红毛猩猩被广泛认为是一种高度二型的物种。个体发生学的方法来研究两性异形可以帮助研究人员了解这些差异在哪里和何时发展。在这项研究中，来自婆罗洲的357只红毛猩猩被分为五个发育阶段，代表婴儿期到成年期。通过欧几里得距离矩阵分析（EDMA）（一种用于形式比较的定量方法）分析了来自代表面部和腭的16个标志的三维（3D）坐标数据。进行了三项单独的分析（特定年龄的静态形态比较、特定性别的生长轨迹分析和相对生长模式的两性比较），旨在描述猩猩面部和上颚的生长速率、时间、幅度和模式。结果表明，一般男性和女性共享一个类似的，但不完全相同的，增长或局部形式的变化模式，但不同的增长速度，时间，和差异的幅度。面部和上颚的双形可以局限于婴儿期，并可在所有年龄段追踪。从婴儿期到青春期，雌性猩猩的生长速度略快于雄性，此时雄性的生长速度超过雌性。女性的生长随着成年期的到来而停止，而男性的生长继续（即，二态维度的数量和大小都增加）。男性和女性在面部尺寸和与眼眶、上面部和腭宽相关的生长方面相似。它们在整个发展过程中保持着这些相似性。然而，他们在面部和鼻子的高度，腭长度，吻突出，鼻咽的深度，以及面部到头骨的连接方面有所不同。成年男性的面部变宽，颧骨显著地向外展开，与颊垫的发育相对应。虽然两性之间的生长模式相似，但它们在侧眼眶，吻突出和面部到颅骨的分叉方面有所不同。成人的二型性是一生中经历的生长模式的结果，并且在整个颅骨中并不相等地表达。了解二型性的模式，沿着的差异大小，可能有助于解释化石记录中的二型性。am.

The orangutan is widely recognized as a highly dimorphic species. An ontogenetic approach to the study of sexual dimorphism can assist researchers in understanding both where and when these differences develop. In this study, 357 orangutans from Borneo were divided into five developmental stages representing infancy to mature adulthood. Three‐dimensional (3D) coordinate data from 16 landmarks representing the face and palate were analyzed by means of a Euclidean distance matrix analysis (EDMA), a quantitative method for the comparison of forms. Three separate analyses (an age‐specific static comparison of forms, a sex‐specific analysis of growth trajectories, and an intersex comparison of patterns of relative growth) were carried out with the intent to describe the rate, timing, magnitude, and pattern of growth in the orangutan face and palate. The results indicate that generally males and females share a similar, but not identical, pattern of growth or local form change, but differ in growth rate, timing, and magnitude of difference. Dimorphism in the face and palate can be localized in infancy and traced throughout all age intervals. Orangutan females grow slightly faster than males from infancy to adolescence, at which time male growth exceeds female growth. Female growth ceases with the advent of adulthood, while male growth continues (i.e., both the number and magnitude of the dimorphic dimensions increase). Males and females are similar in facial dimensions and growth related to the orbits, upper face, and palate width. They maintain these similarities throughout development. However, they differ in facial and nasal height, palate length, snout projection, depth of the nasopharynx, and hafting of the face onto the skull. The face broadens and the zygomatic bone flares dramatically in adult males, corresponding to the development of cheek pads. While growth patterns are similar between the two sexes, they differ in the lateral orbit, snout projection, and hafting of the face onto the cranium. Adult dimorphism is the result of growth patterns experienced throughout life, and it is not equally expressed across the cranium. An understanding of patterns of dimorphism, along with the magnitude of difference, may be helpful for interpreting dimorphism in the fossil record. Am. J.
