"The World's Oldest Stone
Tools"
In 2011, Dr Harmand and her
team unearthed the earliest stone tools ever found dated at 3.3
million years old, which predates the previous record by 700,000
years. The artifacts were found at the archaeological site
Lomekwi 3 on the western shore of Lake Turkana in northern
Kenya. They show that at least one group of ancient hominins
started intentionally knapping stones to make sharp tools long
before previously thought. These tools published in the journal
Nature in 2015 shed light on an unexpected and previously
unknown period of hominin behavior, and can tell us a lot about
cognitive development in our ancestors that we can’t understand
from fossils alone. Though it’s unclear who made the tools, this
finding disproves the long-standing assumption that Homo habilis
was the first tool-maker. Tool-making began before any members
of the Homo genus walked the Earth.
About the Speaker:
Dr. Harmand is an Associate Professor in Anthropology at The
State University of New York at Stony Brook and co-Director of
the West Turkana Archaeological Project. Dr. Harmand is an
expert in Early Stone Age archaeology. Her research program
revolves around the central theme of how, when and why did stone
tool manufacture and use originate among hominins. Since 1998,
she has focused her research on reconstructing the genesis of
hominin technology, a period for which the archaeological record
is meager. In 2011, her annual field expedition in northern
Kenya yielded the earliest archaeological site known, dated at
3.3 million years. In addition, Prof. Harmand, along with her
team, is exploring the biomechanics involved in the making and
possible use of stone tools. She is also currently collaborating
with primate archaeologists. Prof. Harmand worked as a Research
Scientist at the Centre National de la Recherche Scientifique
(CNRS) in France from 2009 to 2012.
