Evidence of ancient reversals of Earth’s magnetic field in soil at two archaeological sites indicates that hand axes date to 900,000 years ago in one location and to 760,000 years ago in the other, Scott and Gibert report in the Sept. 3 Nature. Until now, most researchers thought that hand axes unearthed at these sites were made between 500,000 and 200,000 years ago.
Other European hand ax sites date to no more than 500,000 years ago. In contrast, hand axes date to roughly 1.7 million years ago in eastern Africa. And age estimates of 1.2 million years and 800,000 years for hand axes from two Israeli sites indicate that this tool-making style spread out of Africa long before the origin of Homo sapiens around 200,000 years ago. Excavations in southern China have also yielded 800,000-year-old hand axes (SN: 3/4/00, p. 148). Fossils from ancient human ancestors have not been found with the Israeli and Chinese artifacts.
Earlier analyses of magnetic reversals in soil at other sites in southern Spain indicate that single-edged stone tools appeared there around 1.3 million years ago, Gibert says (SN: 1/4/97, p. 12). Population movements back and forth between Africa and Europe must have occurred at that time, possibly via vessels across the Strait of Gibraltar, he hypothesizes.
“Then at 900,000 years ago, we now have the oldest evidence of hand axes in Europe, which represents a second migration from Africa that brought a new stone-tool culture,” Gibert says.
These data provide minimum ages for the Spanish finds. “Older ages are possible but would be odd,” Gibert says.

yeh this blows 7000 years since adam right out of the water.
id be more inclined to listen to creationists if they could accept dating methods and not literally try to guess teh age of the earth based on books written by men in the last 4000 years.

More proof we are much older than we are usually led to believe.
This is fascinating stuff.
900,000!
The last sentence was also revealing...

Why would it be odd to have dates go beyond 900,000 years? Would it really shake things up?

America's first professional Egyptologist, Breasted...
The way Breasted told his bewildered mother of this decision is worth repeating. He stood before her, according to Charles Breasted, and read a passage from the King James version of the Bible. He paused, then read his own translation of the verse from the original Hebrew. The two were markedly dissimilar. To Breasted, if not to his mother, the conclusion was obvious: "I could never be satisfied to preach on the basis of texts I know to be full of mistranslation." www.saudiaramcoworld.com...
