Human Culture May Date Back 44,000 Years
Date:8/3/2012

arrowheads or tools, directly dated to 40,000 years ago, is the oldest known evidence of the use of beeswax," Backwell said.

Also found at Border Cave were warthog tusks shaped into awls and possibly spearheads. After a chemical analysis of resin residue on certain tools, the researchers also confirmed that small pieces of stone were used to equip hunting weapons.

Although stone tool technology appears to have evolved gradually, other artifacts appeared to emerge unexpectedly. The researchers concluded rates of cultural change are best understood when documented regionally.

The research was published in this week's online issue of the journal Proceedings of the National Academy of Sciences.
