Capsaicin is a compound in chili peppers that produces a burning sensation in mammalian tissues.  In mammals, capsaicin binds to the TRPV1 transmembrane channel.  Interestingly, the TRPV1 channel in birds does not respond to capsaicin.  What implications could this have for chili pepper plants?

A. Chili pepper seeds cannot be dispersed.
B. Mammals are likely responsible for the dispersal of chili pepper seeds.
