¿CO-EVOLUCIÓN MORFOLÓGICA ENTRE LOS PICOS DE LOS COLIBRÍES Y LAS COROLAS DE LAS PLANTAS?

Resumen

In studies of the hummingbird-plant interaction the researchers have observed a pattern in
which these organisms seem to be associated according to the morphological adjustment
between hummingbird´s peaks and plant´s corollas, and is believed to be the result of
morphology co-evolution between these structures, but, certain facts not consistent with this
idea could lead to another interpretation of the phenomenon. I propose a diferent idea through
analysis from: the morphological and ecological generalism in the interaction, and the
importance of nectar for hummingbirds, phenomena that could explain the pattern. Probably
the morphology of hummingbird´s peak and plant´s corollas have different causes to the
interaction.
