Talk:Vibration theory of olfaction

From Wikipedia, the free encyclopedia

Isn't the "or more precisely, hypothesis" a little childish? It's every bit the theory that shape is but with more concrete evidence and better predictive power. Suggest a little more professional introduction?Cdubulous 04:10, 22 October 2007 (UTC)

Removed "some evidence supports shape theory" since no evidence I can find anywhere supports shape theory. If someone could come up with a convincing structure-odor relationship paper to cite on the shape theory page, it would make more sense to assert it here. It's far too vague right now. The Vosshall & Keller paper does not support vibration and is consistent with a shape-based theory, but it does not confirm any particular prediction of shape theory, especially since one of their findings, that a mixture of guiacol and benzaldehyde does not produce a vanilla illusion, in fact contradicts the weak shape theory, since guiacol and benzaldehyde together constitute the shape of vanillin and a receptor system recognizing pieces in a mixture should feel all the bits of vanillin.
