I study birds at the American Museum of Natural
History, but Im also crazy about tigers. Ive used
to study a type of tiger that lives on the island
of Sumatra in Indonesia. Several thousand years ago, the islands
of Indonesia were connected to mainland Asia, and all the
tigers roamed freely. Gradually, the islands separated and
Sumatran tigers became isolated.
compared the DNA of Sumatran tigers to that of other kinds
of tigers, such as Bengals and Siberians. We discovered that
are genetically unique. Scientists can use
this information to make decisions about how to breed tigers
in zoos. This discovery will also support Indonesias
efforts to protect tigers in the wild.
