The 2021 year. 2-Million-Year-Old Stone Tools Discovered: How Were Humans Back Then?
The Olduvai Gorge / Oldupai Gorge in Tanzania has always been one of the most important paleoanthropological sites all around the world. It has given such proofs that paves the understanding of early human evolution. It is because many groups of scientists have been finding hundreds of fossilized bones and stone tools in this area which are from millions of years ago. Ewass Oldupa, the western area of the place, is a 28 miles long canyon which is famous for its hominin fossils. This important place has indeed kept up to the expectation and has gifted the scientists some more

In this week’s episode of The Conversation Weekly podcast, two experts explain how melting ice in the far north is bringing more light to the Arctic Ocean and what this means for the species that live there. And we hear from a team of archaeologists on their new research in Tanzania’s Olduvai Gorge that found evidence of just how adaptable early humans were to the changing environment.

In this week’s episode of The Conversation Weekly podcast, two experts explain how melting ice in the far north is bringing more light to the Arctic Ocean and what this means for the species that live there. And we hear from a team of archaeologists on their new research in Tanzania’s Olduvai Gorge that found evidence of just how adaptable early humans were to the changing environment.
Every summer, the sea ice in the Arctic melts – but it’s melting more and more each year. In September 2020, the ice covered 3.74 million square kilometres in the Arctic. That might sound like a lot, but it was actually the second smallest measurement ever – and roughly half of what was measured in 1980. This dramatic loss is because the Arctic is warming two to three times faster than the rest of the planet.
A team of international archaeologists and paleoanthropologists unearthed a big amount of stone tools dating back 2 million years during the Early Pleistocene period in addition to fossilized bones and plant materials. The discovery was made at a site called Ewass Oldupa which is located in the western part of the ancient basin Olduvai Gorge (now called Oldupai) in the northern part of Tanzania.
The stone tools that were found were part of the Oldowan which is the oldest-known stone tool industry that dates back 2.6 million years and were believed to have been created by
Homo habilis although it’s known not for certain. The authors noted that while they haven’t found any remains belonging to
