Chimps have been reported dancing in rainstorms – and now it seems our closest relation has a "fire dance", too. A dominant male chimp performed such a dance in the face of a raging savannah fire in Senegal.
Anthropologist Jill Pruetz of Iowa State University in Ames recounts that the male faced the fire with "a really exaggerated slow-motion display" before redirecting his display at chimps sheltering in a nearby baobab tree. Barking vocalisations from the male, never heard in more than 2000 hours of monitoring the group, were also heard.
Pruetz and co-author Thomas LaDuke at the East Stroudsburg University of Pennsylvania suggest that the chimps were cognisant enough to predict the fire's movement, retreating short distances at a time while staying calm. Other animals, in contrast, panic when fire approaches.
"If chimps with their small brain size can conceptually deal with fire, then maybe we should rethink some of the earliest evidence for fire usage," Pruetz says. The earliest confirmed evidence of controlled fire use dates to several thousand years ago but some palaeoanthropologists argue control began as far back as 1 to 2 million years ago. The chimps' responses to two fires – set for land clearance – were seen in 2006.
