A team led by scientists at the University of Washington and special agents with the U.S. Department of Homeland Security has used genetic testing of ivory shipments seized by law enforcement to uncover the international criminal networks behind ivory trafficking out of Africa. The genetic connections across shipments that they've uncovered exposes an even higher degree of organization among ivory smuggling networks than previously known.
The paper, published Feb. 14 in the journal Nature Human Behaviour, incorporates results from DNA testing of more than 4,000 African elephant tusks from 49 different ivory seizures made in 12 African nations over a 17-year period.
