By all scientific accounts, the rounded objects with even latitudinal grooves are 3 billion-year-old rocks that were naturally formed by carbonate concretions. Over the process of their development the tiny pyrophyllite spheres, which range in size from .5-10 cm, were created when minerals formed in the space between sediments. Weathering of these specimen left them as tiny balls, with evenly spaced lines circumscribing them.

Of course, this answer does not exactly satisfy those who believe the spheres are too perfect to have been created naturally, and since their first discovery in South African mines, they have been linked to intelligent beings from a different place or time.

A 65-meter high minaret stands in Afghanistan, built around 1190 CE. It is covered with religious carvings and calligraphy in more than one language. But this ancient and remote edifice is surrounded by the Hindu Kush mountains in a country at war, so these pictures will be the closest you get to it -for now.

Amazingly, this imposing structure was standing forgotten for centuries… until rediscovered in 1886 by Sir Thomas Holdich; then forgotten again and rediscovered in 1957. Then the Soviet invasion in 1979 again prohibited access to the area, and since then only a handful of people from outside of Afghanistan have seen the minaret, because of its middle-of-nowhere location

Archaeologists have announced the discovery of the world’s oldest winemaking facility. The winery was found in an Armenian cave near the village of Areni -the same cave where the oldest shoe ever was found last year. Carbon dating shows that the winery dates back 6,100 years!

In September 2010 archaeologists completed excavations of a large, 2-foot-deep (60-centimeter-deep) vat buried next to a shallow, 3.5-foot-long (1-meter-long) basin made of hard-packed clay with elevated edges.

The installation suggests the Copper Age vintners pressed their wine the old-fashioned way, using their feet, Areshian said.

Juice from the trampled grapes drained into the vat, where it was left to ferment, he explained.

The wine was then stored in jars—the cool, dry conditions of the cave would have made a perfect wine cellar, according to Areshian, who co-authored the new study, published Tuesday in the Journal of Archaeological Science.

Analysis of residue found malvidin, a plant pigment found in red wine. Read more about the discovery at National Geographic News. Link -Thanks, Marilyn Terrell!

Knapped from a cobble of local quartz stone, the rough-looking tool resembled hand axes discovered in Africa and mainland Europe and used by human ancestors until about 175,000 years ago. This stone tool technology, which could have been useful for smashing bones and cutting flesh, had been relatively static for over a million years.

Crete has been surrounded by vast stretches of sea for some five million years. The discovery of the hand ax suggests that people besides technologically modern humans—possibly Homo heidelbergensis—island-hopped across the Mediterranean tens of thousands of millennia earlier than expected.

More digging unearthed a total of 30 hand axes plus other tools at nine locations on Crete. The rock terraces the tools were taken from are thought to range from 45,000 years old to 130,000 years old.

“I was flabbergasted,” said Boston University archaeologist and stone-tool expert Curtis Runnels. “The idea of finding tools from this very early time period on Crete was about as believable as finding an iPod in King Tut’s tomb.”

It was thought that humans earlier than Homo sapiens were incapable of long deliberate sea voyages. Link

A few days ago, you read about Clonehenges, art installations that are made to resemble the original Stonehenge. You might not realize that Stonehenge is far from the only ancient stone circle in the UK, and there are some in Europe and North America as well. WebEcoist looks at 13 of these circles, including the pictured Avebury Stone Circle in England, which is bigger and older than Stonehenge! Link

Believe it or not, explorers believed California was an island for a very long time and this map depicts that assumption. It would take over 50 years after the creation of this map before it was confirmed that California is indeed attached to the mainland of America.
