Researchers believe plaque they found on 400,000-year old teeth
reveals a lot about the diet and food preparation methods of early
Paleolithic humans.
Traces of charcoal found on the teeth suggested that the inhabitants
of Qesem Cave near Tel Aviv feasted on meat roasted on indoor fires,
scientists from Tel Aviv University said Wednesday. The pollution they
then inhaled had a negative impact on their health, evidence of which
survived to this day.
