One fish, two fish, old fish, new fish: Investigating differential distribution of salmon resources in the Pacific Northwest through ancient DNA analysis

摘要: DNA analysis was applied to approximately 60 ancient salmon remains (1200BP) from the archaeological site of Keatley Creek in British Columbia examine distribution Pacific species between housepits. The success rate extraction over 90%, yielding three salmon: Chinook, Sockeye and Coho. Accurate identification using mitochondria1 refined theories economic stratification differential access resources at Creek. Additionally, unique information made available by offered insight into prehistoric ecology spawning behaviour region.
