Location of Madagascar

Madagascar, officially the Republic of Madagascar, is an island country comprising the island of Madagascar and numerous smaller peripheral islands. Lying off the southeastern coast of Africa, it is the world's fourth largest island, the second-largest island country and the 44th largest country in the world. Its capital and largest city is Antananarivo.

Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from Africa during the Early Jurassic, around 180 million years ago, and split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation; consequently, it is a biodiversity hotspot and one of the world's 17 megadiverse countries, with over 90% of wildlife being endemic. The island has a subtropical to tropical maritime climate. Madagascar was first settled during or before the mid-first millennium AD by Austronesian peoples, presumably arriving on outrigger canoes from present-day Indonesia. These were joined around the ninth century AD by Bantu migrants crossing the Mozambique Channel from East Africa. Other groups continued to settle on Madagascar over time, each one making lasting contributions to Malagasy cultural life. Consequently, there are 18 or more classified peoples of Madagascar, the most numerous being the Merina of the central highlands.

Until the late 18th century, the island of Madagascar was ruled by a fragmented assortment of shifting sociopolitical alliances. Beginning in the early 19th century, most of it was united and ruled as the Kingdom of Madagascar by a series of Merina nobles. The monarchy was ended in 1897 by the annexation by France, from which Madagascar gained independence in 1960. The country has since undergone four major constitutional periods, termed republics, and has been governed as a constitutional democracy since 1992. Following a political crisis and military coup in 2009, Madagascar underwent a protracted transition towards its fourth and current republic, with constitutional governance being restored in January 2014.

Ambondro mahabo is a mammal from the Middle Jurassic (Bathonian) Isalo III Formation (about 167 million years ago) of Madagascar. The only described species of the genus Ambondro, it is known from a fragmentary lower jaw with three teeth, interpreted as the last premolar and the first two molars. The premolar consists of a central cusp with one or two smaller cusps and a cingulum (shelf) on the inner, or lingual, side of the tooth. The molars also have such a lingual cingulum. They consist of two groups of cusps: a trigonid of three cusps at the front and a talonid with a main cusp, a smaller cusp, and a crest at the back. Features of the talonid suggest that Ambondro had tribosphenic molars, the basic arrangement of molar features also present in marsupial and placental mammals. It is the oldest known mammal with putatively tribosphenic teeth; at the time of its discovery it antedated the second oldest example by about 25 million years.

Upon its description in 1999, Ambondro was interpreted as a primitive relative of Tribosphenida (marsupials, placentals, and their extinct tribosphenic-toothed relatives). In 2001, however, an alternative suggestion was published that united it with the Cretaceous Australian Ausktribosphenos and the monotremes (the echidnas, the platypus, and their extinct relatives) into the clade Australosphenida, which would have acquired tribosphenic molars independently from marsupials and placentals. The Jurassic Argentinean Asfaltomylos and Henosferus and the Cretaceous Australian Bishops were later added to Australosphenida, and new work on wear in australosphenidan teeth has called into question whether these animals, including Ambondro, did have tribosphenic teeth. Other paleontologists have challenged this concept of Australosphenida, and instead proposed that Ambondro is not closely related to Ausktribosphenos plus monotremes, or that monotremes are not australosphenidans and that the remaining australosphenidans are related to placentals.

The Parti des déshérités de Madagascar (PADESM, "Party of the Disinherited of Madagascar") was a political party active in Madagascar from June 1946 into the First Republic (1960–1972). It was formed in reaction to the establishment and rapid political success of the Mouvement démocratique de la rénovation malgache (MDRM) political party, formed by Merina elites on a platform of independence from France. While nationalism - and therefore the MDRM - had widespread support from all ethnic communities, PADESM championed the empowerment and equitable government of coastal peoples, who had historically been subjugated by the Merina and feared the MDRM could ensure their return to political dominance upon independence. They actively recruited and campaigned along ethnic lines, initially including coastal peoples and the descendants of Merina slaves, but eventually excluding the latter entirely. The formation and political success of PADESM was actively fostered by the French colonial administration, which manipulated election results in favor of the coastal party.

The nationalist Malagasy Uprising of 1947 led the French colonial administration to dissolve the MDRM and temporarily suspend all other political parties, including PADESM. Tensions between the parties played out during the uprising through targeted acts of violence between supporters of the rival groups. An estimated 1,900 to 5,000 PADESM supporters were killed during the uprising by pro-MDRM nationalist fighters. After the nationalist movement was crushed in December 1948, PADESM experienced an increase in popularity, aided by continuing French support. The party won several key political elections in the 1950s. Nevertheless, as the process toward independence began, it became fragmented between conservative and progressive factions, with the latter splitting off in December 1956 to form the Parti sociale démocrate (PSD, Social Democratic Party). With this split and independence in 1960, PADESM became moribund. (Full article...)
