"Comes to an end"

Bold words. While this demonstrates that the locus of tympanic formation differs across vertebrates, the mechanism (fenestration and ossicles from mandibles) apparently remains the same - either way, I can't see how this is "case closed".

Aborting a chicken fetus for science seems a lot less barbaric then raising and killing animals as an unnecessary food source.

> Hear, hear for genetics!

Wow, those Japanese researchers can now sure beat their drums about this research.

What a ... jaw-dropping result.
