Potts notes that while the study is exciting, it also raises a lot of big questions. … The Earth is some 4.5 billion years old with humanity taking up not more than 200,000 years. With new environments came new food sources and a need for tools to process those foods. Earth S Oldest Rocks Were Likely Formed In The Crucible Of A. Scars cut into the stones set them apart from run-of-the-mill rocks. Cookie Policy The common assumption has been that as Africa’s climate changed and forest canopies gave way to savannas, early hominins diversified and the Homo genus—the line that would produce modern humans—emerged, around 2.8 million years ago. The stemmed points were extremely similar to a type found in Hokkaido, Japan, also dated to around 16,000 years old. “That's a different but equally interesting story, in which our genus evolved half a million years before, and in response to completely different natural selective pressures, than we currently think,” says Lewis. In a talk at the annual meeting of the Paleoanthropology Society here, archaeologist Sonia Harmand of Stony Brook University in New York described the discovery of numerous tools at the site of Lomekwi 3, just west of Lake Turkana in Kenya, about 1000 kilometers from Olduvai Gorge.

Although very recent research has now pushed back the origins of the genus Homo to as early as 2.8 million years ago, the tools are too old to have been made by the first fully fledged humans, Harmand said in her talk. That’s 700,000 years older than the oldest-known tools to date, suggesting that our ancestors were crafting tools several hundred thousand years before our genus Homo arrived on the scene. “I've seen the altered rocks, and there is definitely purposeful modification of the stones by the hominins at the Lomekwi site 3.3 million years ago,” says paleoanthropologist Rick Potts, director of the Smithsonian’s Human Origins Program, who was not affiliated with the study. The stone tools were found near the oldest fossil attributed to the genus Homo. And the oldest tools were neatly sandwiched between rocks that formed between two flips of the magnetic field: one 2.14 million years ago, and a second about 1.85 million years ago. She's previously written for NPR, National Geographic News, Nature and others. The wheel dates back around 5,300 years, but could possibly be even older.

Archaeologists have uncovered about 20 different artifacts from Lomekwi, including anvils, cores, and flakes. If correct, the new evidence could confirm disputed claims for very early tool use, and it suggests that ancient australopithecines like the famed “Lucy” may have fashioned stone tools, too. 17th Annual Photo Contest Finalists Announced.

The oldest geological material ever found, which are not technically rocks, are mineral grains called zircons found in Western Australia, which date back about 4.36 billion years. “To us it was immediately a very interesting area,” notes Harmand, “with outcrops and erosive cuts, you could see what was normally hidden by the sediment.” So, they spread out and started looking.

When you think about the oldest settlements and cities on Earth, a few of us are aware of the fact that some of these cities date back to times before history was even written. Dating of the sediments using paleomagnetic techniques—which track reversals in Earth’s magnetic field over time and have been used on many hominin finds from the well-studied Lake Turkana area—put them at about 3.3 million years old. Another hominin, Australopithecus africanus, appears to have had a grip strong enough for tool use. The earliest time that life forms first appeared on Earth is unknown. They took a wrong turn and stumbled upon another part of the area, called Lomekwi, near where Kenyanthropus had been found. The Lomekwi tools were somewhat larger than the average Oldowan artifacts, however. “This discovery challenges the idea that the main characters that make us human—making stone tools, eating more meat, maybe using language—all evolved at once in a punctuated way, near the origins of the genus Homo,” says Jason Lewis, a paleoanthropologist at Rutgers University and co-author of the study.
