The evoluTion of Tail Shape in hummingbirdS
Resumen.—La morfología de la cola de muchas aves ha sido moldeada tanto por selección natural como por selección sexual. Algunos modelos de la aerodinámica de la cola predicen que las funciones relacionadas con el vuelo implican una presión de selección natural para tener colas con formas moderadamente ahorquilladas, lo que limitaría la tendencia de la selección sexual a generar diversidad morf...
متن کاملSlow rate of molecular evolution in high-elevation hummingbirds.
Estimates of relative rates of molecular evolution from a DNA-hybridization phylogeny for 26 hummingbird species provide evidence for a negative association between elevation and rate of single-copy genome evolution. This effect of elevation on rate remains significant even after taking into account a significant negative association between body mass and molecular rate. Population-level proces...
متن کاملDevelopmental plasticity in sexual roles of butterfly species drives mutual sexual ornamentation.
Current explanations for why sexual ornaments are found in both sexes include genetic correlation, same sex competition, and mutual mate choice. In this study, we report developmental plasticity in mating behavior as induced by temperature during development in the butterfly Bicyclus anynana. Males and females reciprocally change their sexual roles depending on their larval rearing temperatures...
متن کاملHummingbirds
easily fill an article or, indeed, a monograph. This systematic screen for developmental mutations has revolutionized developmental genetics, and it provides a veritable Who’s Who of developmental regulatory genes, each of which has given rise to an entire cottage industry of research. Of course the two papers also led directly to a Nobel Prize, which just means that they have good taste in Sto...
