Cavalli Sforza (father and son) wrote The Great Human Diasporas, the History of Diversity and Evolution” back in 1993. Bryan Sykes has done something very like that in his Saxons, Vikings, and Celts. Cochran and Harpending have gone beyond Sykes in some respects but not hugely so. Interesting. So here we may have a thread to consider in what Oxonians call "The History of Ideas," ironically. I checked bits of Cavalli Sforza (father) in Wikipedia, and would be led to believe that his theory was best formulated once his settled at Stanford, but I guess one can find roots in his way of thinking other than Stanford-related authors! Wikipedia spends some time as to how to CALL this area of study or research, but I'm not convinced that one label is better than any other, so I chose to use "Cavalli Sforza" as subject line! The Wikipedia has a segment on criticisms to the approach that may interest L. Helm. They (the first of the two paragraphs below of a 'critical evaluation') are in ps. Cheers, Speranza From Wikipedia's entry on Cavalli Sforza: "Cavalli-Sforza's proposed Human Genome Diversity Project to gather further genetic data from populations around the world did not advance as he originally envisioned the project. News articles about his proposal noted that (unnamed) critics of the project decried it for "cultural insensitivity, neocolonialism, and biopiracy."" "Cavalli-Sforza has conducted several studies of how language differences may serve as barriers to gene flow between adjacent human populations. His studies of human migration have tested hypotheses of linguists Merritt Ruhlen and Joseph Greenberg about language "superfamilies." The hypothesized superfamilies are controversial among other linguists." ------------------------------------------------------------------ To change your Lit-Ideas settings (subscribe/unsub, vacation on/off, digest on/off), visit www.andreas.com/faq-lit-ideas.html
