[ES] La forma de la cola y la eficacia del vuelo en la Golondrina Común: ¿selección natural o selección sexual? En este trabajo se discuten algunos problemas metodológicos graves que afectan a las conclusiones presentadas en un artículo reciente, publicado por Evans (1998) en la revista Nature, sobre la evolución de la forma de la cola en los machos de Golondrina Común Hirundo rustica. Se concluye que la interpretación desarrollada en ese artículo debe ser considerada con mucha cautela y que la importancia relativa de la selección natural en la evolución de la cola de los machos de Golondrina Común está aún por determinar, sobre todo en comparación con el bien establecido papel de la selección sexual en la evolución de este carácter.
[EN] Tail streamers and flight performance in Barn Swallows: natural or sexual selection? The paper of Evans (1998) published in the journal Nature on the evolution of tail streamers in male Barn Swallows Hirundo rustica is discussed in the light of some methodological problems commited by this author. The conclusions are that the interpretation of Evans’ results must be taken with caution and that the importance of natural selection, as compared with the well established role of sexual selection, in the evolution of tail streamers in Barn Swallows remains to be assessed.
