  "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".

  > Hear, hear for genetics! Wow, those Japanese researchers can now sure beat their drums about this research. What a ... jaw-dropping result.

  This research seems barbaric.

    Aborting a chicken fetus for science seems a lot less barbaric then raising and killing animals as an unnecessary food source.
    • dempseye 11y ago
      I agree.
