Llamas in the jungle? Or what do we know about the camelid presence on the eastern slopes of the Andes

Llamas (Lama glama) and alpacas (Vicugna pacos) are the only large, domesticated, and endemic mammals in the Peruvian Andes. They had immense significance for all pre-Columbian Andean cultures by providing essential resources such as meat, wool for textile production, bones for tool and ornament manufacturing, and dung used as fuel and fertilizer. Llamas and alpacas held an important place in pre-Columbian iconography. Their images were depicted on pottery, textiles, and on rocks in the form of petroglyphs and carvings. More robust llamas also served as pack animals and traversed the Andes in trade caravans.

Unfortunately for zooarchaeologists (scientists studying the relationships between humans and animals in the past), all South American camelid species are genetically related, which complicates their species identification if based solely on animal bones recovered during archaeological fieldwork. For this reason, in Andean zooarchaeology, they are conventionally referred to as “camelids.”

The story of a little rodent in a changing world

The summer of 9,750 BC (or 11,700 years before present) was warmer and rainier than usual in the area of the Kraków-Częstochowa Upland. At sunset, a solitary narrow-headed vole was walking across the hills, down to the Sąspow River and up to the highlands, in search of its favourite food to store for the winter, mainly shoots of grasses and sedges, every year more and more scarce and harder to find due to the advance of the forest. These were times of changes: only a few decades before, his great-grandparents were living in a suitable tundra environment with all the necessities: enough food in the summer, enough snow and ice in the winter to store their favourite grass seeds; in all the valleys were plenty of voles of his kind. Now all had changed. The solitary rodent was starving; he was the last of his kind in southern Poland. All his “family” moved northwards a long time ago because of global warming and the advance of the great forest.
