A cache of 1.5 million-year-old bone tools uncovered in Tanzania suggest ancient human ancestors were capable of critical thinking and advanced craftsmanship.

New evidence uncovered in east Africa indicates ancient hominins began crafting tools from animal bones far earlier than previously thought. If confirmed, our human ancestors started shaping bones by striking them at specific angles in a process known as knapping as much as 1.5 million years ago.

The oldest human-crafted bone tools on record are 1.5 million years old, a finding that suggests our ancestors were much smarter than previously thought, a new study reports. The tools, made from hippo and elephant leg bones, were discovered at Olduvai Gorge in Tanzania and are a million years older than any previously found shaped bone tools.

A recent discovery in Tanzania’s Olduvai Gorge has revealed that early humans were crafting bone tools 1.5 million years ago, pushing back previous estimates by a million years. Researchers found 27 well-preserved bone tools,

The handcrafted tools found in Tanzania were made 1.5 million years ago and were fashioned primarily from the bones of elephants and hippopotamuses.

A group of scientists have discovered some 27 bone tools made some 1.5 million years ago by ancient humans in Olduvai Gorge in Tanzania, East Africa.

Early hominids were systematically producing bone tools at least one million years sooner than archaeologists previously believed, according to a new study published in Nature. Researchers from the CSIC-Spanish National Research Council unearthed an ancient bone toolkit in Tanzania’s Olduvai Gorge that dates back 1.
