Analysis of the remains of the recently discovered Aerosteon riocoloradensis shows signs that it used an intermediary lung type between reptiles and birds. Cool stuff.

Could we maybe say exaptation or co-option instead? Pre-adaptation has distinctly teleological overtones.

TTFN,

I considered using exaption; it's both a better term and the one the article actually uses but I chose "pre-adaption" as I think it is a better known term.

(edit)Actually, thinking about it I'm not sure exaption is a better term. Pre-adaption had the distinct advantage that it explains what it is talking about in a way that exaption doesn't; it's a term you can understand rather than simply knowing. There is a problem with teleological misunderstandings; but I'm not convinced that the possibility of such is a good reason to use a different term.

Edited by Mr Jack, : More thoughts
