Hobbits In Paradise?So were they or weren't they?
Hobbits, that is...
So hobbits once lived, little three feet high people with skulls the size of grapefruits...But now there is some dispute as to whether that tale, that delighted us all, is scientifically true:
Scientists are to present new evidence that the tiny human species dubbed "The Hobbit" may not be what it seems.
The researchers say their findings strongly support an idea that the 1m- (3ft-) tall female skeleton from Indonesia is a diseased modern human....
[I]t was not long before some scientists began to ask serious questions about the discovery team's conclusions.
Indonesian anthropologist Teuku Jacob controversially took possession of the remains and declared them to be those of a modern human with the condition microcephaly.
This disorder is characterised by a small brain, but it can also be associated with dwarfism, as well as abnormalities of the face and jaw. For this reason, some scientists believe the condition could cause a modern human to look primitive in evolutionary terms.
Jacob was soon joined by a handful of researchers in the belief that the discovery team had happened upon nothing more than a member of our own species with a rare disease.
Professor Bob Martin, one of the team that is set to publish new evidence challenging the discovery team's original interpretation, says the Hobbit's brain is "worryingly" small and contradicts a fundamental law of biology.
"What this law says in simple terms is that if you halve body size, brain size is only reduced by 15%," he told the BBC's Horizon programme.
"So if you halve body size you don't halve brain size, the brain is reduced far less than that."...
But there's a problem with the sceptics' version of the story. The Hobbit team has found more human remains. These include a lower jaw with the same unusual features as the original find (including twin roots to the molars).
"Let's buy into [the sceptics'] argument just for a bit of fun," said Professor Bert Roberts of the University of Wollongong, Australia, a member of the discovery team.
"We've got a complete lower jaw that's identical to the first so there we have a situation where we've now got to have two really badly diseased individuals.
"We've got a diseased population like some sort of leper colony, living in Liang Bua 18,000 years ago. The probabilities have got to be vanishingly small."
