UAF Professor coauthors study in Science magazine
by Lex Treinen
UAF Professor of Fisheries and Ocean Sciences Dr. Matt Wooller’s isotopic analysis of a 9,000-year-old tooth was published in Science, one of the most prestigious journals in the country.
Wooller’s work allowed insight as to the diets of some of the first inhabitants of Alaska based on a nearly-forgotten artifact from a cave on the Seward Peninsula. His work led to a counter-intuitive finding.
“The site is surrounded by ocean and yet what we found chemically in the tooth was signatures that were more consistent with a terrestrial-based sources of food compared with marine sources despite marine resources surrounding the site,” he said.
Wooller said that this finding was particularly puzzling considering that the only other known site of these people, whom archaeologists call the Ancient Beringians, is in Interior Alaska on the Upward Sun site on the Tanana River. Paradoxically, those isotopic analyses showed a strong preponderance of marine food sources.
