This is a very contentious topic among many archaeologists. Definitely worth checking out the program, and also click on the 'Resource Section' of the link above. It has a bunch of links to sites dealing with 'first American' topics.
Here's a story on one of the sites in the program: ‘Scientific American’ shines spotlight on S.C. dig
More tombs! 50 ancient tombs uncovered
ARCHEOLOGISTS have discovered 50 tombs dating back to the late Minoan period, around 1400 BC, and containing a number of artifacts on the Greek island of Crete, ANA news agency reported today.
The tombs were part of the once powerful ancient city of Kydonia, which was destroyed at the time but later rebuilt.
The oldest among them contained bronze weapons, jewellery and vases and are similar to the tombs of fallen soldiers of the Mycenaean type from mainland Greece, said the head of the excavations, Maria Vlazaki.
The more recent family tombs are of a more traditional Kydonia type.
Earlier excavations in the area in northwest Crete near the town of Chania had already yielded some 100 burial sites.
Now, this is cool Hi-tech Scots stand guard over herald of the gods
A TEAM of Scottish experts have used the latest computer technology to protect a priceless 2300-year-old Greek statue.
Hermes of Praxiteles, the sole surviving work of one of classical Greece's finest sculptors, was threatened by earthquakes as it stood in the country's most important archaeological museum in Olympia, the birthplace of the Olympic games.
However, pioneering work by computer experts from Glasgow, which involved scanning the statue, creating 3D models and pinpointing break lines, will now safeguard it from potentially catastrophic seismic activity.
Hard to read, but interesting.
Prehistoric Chinese Colonial Williamsburg Primeval village restored at ancient culture site
A prehistoric village has been restored at a Hongshan culture site in Chifeng City, north China's Inner Mongolia Autonomous Region, enabling visitors to learn about the life of Chinese forefathers at least 5,500 years ago.
The village, covering more than six hectares of land in Hongshan Forest Park, comprises six old-style houses and a fish pond. The exhibit also includes dozens of sculptures of scenes from daily prehistoric life, including fishing, hunting and production of stone and chinaware implements.
Sources with the Chifeng municipal government said the restoration of the village aims to commemorate the 50th anniversary of the naming of the Neolithic Hongshan culture which dated back 5,500 to 6,000 years.
Really old mud bricks Pre-Harappan bricks found in Gulf of Cambay
In an underwater exploration in the Gulf of Cambay, National Institute of Ocean Technology (NIOT) scientists discovered almost 9,500-year-old bricks made of clay and straw.
Archaeological experts of the MS University who, too, are involved in a part of the exploration near Surat and the coast of Gulf of Cambay, however, feel that a further insight into the size of the bricks can confirm its age and its period.
The bricks, believed to be pre-Harappan, have been identified to be of the Holocene age.
Seems like an awful old set of mud bricks. File this one under "Let's wait and see".

Bloody stone tools tell hominids' tales
Two million-year-old blood and fat on stone tools found in South Africa are giving clues about what hominids ate and how they lived, says an Australian researcher.
Molecular archaeologist, Dr Tom Loy of the University of Queensland, reported his analysis of biological residues found on quartz stone tools at a recent ancient biomolecules conference in Brisbane.
"I looked at them and there was blood everywhere," Loy said of the tools, which are among the oldest of their kind, and came from the Sterkfontein caves 60 kilometres northwest of Johannesburg.
Loy found intact and fragmented red and white blood cells; fat cells from bone marrow; collagen from ligaments and tendons; muscle tissue and even degraded hair on the tools.
This technique has been around for a while in one form or other, and has been used in several contexts. Perhaps most notably in two issues in North American archaeology: hunting among the Clovis and cannibalism in the southwest. The former is restricted to stone tools (generally projectile points and such) and the latter focuses on ceramics.
Blood residue analysis has been used to determine what animals were actually hunted by prehistoric people which has been important in linking humans to possible megafaunal extinctions. See this online Archaeological Report that uses blood residue on a Clovis site in Washington state (scroll down for "East Wenatchee Clovis Site" by Richard Michael Gramly).
There are several reports online regarding the cannibalism story; start here.
