This research is an outgrowth of recent paleontological expeditions to Madagascar. The research include: (1) Functional anatomy of extinct lemurs, encompassing descriptions and functional interpretations of previously unknown carpal and pedal materials, vertebrae, and pelves. The goals are reconstruction of positional behavior of extinct lemurs, description of new species, and analysis of patterns of long bone structural adaptation. (2) Lemur evolutionary ontogeny. Indroids (including the giant extinct forms) have patterns of dental and somatic growth that are exceedingly unusual for primates. Available ontogenetic series will be examined and compared, using new analytical strategies. (3) Geographic variation, sexual variation and phylogeny of lemurs. A multivariate analysis of subfossil lemur skeletal variation will be conducted and a taxonomic revision of the lemurs will be undertaken, including phenetic and cladistic treatments of characters previously studied only among extant lemurs. Interactive activities include a course on "The Evolution of Ontogeny" and a graduate seminar designed according to student needs on topics such as: problems in allometry, mathematical modelling in evolutionary biology, sexual dimorphism, the evolution and extinction of Malagasy primates. In addition, guest lectures will be offered with special emphasis on subfossil lemurs.

这项研究是最近马达加斯加古生物学考察的成果。 研究包括：（1）已灭绝狐猴的功能解剖学，包括对以前未知的腕骨和足部材料、椎骨和骨盆的描述和功能解释。 目标是重建已灭绝狐猴的位置行为、描述新物种以及分析长骨结构适应模式。 (2)狐猴进化个体发育。 类人猿（包括已灭绝的巨型物种）的牙齿和躯体生长模式对于灵长类动物来说是极其不寻常的。 将使用新的分析策略对可用的个体发生系列进行检查和比较。 (3)狐猴的地理变异、性别变异和系统发育。 将对亚化石狐猴骨骼变异进行多变量分析，并对狐猴进行分类学修订，包括对以前仅在现存狐猴中研究的特征进行表型和分支处理。 互动活动包括“个体发育的进化”课程和根据学生需求设计的研究生研讨会，主题包括：异速生长问题、进化生物学的数学模型、两性二态性、马达加斯加灵长类动物的进化和灭绝。 此外，还将提供客座讲座，重点关注亚化石狐猴。
