在冠鸟中，涉及超细长气管的上声道的修改已经进化了很多次，它们的进化与声学信号和通信中的“大小夸大”假设有关，即较小的鸟类可以发出更大的声音。中国中新世晚期一种新灭绝的野禽（鸡形目：雉科）的骨骼化石，保存了一个细长的，盘绕的气管，代表了鸟类这种声音变化的最古老的化石记录，也是野鸡进化的第一个文献。该物种在雉科的系统发育位置尚未完全解决，但似乎记录了一个单独的独立起源，这在鸡形目的声音修改。该化石保存了一段盘绕的气管和其他遗迹，支持气管长度超过鸟类的身体。与类似大小的野鸡相比，这种灭绝的物种可能会产生较低基频和减少谐波的发声。在开放和封闭的栖息地生活在鸡形的这种声音功能的独立进化似乎并不与其他生物学因素或其开放的热带草原样栖息地。化石中的特征通常与性二态性有关，这表明性选择可能导致了这种灭绝物种的形态和发声机制的进化。
Modifications to the upper vocal tract involving hyper-elongated tracheae have evolved many times within crown birds, and their evolution has been linked to a ‘size exaggeration’ hypothesis in acoustic signaling and communication, whereby smaller-sized birds can produce louder sounds. A fossil skeleton of a new extinct species of wildfowl (Galliformes: Phasianidae) from the late Miocene of China, preserves an elongated, coiled trachea that represents the oldest fossil record of this vocal modification in birds and the first documentation of its evolution within pheasants. The phylogenetic position of this species within Phasianidae has not been fully resolved, but appears to document a separate independent origination of this vocal modification within Galliformes. The fossil preserves a coiled section of the trachea and other remains supporting a tracheal length longer than the bird’s body. This extinct species likely produced vocalizations with a lower fundamental frequency and reduced harmonics compared to similarly-sized pheasants. The independent evolution of this vocal feature in galliforms living in both open and closed habitats does not appear to be correlated with other factors of biology or its open savanna-like habitat. Features present in the fossil that are typically associated with sexual dimorphism suggest that sexual selection may have resulted in the evolution of both the morphology and vocalization mechanism in this extinct species.
