Hoolock gibbon



  • The Centre for Cellular and Molecular Biology (CCMB) study has found that there is only one species of Hoolock gibbons and not two in India.


  • The Western Hoolock gibbons (Hoolock Hoolock) are the only apes in India. The other species, Mishmi Hills gibbons (Hoolock leuconedys), is not present here.
  • There was confusion before as these small apes present in the northeast have populations had different physical features.
  • The CCMB team corroborated the data with mitogenome (genetic information contained in mitochondria) analysis and estimated that the split between two species occurred 1.49 million years ago.
  • The new findings will help design conservation programmes by inter-breeding the two populations and maintain their genetic diversity.
