基于ε-珠蛋白基因序列，研究了不同灵长类群体之间的系统发育关系。对5种链霉菌属灵长类的ε-珠蛋白基因进行了测序。将这些序列与其他已知的灵长类ε-珠蛋白序列进行比对和比较，包括来自另外两种链鼻猴、一种眼镜猴、19种新世界猴（代表所有现存属）和5种卡他鼻猴的数据。此外，ε-珠蛋白基因上游的一个2-kb片段在两个链霉菌中进行了测序。该上游序列与其他五种灵长类动物进行了比对，这些灵长类动物的数据可在本节中获得。家兔和山羊作为外群。这一分析支持灵长目的单系性，但不支持传统的原猴亚目中的眼镜猴、兜猴和狐猴的分类;相反，它支持眼镜猴和狐猴的姐妹分类为单鼻目，兜猴和狐猴的姐妹分类为链鼻目。鼠狐猴（Microcebus murinus）和侏儒狐猴（Cheirogaleus medius）似乎彼此关系最密切，与狐猴科形成一个分支，并且可能与兜猴科没有密切关系，正如一些形态学研究所表明的那样。对ε-珠蛋白数据的分析支持了这样的假设，即狐猴（马达加斯加狐猴）与其他马达加斯加链鼻猴（都被归类为狐猴）有姐妹群关系。ceboids之间的关系同意从以前的ε-珠蛋白的研究，其中较少的外群类群。分子进化的速度在lorisoids比在狐猴。
Phylogenetic relationships among various primate groups were examined based on sequences of ε-globin genes. ε-globin genes were sequenced from five species of strepsirhine primates. These sequences were aligned and compared with other known primate ε-globin sequences, including data from two additional strepsirhine species, one species of tarsier, 19 species of New World monkeys (representing all extant genera), and five species of catarrhines. In addition, a 2-kb segment upstream of the ε-globin gene was sequenced in two of the five strepsirhines examined. This upstream sequence was aligned with five other species of primates for which data are available in this segment. Domestic rabbit and goat were used as outgroups. This analysis supports the monophyly of order Primates but does not support the traditional prosimian grouping of tarsiers, lorisoids, and lemuroids; rather it supports the sister grouping of tarsiers and anthropoids into Haplorhini and the sister grouping of lorisoids and lemuroids into Strepsirhini. The mouse lemur (Microcebus murinus) and dwarf lemur (Cheirogaleus medius) appear to be most closely related to each other, forming a clade with the lemuroids, and are probably not closely related to the lorisoids, as suggested by some morphological studies. Analysis of the ε-globin data supports the hypothesis that the aye-aye (Daubentonia madagascariensis) shares a sister-group relationship with other Malagasy strepsirhines (all being classified as lemuroids). Relationships among ceboids agree with findings from a previous ε-globin study in which fewer outgroup taxa were employed. Rates of molecular evolution were higher in lorisoids than in lemuroids.
