Although bearing a long tail, Ida had several characteristics shared by humans such as an opposable thumb, relatively short arms and legs, and forward facing eyes

NEW YORK: Scientists in New York have unveiled the skeleton of what they said could be a common ancestor to humans, apes and other primates.
The tiny creature, officially Darwinius masillae, but dubbed Ida, lived 47 million years ago and is 95% complete, missing only part of a leg. Incredibly, the lemur-like fossil also features the complete soft body outline, right down to the fur, as well as the gut contents.
"The link they would have said until now is missing... it is no longer missing," said David Attenborough, renowned British naturalist and broadcaster. "This little creature is going to show us our connection with all the rest of the mammals."
"In all the textbooks"
The finding, described Tuesday in the journal PloS One, was also displayed at a press conference at New York City's Natural History Museum, and is due to be the subject of a documentary on the History Channel, BBC and other broadcasters.
Scientists led by Norwegian fossil hunter Jørn Hurum, of the University of Oslo, worked secretly for two years on a detailed forensic analysis of Ida. She was first dug up in 1983 by private collectors who failed to understand her importance – and split the bones into two lots, which have now been reunited.
"This fossil is so complete. Everything's there. It's unheard of in the primate record at all. You have to get to human burial to see something that's this complete," said Hurum. "This fossil will probably be pictured in all the textbooks for the next 100 years."
With similarities to both monkeys and lemurs, which are more primitive primates, the creature was preserved through the ages in Germany's Messel Pit, which is rich in Eocene Epoch fossils. Features of the bones revealed that the fossil was a female that died at a young age.
Long lost aunt
Although bearing a long tail, she had several characteristics shared by humans such as an opposable thumb, relatively short arms and legs, and forward facing eyes. She also lacked two key elements of modern lemurs: a grooming claw and a row of lower teeth known as the toothcomb.
"It's really a kind of Rosetta Stone," commented palaeontologist Philip Gingerich of the University of Michigan, referring to the mixture of primitive and modern features.
Study co-author Jens Franzen, said we should think of Ida more as a distant aunt to the human family tree rather than a direct distant ancestor.
At Last
Brilliant; very, very exciting. I have been waiting for this a long time, of course there is there was so much we will never find; but we now do have Ida. I'm glad about the media hype; about time this kind of find was seen as significant. The 'hobbits' and other homo finds are very interesting, and no doubt there will be more, but this is far more important; my idea of the missing link too.
missing link???
We should have known the forerunner of humanity was going to be a type of rat!
"Ratman"
What a load of rubbish. Talk about grasping at any opportunity to expose macro evolutionary theory. A lot a animals have "human" characteristics". Cats have forward facing eye's, frogs have over 90% human DNA etc etc. These scientists should really sit down and have a good look at the "evidence" and try and interpret it in a truly unbiased way. Don't always put it in a evolutionary frame, is there something else? Don't always follow the established dogma of evolution. Where did the new DNA information come from to make this creature evolve into something else?
Looks like the distant cousin of a rat to me! Rats are rats and always will be...
