Cladistic analysis of the total ontogenetic pattern of the fetal membranes and placenta in all extant primate superfamilies provides clear evidence of a strepsirhine-haplorhine dichotomy in the order Primates. The suborder Prosimii appears to be a paraphyletic taxon, based on the retention of numerous primitive character states in tarsiers and strepsirhines. Fetal membrane evidence supports the sister group relationship of Tarsiiformes and Anthropoidea in the suborder Haplorhini, based on their possession of shared derived characters. Morphogenetic patterns of the fetal membranes and placenta in haplorhines are consistent with the concept of a monophyletic origin of Anthropoidea from an ancestral tarsilform stock.
对所有现存灵长目超科动物胎膜和胎盘的整体个体发育模式进行支序分析，为灵长目动物中湿鼻猴类和干鼻猴类的二分法提供了明确证据。基于跗猴和湿鼻猴保留了众多原始特征状态，原猴亚目似乎是一个并系分类单元。胎膜证据支持跗猴型下目（Haplorhini）中跗猴形类和类人猿亚目的姐妹群关系，因为它们具有共同的衍生特征。干鼻猴类胎膜和胎盘的形态发生模式与类人猿从祖先跗猴形类种群单系起源的概念一致。
