An international team of archaeologists has discovered preserved plant beds and evidence of the use of insect repellent plants 77,000 years ago in a rock shelter in southern Africa.
This discovery, which dates back 50,000 years longer than previous reports bedding preserved, offers a fascinating insight into the performance practices of early modern humans in Africa.
The team, led by Professor Lyn Wadley of the University of Witwatersrand in South Africa, in collaboration with Christopher Miller, University of Tübingen, Germany, Christine Bamford Marion Sievers and also of the Witwatersrand, and Paul Goldberg and Francesco
Berne Boston University in the United States have described the discovery in the journal Science.
The old bed was discovered during excavations in Sibudu, a rock shelter in the province of KwaZulu-Natal (South Africa), where Lyn Wadley, a professor at the University of Witwatersrand has been excavating since 1998. At least 15 different layers contain
bedding, between 77,000 and 38,000 for years. The bedding consists of layers of several centimeters thick compact stems and leaves of reeds, which extend for at least one square meter and a maximum of three square meters in the excavated area. Christine Sievers,
University of Witwatersrand, nutlets identified several types of reed used in the construction of the bedding.
