英文摘要The recently described specimen of Sapeornis with feathers around the ankle joint is the first finding of birds with metatarsal feathers. The discovery of several groups of paravians with feathered distal hindlimbs has been used as evidence that flight in Ayes evolved through the tetrapteryx stage. However, most specimens of Sapeornis do not preserve feathers around the feet, and these feathers are clearly absent in at least one exceptional specimen preserving skin and feather impressions. This suggests that the presence of ankle feathers in Sapeornis may alternatively he interpreted as ornamentation. Basal birds show more ornamental tail morphologies than aerodynamic ones suggesting that sexual selection played a dominant role in shaping tail plumage. Feathers on the forelimbs initially evolved for a purpose other than flight, and we propose aerodynamics was not the driving force in the hindlimb feather evolution. Feathers appear to be means of visual communication playing a very important role in the evolution of paravian plumage.
