SCIENTISTS in New York today unveiled the skeleton of what they said could be the common ancestor to humans, apes and other primates. The tiny creature, officially known as Darwinius masillae, but dubbed Ida, lived 47 million years ago and is unusually well preserved, missing only part of a leg, or five per cent of the skeleton.
The finding, described today in the PloS ONE scientific journal, was displayed at New York's Natural History Museum, and is due to be the subject of a documentary on the History Channel, BBC and other broadcasters.
Organisers said that scientists led by Norway's fossil expert, professor Jorn Hurum, worked for two years on Ida, first discovered in 1983 by private collectors who failed to understand her importance - and split the bones into two lots.
The monkey-like creature was preserved through the ages in Germany's Messel Pit, a crater rich in Eocene Epoch fossils.
Although bearing a long tail, she had several human characteristics, including an opposable thumb, 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.
"This is the first link to all humans - truly a fossil that links world heritage," Prof Hurum said.
David Attenborough, the renowned British naturalist and broadcaster, said the "little creature is going to show us our connection with all the rest of the mammals".
"The link they would have said until now is missing... it is no longer missing," he said.
Ida gives a glimpse into a time when the world was just taking its present shape. Dinosaurs were extinct, the Himalayas were forming and a huge range of mammals thrived in vast jungles.
According to the international team, Ida had suffered a badly broken wrist and this might have been her undoing. The theory is that while drinking from the Messel lake she was overcome by carbon dioxide fumes and fell in.
"Ida slipped into unconsciousness, was washed into the lake, and sank to the bottom, where the unique conditions preserved her for 47 million years," organisers said.
Her last meal shows she was a herbivore. Gut contents revealed remains of fruits, seeds and leaves.
"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," Prof Hurum said.

looks like a reptile to me, but I am sure atheists will love this one.
