Linguistics vs. archeology and (physical) anthropology
Subtitle: "A cautionary note on the application of limited linguistics studies to whole populations"
A prefatory note on "anthropology". In the early 90s, I was deeply involved in the first ancient DNA studies on the Tarim mummies* with Paolo Francalacci, an anthropologist at the University of Sassari. Sardinia. Paolo was deputed to work with me by the eminent population geneticist, Luigi Luca Cavalli-Sforza of the Stanford medical school genetics department, who was unable to endure the rigors of the expedition to Eastern Central Asia.

After we had collected the tissue samples in the field, Paolo took them back to Sassari to extract and analyze the attenuated DNA. This involved amplification through PCR (polymerase chain reaction), a process that later gained great fame during the years of the coronavirus pandemic, inasmuch as it is an essential step in the detection and quantification of messenger RNA (mRNA). Indeed, two Penn scientists, Drew Weissman and Katalin Karikó, were awarded the 2023 Nobel Prize in Physiology or Medicine for their work on mRNA technology, which was crucial in the development of COVID-19 injections.
