2 . Macaques don’t use the sharp flakes they create for anything, Luncz adds, noting that the monkeys have sharp teeth and don’t need cutting tools. The similar ancient stone tools collected from some of the earliest known sites, however, show evidence of being used for cutting tasks. For example, in Oldowan, a site dating between 3.3 million and 1.5 million years ago, researchers analyzed use-wear patterns on the tools and found that some of the flakes showed damage along their edges, indicating that they had been used for cutting. Cut marks on some fossils revealed that hominins had used stone tools for butchering the animals, making it clear that the sharp stone tools were anything but unintentional by-products of other pounding activities.

6 . Archeologists said on Wednesday they have unearthed the oldest wooden structure ever discovered, dating from nearly half a million years ago, which suggests that our ancestors may have been more advanced than previously thought.
The exceptionally well-preserved wooden structure was found at Kalambo Falls in the north of Zambia near the border with Tanzania. It dates back at least 476,000 years, well before the evolution of Homo sapiens (智人), according to a study describing the find in the journal Nature.
The wood bears cut-marks showing that stone tools were used to join two large logs to make the structure, which is believed to be a platform, walkway or raised dwelling to keep our ancestors above the water. A collection of wooden tools, including a wedge and a digging stick, was also discovered at the site. The ancestors of humans were already known to use wood at this time, but for limited purposes such as starting a fire or hunting.
Larry Barham, an archeologist at the U. K.’s University of Liverpool and the study’s lead author, said the structure was a “chance discovery” made in 2019 while excavating the site located on the banks of the Kalambo River, above a 235-meter waterfall.
Discoveries involving such ancient wood are rare, because it tends to rot leaving behind little trace for the historical record. But the high level of water at Kalambo Falls is believed to have preserved the structure over the centuries.
Excavations at the Kalambo site in the 1950s and 1960s unearthed some wood, but it was not able to be accurately dated. However, this time around, the researchers used a new method called luminescence dating, which determines age by measuring the last time certain minerals were exposed to sufficient heat or sunlight. This revealed that the structure was much older than the researchers had thought, dating back at least 476,000 years.
The discovery of the wooden structure “changed how I thought about these people”, Barham added. “They transformed their surroundings to make life easier, even if it was only by making a platform to sit on by the river to do their daily chores,” he said. “They used their intelligence, imagination and skills to create something they’d never seen before, something that had never previously existed.”
