Gunnell, G, Boyer, D. M., Friscia, A. R., Heritage, S, Manthi, F. K., Miller, E. R., Sallam, H. M., Simmons, N. B., Stevens, N. J., and Seifert, E. R. (2018). Fossil lemurs from Egypt and Kenya suggest an African origin for Madagascar’s aye-aye. Nature Communications. Published online August 21, 2018. Doi: 10.1038/s41467-018-05648-w.
This paper studies the propotto, an ancient primate researched by G.G. Simpson, in 1967, in Kenya. His study was later challenged to prove that the propotto was not necessarily a primate but a ‘pteropodid fruit bat’ (pp. 1). While this interpretation was never challenged again, this paper conducts studies to prove that these animals were indeed not only primates, but also are a form of ‘African stem chiromyiform lemurs’ (pp. 1), which are in turn related to the species ‘aye-aye’ (pp. 1) of Madagascar. Along with this this paper, with their phylogenic studies simultaneously researches the possibility that the Madagascar lemurs did not come down from a single colonial species but from two different independent lineages, with origin in Africa. The study was mainly conducted by observing the dental build-up of the propotto and a related primate ‘presiopithicus’ (pp. 2) with the aye-aye, also called the ‘Daubentonia’ (pp. 1, 2) . This paper is a thorough follow-up to the papers where scientists were researching the reasons and methods of the lemur species shift from Africa to Madagascar.

This research papers deals with the extinction of various species of lemurs in the Madagascar, primarily due to over-population leading to the destruction of habitats for their breeding and also hunting. Certain species like archeolemurids and megalanapids (Gunnell, G. 2018, pp. 2) which are already extinct were used for phylogenic studies to determine the risk factors involved in the survival of the currently extant species like lemurids, indriids and lepilemurids. The 2 specific extinct species, phylogenetically studied with their fossils revealed that they were not related and their population was not very big. Thus, their big size would not have been a reason for protection against their extinction. But the 8 extant species’ study revealed no such “relationship between body size and diversity” (pp. 45). Thus, to enhance protection for the remaining species, size may not be a factor to be considered.
