摘要

孔子鸟目是鸟类最基础的分支之一,是揭示鸟类飞行早期进化的理想分支。鸟类的后肢功能多样,包含了大量关于它们行为的信息。然而,目前对孔子鸟后肢的研究仅在功能形态学方面进行了详细的研究,直接评估其运动能力的定量研究相对缺乏。这就导致了对孔子行为的一些争议。本文综述了关于孔子鸟的生活习性和起飞能力的争论,这与孔子鸟的后肢功能密切相关。采用工程技术,包括长骨的几何分析、肌肉的生理重建、运动学和动力学特征的估计以及附肢运动机制的分析,推荐了几种方法来估计孔子鸟的后肢功能。考虑到化石骨骼易碎,形状不规则,通常会变形,因此将计算机数值模拟技术应用于此类研究是合适的。充分的功能定量研究将有助于厘清早期鸟类的运动行为,为进一步探索鸟类飞行和早期鸟类运动的起源提供线索和证据。

Reconstruction of the Hindlimb Locomotion of Confuciusornis (Aves) and Its Implication for the Origin of Avian Flight
As one of the most basal avian clades, the Confuciusornithids are ideal in revealing the early evolution of avian flight. Birds’ hindlimbs are functionally diverse and contain a wealth of information about their behavior. The hindlimb of Confuciusornis, however, has only been studied in detail in terms of functional morphology, and quantitative studies that directly assess locomotor ability are relatively lacking. This has led to certain controversies on the behavior of Confuciusornis. This paper reviews the debates over the life habits and take-off ability of Confuciusornis, which are closely related to their hindlimb function. Several methodologies adopted engineering techniques, including the geometrical analysis of long bones, physiological reconstruction of muscles, kinematic and kinetic characteristics estimating, and appendage locomotor mechanism analysis, are recommended for estimating the hindlimb functions of Confuciusornis. Considering that the fossil bones are fragile, irregular in shape, and usually deformed, it is appropriate to apply computer numerical simulation techniques to such studies. A sufficient functional quantitative study will help clarify early bird locomotor behavior, which will provide clues and evidence for further exploration of the origin of bird flight and early bird movement.

期刊介绍: The field of biomechanics concerns with motion, deformation, and forces in biological systems. With the explosive progress in molecular biology, genomic engineering, bioimaging, and nanotechnology, there will be an ever-increasing generation of knowledge and information concerning the mechanobiology of genes, proteins, cells, tissues, and organs. Such information will bring new diagnostic tools, new therapeutic approaches, and new knowledge on ourselves and our interactions with our environment. It becomes apparent that biomechanics focusing on molecules, cells as well as tissues and organs is an important aspect of modern biomedical sciences. The aims of this journal are to facilitate the studies of the mechanics of biomolecules (including proteins, genes, cytoskeletons, etc.), cells (and their interactions with extracellular matrix), tissues and organs, the development of relevant advanced mathematical methods, and the discovery of biological secrets. As science concerns only with relative truth, we seek ideas that are state-of-the-art, which may be controversial, but stimulate and promote new ideas, new techniques, and new applications.
