Humans helped drive a species of giant turtle to extinction almost 3,000 years ago, according to study in PNAS.
It is one of the first cases that clearly shows that humans played a role in the demise of the giant, extinct animals known as "megafauna".
An Australian research team discovered turtle leg bones - but not shells or skulls - on an island of Vanuatu.
The bones date to just 200 years after humans' arrival, suggesting they were hunted to extinction for their meat.
