哺乳动物动力飞行的进化需要从祖先的肢体形态到适合飞行的肢体形态的特定发育转变。通过比较形态发生的研究，研究人员已经量化了分歧点和分歧率，为了解哺乳动物翅膀的进化提供了重要的见解。在这里，我比较蝙蝠和大鼠（褐家鼠）提供的祖先状态之间的前肢的生长，发育和骨骼发育和量化的生长轨迹，说明形态的发展和进化上的分歧。此外，我将讨论如何在形态发育过程中控制翅膀形状的翼骨和翼膜的多变量分析，并讨论如何在飞行个体发育过程中稳定飞行动力学。此外，我将讨论蝙蝠的个体发育生态位和青少年如何影响种群觅食模式的飞行的发展。此外，我提供了一个假设的个体发育景观模型，预测如何以及何时选择是最激烈的少年形态建成和测试这个模型的数据从人口的小棕蝠，鼠耳蝠lucifugus。版权所有（C）2007 S.

The evolution of powered flight in mammals required specific developmental shifts from an ancestral limb morphology to one adapted for flight. Through studies of comparative morphogenesis, investigators have quantified points and rates of divergence providing important insights into how wings evolved in mammals. Herein I compare growth, development and skeletogenesis of forelimbs between bats and the more ancestral state provided by the rat ( Rattus norvegicus) and quantify growth trajectories that illustrate morphological divergence both developmentally and evolutionarily. In addition, I discuss how wing shape is controlled during morphogenesis by applying multivariate analyses of wing bones and wing membranes and discuss how flight dynamics are stabilized during flight ontogeny. Further, I discuss the development of flight in bats in relation to the ontogenetic niche and how juveniles effect populational foraging patterns. In addition, I provide a hypothetical ontogenetic landscape model that predicts how and when selection is most intense during juvenile morphogenesis and test this model with data from a population of the little brown bat, Myotis lucifugus.
