Danish archaeologists have uncovered a settlement they believe may be over 700,000 years old, making it the oldest organised human community ever found, reported Berlingske Tidende newspaper. Eight dwellings in the desert region of Qatar indicate that an early human species crossed what is now the Red Sea to leave their origins in Africa, according to the scientists.

The 365 million-year-old fossil skull, shoulders, and part of the pelvis of the water-dweller, Ventastega curonica, were found in Latvia, researchers report in a study published in today's issue of the journal Nature. Even though Ventastega is probably an evolutionary dead-end, the finding sheds new details on the evolutionary transition from fish to tetrapods. Tetrapods are animals with four limbs and include such descendants as amphibians, birds, and mammals. While...

The baron, who was a dinosaur buff, identified the bone as belonging to a dwarf dino that likely once lived on an island in the region. The motorcycle-riding baron's outrageous theories were ridiculed and largely dismissed, but now new evidence suggests his proposed island of dwarf dinosaurs did indeed exist in the land of...

The study, which will be published in the August issue of the Journal of Archaeological Science, also describes a previously undocumented disease, called FOS, which was like leprosy and caused skull lesions. Additionally, the researchers found that mercury-containing medicine had been administered to 79 percent of the...

The notorious pirate ship the Whydah, which was captained by Devon-born "Black Sam" Bellamy, sank in heavy storms in the Atlantic off the coast of Massachusetts in April 1717. When the ship went down she was laden heavily with ingots of gold, valuable gem-stones and dozens of tusks of precious ivory. The booty was so vast that each member of the 180-man crew was entitled to 50lb (23kg) of the haul by weight......

Michigan, the remains of the car ferry Ann Arbor 5 and an unnamed barge. The S.S. Michigan is one of MSRA's six most-sought-after shipwrecks and is the subject of a 2004 documentary called, "ICEBOUND! The Ordeal of the S.S. Michigan." The S.S. Michigan sank on March 19, 1885, just four years after her launch. The 30-man crew made it safely to shore after being stranded on the ice for 42 days. MSRA board...

Martin Hickes reports on an expensive obsession. THIS August, a flotilla of American scientists will mount a £175,000 expedition off Flamborough Head in search of a wreck, more than 200 years after it sank. Two US teams will plunge into the North Sea in search of the flagship of a Scottish captain, known to the Brits as little more than a pirate, but to the Americans as a hero of the American Revolution and the "Father of the...

SCHREADLEY This is Carolina Day, the 232nd anniversary of the Battle of Fort Sullivan. If you are not a native of South Carolinian (and possibly even if you are), you likely have never heard of Fort Sullivan and the significance of this day. Most American school children have heard stirring stories of the battles of Concord Bridge and Lexington Green, relatively minor skirmishes fought by the Minutemen of Revolutionary lore. These were fought in April 1775, and at Concord Bridge was fired the "shot heard 'round the world." But it was at an unfinished, palmetto-log fort on Sullivan's Island where the...

Now one of those men is hoping to use DNA evidence to prove it. The other man, Arthur Ben Chitty, a historiographer at the University of the South who died in 2002, spent 40 years amassing anecdotal evidence that Mr. Booth married a Sewanee woman and lived there for a time, said his daughter Em Turner Chitty. And there was...

No, it isn't, and Malik provides good, if not overwhelming, reasons why not. Or this one: "Distinctions between races are arbitrary." No, they aren't. In a famous experiment in 2002, a computer program was able to "blindly" sort genetic data from individuals around the world into five populations that were nearly identical to the traditional races...

We were once called capitalist pigs or similar metaphors used by much of the communist world.

Far to many Black Americans have yet to move beyond the race issue while at the same time (unfortunately) racism is still practiced by just about every group within our borders.

It is one of the five basic requirements incumbent upon all Moslems that they make (if their health will allow it) a pilgrimage to Mecca once in their lives (the other four: recognize that there is no god but Allah, that Mohammed is Allah's prophet, ritually pray five times a day, and give alms to the poor). The founding events of Islam are Mohammed's activities in Mecca and Medina,...

Its lesser known cousin, HIV-2, jumped into humans decades later, from a monkey species that carried the virus for just a couple of hundred years, not the millions of years researchers had assumed, according to other research presented at the meeting. Researchers are trying to pin down the origins of both HIVs to understand how often new human...

A Montreal writer set to publish a book on Inuit oral chronicles from the era of Arctic exploration says she's gathered a "hitherto unreported" account of a British ship wintering in 1850 in the Royal Geographical Society Islands - a significant distance west of the search...
