Andaman tribes may have a new human ancestor

It was considered in earlier studies that tribes of the Andaman Islands are distinct from the mainland Indian population. Two tribal communities of the Andaman Islands, Jarawas and Onges , may have evolved from an as yet unknown human ancestor.

 

The genetic analysis done by a joint team of Indian and Spanish scientists and their claim, although not yet backed by any fossil evidence, is sensational as another unknown branch to human ancestry can be found after this.

 

Scientists at the National Institute of Bio-Medical Genetics (NIBMG), Kalyani, West Bengal, working with those from the Pompeu Fabra University, Barcelona, Spain made this discovery after analyzing ten genetic samples derived from Jarawas and Onges in the Andamans.

 

From what is known of human evolution, those that went west evolved into the Neanderthals while those that migrated east formed the Denisovans. A deep study needed to know that whether this could be a third ancient human type.

 

The study has been published in the scientific journal Nature Genetics, which showcased results of 60 samples drawn from different ethnic groups across India.
