For the first time, scientists have mapped the genome--the genetic code--of orangutans. This new tool may be used to support efforts to maintain the genetic diversity of captive and wild orangutans. The new map of the orangutan genome may also be used to help improve our understanding of the evolution of primates, including humans.
Partially funded by the National Science Foundation, the orangutan study appears in the Jan. 27 issue of Nature. It was conducted by an international team of scientists led by Devin P. Locke of the Genome Center at Washington University.
The name "orangutan" is derived from the Malay term, "man of the forest," a fitting moniker for one of our closest relatives.
There are two species of orangutans, defined primarily by their island of origin--either Sumatra or Borneo. The outlook for orangutan survival is currently dire because there are estimated to be only about 7,500 orangutans in Sumatra, where they are considered critically endangered, and only about 50,000 orangutans in Borneo, where they are considered endangered.
The endangerment status of orangutans is determined by the International Union for Conservation of Nature.
There are no other wild populations of orangutans other than those in Sumatra and Borneo. The decline of the Sumatran and Borneo populations of orangutans is caused by varied threats, such as illegal logging, the conversion of rain forests to farmland and palm oil plantations, hunting and diseases.
Using a mix of legacy and novel technologies, the research team mapped the genomes of a total of 11 orangutans, including representatives of both the Sumatran and Bornean species.
The map of the orangutan genome may support conservation efforts by helping zoos create breeding programs designed to maintain the genetic diversity of captive populations. (The greater the genetic diversity of a species, the more resil
