo" part of the "evo-devo" study.

This is pterrible.

Totally awesome findings. My midnight basketball league buds tonite will he thunderstruck. Can't wait for the Malkin and Coulter take on it all.
