Final answer:
Illicit looting in northern Peru has negatively impacted the archaeological record, resulting in the loss of artifacts and the destruction of sites. Inca sites like Machu Picchu are often targeted due to their cultural significance, and remote and unprotected sites are vulnerable as well.
Step-by-step explanation:
Illicit looting has had a significant impact on the archaeological record of northern Peru. This region is rich in ancient artifacts and archaeological sites, making it a prime target for looters. The looting has resulted in the loss of valuable artifacts and the destruction of archaeological sites, which hinders our understanding of the region's history and culture.
Many of the looting incidents have occurred in Inca sites, such as Machu Picchu, due to their cultural significance and the value of the artifacts they contain. Additionally, remote and unprotected sites are often targeted, as they are less likely to have security measures in place. The looting is driven by the black market demand for ancient artifacts, as they can fetch high prices among collectors, museums, and private buyers.
