Very new like last 100 yrs or last 1000 yrs?....Prions were maybe positively identified in 1960s, but Creutzfeldt described the disease in 1920s and "scrapie" was described by sheep herders centuries agoScientists and biologists are confident that the disease was very new when it was discovering in captive cervids in the late 60s.
