Answer 2

The origins of Onge tribe in Andamans can be traced by studing their DNA.

Mitochondrial DNA analysis helps us to trace our ancestors upto a thousand years.

MDNA analysis uses extremely old bones from dead bodies as subject matter instead of hair samples.

It is used only in those cases where the common techniques of origin tracing have failed.
