Taxonomy, geographic variation & population genetics of Bornean & Sumatran orangutans

1.1 Introduction
#The orangutan was first described in the early seventeenth century by two Dutch physicians, Jacob de Bondt and Nicholaas Tulp, and then assigned a taxonomic name, Simia satyrus, by Carl von Linné,
a name which was subsequently changed to Pongo pygmaeus in 1927 by the International Commission on Zoological Nomenclature (for more details, see Rijksen and Meijaard 1999)
#Despite a wide Pleistocene distribution in South East Asia and
mainland Asia, including areas between Vietnam,northern India and southern China (Hooijer 1948; Kahlke 1972; von Koenigswald 1982; Tougard and Ducrocq 1999; Bacon and Long 2001), wild orangutan
populations are today found only in Northern Sumatra and Borneo. These two islands are isolated from each other by the South China Sea, an isolation that has been effective for at least 8000 years
(Harrison et al. 2006). Sub-fossil orangutans are limited but G nds dated at 30,000–40,000 before the present (BP) have been discovered in both Sumatra and Borneo (Smith and Pilbeam 1980)
