Fiery re-creations show how Neandertals could have easily made tar
Burning sticky goo may not have required the mastery of fire
NEANDER-TAR Using a simple experimental technique, researchers collected tar in a birch-bark vessel. This method, which could have been used by Neandertals as early as 200,000 years ago, consists of placing embers from a fire over a roll of burning birch bark positioned upright in a small pit.
