Archaeopteryx gets a brain scan
There are two articles on the brain of _Archaeopteryx_ in tomorrow's Nature,
which conclude "that _Archaeopteryx_ was probably equipped for flight."
"Inside the oldest bird brain" - Lawrence Witmer
"The avian nature of the brain and inner ear of _Archaeopteryx," by Patricio
Dominguez, Angela C. Milner, Richard A. Ketcham, M. John Cookson and Timothy B.
"The remodelling of the brain towards the avian condition must have begun well
before the appearance of _Archaeopteryx_ 147 million years ago in the latest
Jurassic. The convergent increase in visual and vestibular regions in
pterosaurs(19) is further evidence that both an aerodynamic wing and a powerful
central nervous system are integral to powered flight."
