Congratulations to Liora Horwitz and colleagues on PNAS article on the earliest known fire!

Congratulations to Liora Horwitz, project zooarchaeologist, for the publication of a groundbreaking study on evidence of the earliest known intentional fire associated with human activity.
The article is entitled:
Berna, F., Goldberg, P., Horwitz, L. K., Brink, J., Holt, S., Bamford, M., and and Chazan, M. 2012. Microstratigraphic Evidence of in Situ Fire in the Acheulean Strata of Wonderwerk Cave, Northern Cape Province, South Africa. Proceedings of the National Academy of Sciences 109 (doi: 10.1073/pnas.1117620109)

Here is the abstract of the article:
The ability to control fire was a crucial turning point in human evolution, but the question when hominins first developed this ability still remains. Here we show that micromorphological and Fourier transform infrared microspectroscopy (mFTIR) analyses of intact sediments at the site of Wonderwerk Cave, Northern Cape province, South Africa, provide unambiguous evidence—in the form of burned bone and ashed plant remains—that burning took place in the cave during the early Acheulean occupation, approximately 1.0 Ma. To the best of our knowledge, this is the earliest secure evidence for burning in an archaeological context.

Very interesting!

Way to go Liora et al.!
