Modern archeology\anthropology\paleontology is about funding, politics, orthodoxy and ego. Worse than these forums.
The Solutrean theory if correct, dry's up PBS specials, summer fun in the woods, paychecks, fame, book deals, tenure and scientific authority for a lot of people who other wise have to get real jobs while watching their publications loose validity.
All of the camps involved on the status quo side are smart enough to prove the Solutrean migration to the east coast is possible. Once they do that, they stop being the status quo.
