"These dates do not stand up to close scrutiny," says Witwatersrand paleoanthropologist Lee Berger. It also means that "hominids were basically all over Africa 4 million years ago," says paleontologist Fred Spoor of University College London. ![]() If that's correct, then Little Foot's contemporary was Australopithecus anamensis, who lived 4 million years ago in east Africa. Granger dated samples of the cementlike matrix of rock and sand surrounding Little Foot to 4.17 million years ago, plus or minus about 350,000 years. Geologist Tim Partridge of the University of the Witwatersrand in Johannesburg, South Africa, sent Granger five samples of a fossil known as Little Foot from the Sterkfontein Caves. The older the rock, the more isotopes it accumulates when it is buried, the bombardment stops and the isotopes decay (Science, 11 January 2002, p. When cosmic rays bombard Earth's surface, they collide with the nuclei of atoms such as oxygen, producing unstable isotopes of beryllium and aluminum. The new estimates, reported in the 25 April issue of Science, are based on a technique developed by Darryl Granger, a geologist at Purdue University in West Lafayette, Indiana. Using a new dating method, researchers now suggest that hominid remains from the Sterkfontein caves are a stunningly ancient 4 million years old.Īge estimates for Sterkfontein's 500 hominid fossils have ranged widely, from 3.5 million to 1.5 million years old. Far from being natural caverns in rock like most caves, however, the ones in Guadix were actually chiselled out of the earth.Certain limestone caves in South Africa have been called the cradle of humankind because they contain nearly one-third of known early human fossils. When they arrived and had nowhere to live, many of the Moriscos (Moors who had been forced to become Christian) decided to build their homes underground, primarily to escape the heat. More people fled here from 1568 to 1571 during the Rebellion (or War of the Alpujarras). When the Catholic monarchs regained control of Andalucía and took Granada in 1492, many of the Moors were displaced and fled to the surrounding mountains and the town of Guadix. Some of the oldest caves are believed to have been built during the early period of their rule, and date back around 1,000 years, although most were built during the 15th and 16th Centuries.ĭuring the Moorish time, Guadix was an important trade town, as it was midway between the city of Granada, the stronghold of the Alhambra Palace, and the sea. It was later taken over by the Moors when they ruled Andalucía from around the 8th to the 15th Centuries, building the Guadix Alcazaba, the magnificent Moorish fortress I had seen from José’s terrace, around the 11th Century. The main town, however, was founded by the Romans to mine the silver found in the nearby hills. It seemed comfortable enough, but I couldn’t help but wonder what it would actually be like to live in a cave.Īfter thanking José for his hospitality, I headed towards the Cave Interpretation Centre, where I learned that the area where Guadix stands today is one of Europe’s oldest settlements, dating back to the Stone Age. The room he seemed most proud of though was his bathroom, which was small with a built-in shower. Flamenco is still a very important part of our culture here, like it is in many parts of Andalucía.” He showed me his bedroom, which held a large gold bed, religious paintings on the walls and a frilly red flamenco dress hanging in one corner. “Come, come,” José said as he motioned for me to go further inside. I was surprised at how large and spacious it all was. José then showed me into a large dining room, where a long wooden table was covered with bowls of dried fruit and vegetables, and the walls were decorated with religious icons and other cultural trinkets. The terracotta farm-style kitchen was modern yet rustic, with dried red peppers, onions and garlic hanging from the ceilings and walls. He proudly led me around his home, showing off his various rooms and possessions.
