Paleoparasitological investigations on the Neolithic lakeside settlement of La Draga (Lake Banyoles, Spain)

Abstract

Paleoparasitological analyses were conducted on samples from the Neolithic lakeside settlement of La Draga in Spain (5320–4980 BC). Conventional microscopic analysis revealed the presence of tapeworms (genus Taenia/Echinoccocus and Diphyllobothrium), roundworms (genus Trichuris, Capillaria, and Ascaris), rumen fluke (genus Paramphistomum), and Acanthocephalan (genus Macracanthorhynchus). In addition, genetic analysis demonstrated the presence of the lancet liver fluke ( Dicrocoelium dendriticum) and the human pinworm ( Enterobius vermicularis) at the site. These results represent the first parasitological data from a Neolithic lakeside settlement related to the Cardial Pottery Culture. Some parasites are comparable with those retrieved from Neolithic lakeside sites studied in France, Germany, and Switzerland, which stem from and are posterior to the Linear Band Keramic Culture. However, some taxa were identified here for the first time during the Neolithic period, or represent the oldest mention of these parasites. This new paleoparasitological contribution reinforces our knowledge of intestinal parasites in Neolithic populations and provides new data on their history.
