The Wire

The famous Macadamia nut. They’re an iconic staple of Australia, with indigenous people cultivating and eating them for thousands of years before the west ever got them in their cookies. It was a delicacy,  used to trade between tribes and even used as special ceremonial gifts.

And now, new research has revealed 70% of the world’s macadamia can be sourced back to a single Australian tree. But all these cloned nuts come with a massive problem.

Nathaniel Keesing spoke with Research Fellow Dr Catherine from the Southern Cross University, about how this nut spread across the world.
