Not even a monkey's uncle: Analysis calls fossil primate only a distant relative of apes, us Module body
By Malcolm Ritter, The Associated Press

Remember Ida, the fossil discovery announced last May with its own book and TV documentary? A publicity blitz called it "the link" that would reveal the earliest evolutionary roots of monkeys, apes and humans.
Experts protested that Ida wasn't even a close relative. And now a new analysis supports their reaction.
In fact, Ida is as far removed from the monkey-ape-human ancestry as a primate could be, says Erik Seiffert of Stony Brook University in New York.
He and his colleagues compared 360 specific anatomical features of 117 living and extinct primate species to draw up a family tree. They report the results in Thursday's issue of the journal Nature.
Ida is a skeleton of a 47 million-year-old cat-sized creature found in Germany. It starred in a book, "The Link: Uncovering Our Earliest Ancestor."
Ida represents a previously unknown primate species called Darwinius. The scientists who formally announced the finding said they weren't claiming Darwinius was a direct ancestor of monkeys, apes and humans. But they did argue that it belongs in the same major evolutionary grouping, and that it showed what an actual ancestor of that era might have looked like.
The new analysis says Darwinius does not belong in the same primate category as monkeys, apes and humans. Instead, the analysis concluded, it falls into the other major grouping, which includes lemurs.
Experts agreed.
"This is a rigorous analysis based on many features," said Eric Sargis, an anthropology professor at Yale. He said he'd found the argument of the Darwinius researchers unconvincing, so the new result came as no surprise.
In fact, it confirms what most scientists think, said David Begun, a paleoanthropologist at the University of Toronto.
Jorn Hurum of the Natural History Museum in Oslo, Norway, an author of the Ida paper, said he welcomed the new analysis.
Darwinius is an example of a group of primates called adapoids, and "we are happy to start the scientific discussion" about what Ida means for where adapoids fit on the primate family tree, he wrote in an email.

At first, they thought the fossil was a primitive member of the Haplorrhini (Tarsiers, New World Monkeys, Old World Monkeys/Apes), but more scientists now say it is in fact a member of Strepsirrhini (Bush Babies, Lorises, Lemurs). The Strepsirhini are the more "primitive" or "archaic" form of primates. Often scientists make conclusions too quickly before doing more study. I think the jury is still out on Homo floresiensis. Is it a different species or was it a human with a disease?
