Inhabited termite mounds along the Buffels River in Namaqualand, South Africa, are an astounding 34,000 years old, according to a new study. Termites are a diverse group of insects that play a vital ecological role by breaking down organic matter. They live in complex social groups, and some species create large underground nests. These can include extensive tunnels and chambers where the termites live and store plant material. Some termite mounds can be very old; in 2018, researchers discovered termite mounds in Brazil that were 4,000 years old. But a recent Science of The Total Environment study has discovered that termite mounds inhabited by southern harvester termites (Microhodotermes viator) in Namaqualand are far, far older. Using radiocarbon dating, the researchers found that the mounds have been used by termites for 34,000 years, since before the last Ice Age. During this period, humans were busy making cave art while a few Neanderthals were still hanging on in southern Europe. The world was still full of megafauna like woolly mammoths, saber-toothed cats and giant sloths. The study also gives an unparalleled view of the past climate cycles in the region, and points to a previously unexplored role of termites in storing carbon, says Michele Francis, a senior lecturer at Stellenbosch University and the study’s lead author. “Our gut told us [the mounds] were special, and when we dug through and saw these old nests and termites, we thought ‘wow,’” Francis says. “It’s like watching a video of the past.” Purple wildflowers growing…This article was originally published on Mongabay
