Indians
migrating to Australia more than 4,000 years ago may have introduced dingoes to
the island continent, along with novel stone tools and new ways to remove
toxins from edible plants, researchers say.
Australia
was thought to have remained largely isolated from the rest of the world
between its initial colonization about 40,000 years ago by the ancestors
of aboriginal
Australians and the arrival of Europeans in the late 1800s.
"Outside
Africa, aboriginal
Australians are the oldest continuous population in the world,"
said researcher Irina Pugach, a molecular anthropologist at the Max Planck
Institute for Evolutionary Anthropology in Leipzig, Germany.
