Some 12,000 years ago, the only place to live along the eastern Sahara Desert was the Nile Valley. Being so crowded, prime real estate in the Nile Valley was difficult to come by. Disputes over land were often settled with the fist, as evidenced by the cemetery of Jebel Sahaba where many of the buried individuals had died a violent death.
But around 10,500 years ago, a sudden burst of monsoon rains over the vast desert transformed the region into habitable land.
This opened the door for humans to move into the area, as evidenced by the researcher's 500 new radiocarbon dates of human and animal remains from more than 150 excavation sites.
"The climate change at [10,500 years ago] which turned most of the [3.8 million square mile] large Sahara into a savannah-type environment happened within a few hundred years only, certainly within less than 500 years," said study team member Stefan Kroepelin of the University of Cologne in Germany.
The cradle of humanity lies south of the Sahara, which begs the question as to how our species made its way past it. The Sahara is the largest hot desert in the world, and would seem a major barrier for any humans striving to migrate off the continent.
Scientists have often focused on the Nile Valley as the corridor by which humans left Africa. However, considerable research efforts have failed to uncover evidence for its consistent use by people leaving the continent, and precisely how watery it has been over time is controversial.
Now it turns out the Sahara might not have been quite as impassable as once thought — not only for humanity, but for fish as well.
Neanderthals, or even older Homo erectus("Upright Man") might have sailed around the Mediterranean, stopping at islands such as Crete and Cyprus, new evidence suggests. The evidence suggests that these hominid species had considerable seafaring and cognitive skills.
"They had to have had boats of some sort; unlikely they swam," said Alan Simmons, lead author of a study about the find in this week's Science. "Many of the islands had no land-bridges, thus they must have had the cognitive ability to both build boats and know how to navigate them."
Faces of our Ancestors
Simmons, a professor of anthropology at the University of Nevada, added that there is no direct evidence for boats dating back to over 100,000 years ago. If they were built then, the wood or other natural materials likely eroded. Instead, other clues hint that modern humans may not have been the first to set foot on Mediterranean islands.
On Crete, for example, tools such as quartz hand-axes, picks and cleavers are associated with deposits that may date to 170,000 years ago. Previously, this island, as well as Cyprus, was thought to have first been colonized about 9,000 years ago by late Neolithic agriculturalists with domesticated resources.
I guess the only real way to find out is to simply start digging...

What I don't understand is why it takes decades to unearth a village. I understand trying to preserve history and all, but if an institution finds a archaeological site, it seems to take years to unearth it since they seem to just pick at it for years.
And all the while, what was once protected by the elements is now exposed for years as they continue to dig.
Yea, I know, it's expensive as well.

Just my opinion Slayer, but I think there are some massive and surreal surprises waiting to be unearthed in places like this, as well as underwater. Finds that will completely rewrite what we think we know about this planets history. But sometimes, I get the impression they don't really want to know.

Sites excavated prior to the establishment of archaeological practices did destroy lots of stuff. Archaeology by its nature is destructive of all sites. Such expeditions were more looting digs than scientific but they have to be judged in the context of their times. At one time the 'Indiana Jones or bulldozer/dynamite' excavation was all the rage.

Too right there Can't blame them, even in recent history 'restorers' used Concrete to repair/complete the stone work. Having no idea that once that concrete breaks away it takes half the stone with it. Much like a filling can do to a tooth. There is probally loads of methods we use today that in 50 or so years would be deemed detremental to site preservation.

IF there are sites revealed 'They' will have no choice but to reexamine their perspective, Just like how Göbekli Tepe made some switch gears.
