I had two questions about Paul's text.

1) "Nudds and Dyke (Reports, 14 May 2010, p. 887) reported that the primary
features of the early birds Archaeopteryx and Confuciusornis were too weak to
power flight"

What are these "primary features" that Paul describes? How do these features
confer weakness on the animals in question?

I suspect that is a typo -- and is supposed to read "primary feathers"...
