Stone-Age Tribe Say: 'We're Fine. Thank You For Asking'

It seems as though at least one of the stone-age tribes living on the Andaman and Nicobar Islands have survived the Tsunami. It had been feared that the wave wiped out the islanders, but the latest evidence is that they're very much alive and well:

An Indian helicopter dropping food and water over the remote Andaman and Nicobar Islands has been attacked by tribesmen using bows and arrows.

Apparently,

Dozens of tribesmen fired bows and arrows at the helicopter, a traditional warning that outsiders aren't welcome.

Only a BBC reporter could deliver a line that with a straight face … But it gets better:

Officials believe they survived the devastation by using age-old early warning systems.
They might have run to high ground for safety after noticing changes in the behaviour of birds and marine wildlife.
Scientists are examining the possibility to see whether it can be used to predict earth tremors in future.

So, we can forget about all these high-tech early-warning systems, and go back to a more basic 'when birds fly fast and earth-god shake, run up big hill' approach to future disasters.
Of course, this is assuming some brave soul can be found to actually go and ask the tribespeople about their age-old practices. Given the welcome mat they put out for the Indian chopper, we don't envy anyone that gig.
Oh. Wait. We could always send Sting …
