Ancient Jawbone Could Shake Up Fossil Record [ Australopithecus anamensis ]
National Geographic News ^ | Friday the 13th, July 2007 | Nick Wadhams

Jawbones from an early human ancestor, found recently in northeast Ethiopia, could shine light on a murky period of human evolution, paleontologists say. The bones were found in the fossil-rich Afar region, just 20 miles (32 kilometers) north of the spot where the famed skeleton of "Lucy" -- early human ancestor who lived 3.2 million years ago -- was unearthed in 1974... The new bones are believed to date from 3.8 million to 3.5 million years ago. Though more research needs to be done, the group says the bones could bridge the gap between two known human ancestor species. Australopithecus anamensis lived some 4.2 million to 3.9 million years ago, and Australopithecus afarensis -- the species to which Lucy belonged -- thrived from 3.6 million to 3 million years ago... Some researchers believe that Lucy and others of her species were descendants of A. anamensis -- and these new Ethiopian jawbones could end that speculation... "We have had isolated teeth and [other skeleton parts] from previous years. What we didn't have was a complete jaw, which we have now," he said... The earlier species, A. anamensis, had large canine teeth and a narrow jaw. When Lucy appeared, compared to A. anamensis, the jaw had widened, the canines had become smaller, and the molars had grown. Such changes suggest that the A. afarensis chewed, not tore, its food.

;’) Maybe, but probably the wrong hemisphere (and era) for that. ;’)

They were straight, and nearly parallel. Dog-like. (my son’s pit bull has jaws very similar to the picture, with almost the same angle)

Perhaps a Nancy Pelosi link?

That is a pretty picture made by speculation.

Science only deals with the hear and now. It can only speculate about the past and only make assumptions of the future.

The article is filled with assumptions.

Or was that a date on the jaw bone I saw.

Dating methods only fulfill evolutionary needs, they are all that is all speculative, assumptive, and indecisive.

If you have a specific problem with my post, please state it.

Otherwise, your post is generic, unsupported anti-science nonsense.

About all I can glean from your post is that you don't like "dating methods." Please examine the links below and let me know what you would like help on.

Coyoteman,

Your dating methods are all speculative.

Deny that you assume the sample to be pure in nature and the product you are interpreting is the product of decay.

Deny that when you find a rock in a certain strata that you expect a date based upon the fossil content of that strata.

Deny that you Coyoteman date every sample with a presupposition of older than 6000 years when it pertains to evolution or age of earth.

Hear and now? or hear and see?

When you have learned as much about dating as I have, then you can lecture me.

Check the dating links on my FR homepage for a start.
