Females of other species of placental mammal undergo estrous cycles, in which the endometrium is completely reabsorbed by the animal (covert menstruation) at the end of its reproductive cycle. His suggestion was not followed as the establishment of a breeding colony of macaques at the Carnegie Institution of Washington provided a better alternative. This represents only 1.5% of the known 5502 mammalian species and <0.09% of these are nonprimates. BACKGROUND: Menstruation occurs only in higher primates, some bats, the spiny mouse and the elephant shrew. Our knowledge of the latter species is due to work by C. J. van der Horst. African Wildlife Foundation engages government entities to help plan and propose alternative solutions to habitat fragmentation by providing our scientists and researchers as resources to assist in proper planning and ultimately ensuring there is a balance between modernization and conservation.

Given the distribution of menstruation, it is highly unlikely that the ancestor of placental mammals exhibited menstruation. Menstruation has not been detected or studied in the majority of bat species; thus, it is unclear if menstruation evolved twice within Chiroptera or is more widespread in the clade. Menstruation – the regular renewal of the lining of the uterus – is a curious phenomenon. A new species of giant sengi or elephant‐shrew (genus Rhynchocyon) highlights the exceptional biodiversity of the Udzungwa Mountains of Tanzania. Our knowledge of the latter species is due to work by C. J. van der Horst. Their traditional common English name elephant shrew comes from a perceived … The East African long-eared elephant shrew (Elephantulus rufescens) carries a type of malaria that humans apparently cannot contract. Menstruation evolved relatively recently in each of these three mammalian groups. Menstruation, the cyclical shedding of the decidualized endometrium in the absence of pregnancy, is believed to be limited to 78 higher-order primates (human beings and Old World monkeys), 4 species of bat, and the elephant shrew. They move through the world like wee baby elephant-bunnies, snuffling on all … BACKGROUND: Menstruation occurs only in higher primates, some bats, the spiny mouse and the elephant shrew.

J. Zool. In addition, there is compelling evidence for menstruation in elephant shrew, which is a small-size mammal found exclusively in Africa.
