1967 年，G.G.辛普森描述了来自肯尼亚中新世早期沉积物的三个部分下颌骨，他将其解释为属于一种新的链球菌灵长类动物普罗波托。这种解释很快就受到了挑战，有人断言普罗波托不是灵长类动物，而是翼足类果蝠。近半个世纪以来，后一种解释没有受到质疑。在这里，我们重新评估了 Propotto 的亲和力，利用各种证据来确定这种奇怪的哺乳动物是链球菌灵长类动物，正如辛普森最初提出的那样。此外，我们的系统发育分析支持将 Propotto 与来自埃及的始新世晚期古猿一起视为非洲干手形狐猴，与马达加斯加现存的狐猴 (Daubenonia) 完全相关。我们的研究结果挑战了长期以来的观点，即所有狐猴都是马达加斯加的单一古代殖民地的后裔，并提出了一种有趣的替代方案，其中两个狐猴谱系独立地从非洲分散到马达加斯加，可能是在新生代后期。化石分类群 Propotto 最初被认为是灵长类动物，但目前被广泛解释为蝙蝠。在这里，作者将 Propotto 鉴定为干手性狐猴，并根据系统发育分析，提出马达加斯加的两个独立的狐猴殖民。
In 1967 G.G. Simpson described three partial mandibles from early Miocene deposits in Kenya that he interpreted as belonging to a new strepsirrhine primate, Propotto. This interpretation was quickly challenged, with the assertion that Propotto was not a primate, but rather a pteropodid fruit bat. The latter interpretation has not been questioned for almost half a century. Here we re-evaluate the affinities of Propotto, drawing upon diverse lines of evidence to establish that this strange mammal is a strepsirrhine primate as originally suggested by Simpson. Moreover, our phylogenetic analyses support the recognition of Propotto, together with late Eocene Plesiopithecus from Egypt, as African stem chiromyiform lemurs that are exclusively related to the extant aye-aye (Daubentonia) from Madagascar. Our results challenge the long-held view that all lemurs are descended from a single ancient colonization of Madagascar, and present an intriguing alternative scenario in which two lemur lineages dispersed from Africa to Madagascar independently, possibly during the later Cenozoic. The fossil taxon Propotto was originally identified as a primate, but is currently widely interpreted as a bat. Here, the authors identify Propotto as a stem chiromyiform lemur and, based on phylogenetic analysis, suggest two independent lemur colonizations of Madagascar.
