When Is a Primate a Human Ancestor?
May 14, 2007
Behold Aegyptopithecus zeuxis, an extinct fossil monkey.  It had a brain smaller than a lemon, smaller than that of modern lemurs.  Why, then, are the news media touting this as a human ancestor?     The new specimen of Aegyptopithecus is more intact and complete than previous specimens.  Two surprises were noted; the amount of […]

Passings: Howell Dies, of Time-Life Book Fame
May 3, 2007
Nature contained an obituary for F. Clark Howell, paleoanthropologist (1925-2007).  He knew and worked with most of the 20th century fossil-man hunters from Raymond Dart to the Leakeys.  Students will probably remember the Time-Life series he authored, Early Man, with its fold-out panorama by illustrator Jay Matternes of the march from furry monkey to naked […]

Cave Chimps Suggest Cave Men
April 11, 2007
Some chimpanzees have been found in Senegal using caves for shelter from the heat.  Jill Pruetz (Iowa State) took note of this and is publishing a paper about it in Primates.  National Geographic speculated that this sheds light on human origins: The adaptations of savanna chimpanzees are particularly interesting to researchers because early humans are […]

Lucy the Gorilla?
April 10, 2007
Three scientists from Tel Aviv found a “gorilla-like” jaw structure on a recently discovered specimen of Australopithecus afarensis, of which “Lucy” is the best-known example.  This is a problem, because Lucy was supposed to be transitional between chimpanzees and humans, not gorillas.     Publishing in PNAS,1 they said, “The presence of the morphology in […]

Earliest Comb Jelly Fossil Looks Modern
April 3, 2007
One would think that a paper listed in the category “Evolution” would include supporting evidence that evolution had occurred, but a new Evolution paper in PNAS provides more arguments against it than for it.1  An international team studying early Cambrian fossil beds in China found a comb jelly embryo essentially identical to those alive today.  […]

Chinese Claim Early Man Fame
April 3, 2007
The “out of Africa” hypothesis must be wrong, some Chinese anthropologists claim, because they have a modern skeleton 40,000 years old.  The story is reported by the BBC News, EurekAlert, National Geographic News and Science Daily.     The BBC News report starts, “The find could shed light on how our ancestors colonised the East, […]

Did Indians See Jurassic Beasts?
March 30, 2007
Did Indians have familiarity with Jurassic monsters, or were they good paleontologists, skilled at reconstructions?  In the “Random Samples” page of news tidbits in the journal Science March 30,1 the story is told and the interpretation given: Some fossils are rare, but this one recently unearthed in eastern Oregon may be positively mythic.  In life, […]

New Dinos Found; What Do They Mean?
March 27, 2007
There is often a wide gap between the bones that are found and the stories that are told about them.  As new dinosaur bones come to light, some reporters cannot resist imagining all kinds of things about their lifestyles.  Here are two recent examples.  As a bonus, we’ll add a non-dinosaur reptile story or two.

Leakey Manipulated His Apelike “Skull 1470” to Look Human
March 27, 2007
The skull of an alleged human ancestor Richard Leakey made famous in 1972 was poorly reconstructed, claims a paleoanthropologist who specializes in craniofacial biology.  According to Dr. Timothy Bromage of New York University, Leakey employed nonstandard principles while assembling the bones of his “Skull 1470”, giving the face a flatter, more human-like profile.  Many at […]

Missing Link, or Just Jawboning About Ear Evolution?
March 19, 2007
Tetrapod vertebrates (four-footed animals with backbones) comprise a dizzying array of species, both living and extinct.  When is it justifiable to arrange different forms into an ancestral evolutionary sequence, especially when some members are extinct and others are still alive today?  On what basis can scientists claim that a discovery demonstrates evolution?  Some Chinese scientists […]
