A new study of artifacts found in a cave in Israel suggests that human
beings began using fire at will around 350,000 years ago, with earlier uses
likely more opportunistic than controlled.

Learning
how to make fire at will is an accomplishment for ancient humans paramount to
sending a man to the moon in modern times. However, up to now, no particular
consensus has been reached regarding exactly when early humans gained control
over fire and the ability to start fires when they needed to. A new study
published this week in the Journal of Human Evolution suggests that
early humans learned to use fire at will about 350,000 years ago.
This new
information challenges some standard notions, including that the control of
fire was necessary to facilitate the development of bigger brains as well as
the migration of hominids into colder climates. The discovery of evidence for
fire control at 350,000 years has the implication that larger brains and
migrations to colder regions of the planet both happened before humans acquired
a mastery of fire.
The team
of researchers, led by Ron Shimelmitz, an archaeologist at the University of
Haifa in Israel, analyzed artifacts collected earlier from sedimentary layers
in the floor of the Tabun Cave located about 24 kilometers south of Haifa.
Specifically, Shimelmitz and colleagues examined flints for evidence of burning
or scorching at various levels of the cave’s sediment layers.
The Tabun
Cave, which was declared highly important by UNESCO a couple years ago, has
well-dated layers of sediment that are thought to cover some 500,000 years of
human history. The researchers found a sudden appearance of burned flints at
around 350,000 years ago and more recently but very few older than this.
The
authors of the report reasoned that since wildfires rarely occur in caves, the
appearance of burnt tools likely indicates the development of controlled fire
use. Hominids probably used fire before this time in a more opportunistic
fashion, they suggest.
