Response to Comment on "A Well-Preserved Archaeopteryx Specimen with Theropod Features"
Gerald Mayr* and
D. Stefan Peters
We agree that statistical support for our proposed phylogeny
is weak, but the monophyly of Aves favored by most current researchers
is also weakly supported. In the absence of unambiguous apomorphies
of a clade including
Archaeopteryx and
Confuciusornis but not
deinonychosaurs, we do not believe that the statistical comparisons
made by Corfe and Butler challenge our hypothesis regarding
the ancestry of birds.
