HistoryLate Neolithic (c. 2800-2400 BCE)Britain (Southern England, Wales, Scotland)high confidence

The vast majority of pigs eaten at late Neolithic ceremonial sites in southern England were not raised locally, but brought from different parts of Britain, including Wales and Scotland, from distances of at least 30 miles and potentially more than 350 miles.

Notes on verification

Confirmed by peer-reviewed Science Advances study (Madgwick et al. 2019) using isotope analysis of 131 pigs, corroborated by Cardiff University press release and independent science journalism (Smithsonian, Current Archaeology) with matching distance figures.
