The making of ritual shrunken heads, or tsantsas, was a common practice among the Jivaro-Shuar tribes of Ecuador and Peru during the post-Columbian period. The raising interest in the tsantsas in the late nineteenth through the twentieth century caused an increase in manufacturing of forged shrunken heads for profit. In the current study, we examined the authenticity and possible cultural provenance of the shrunken head displayed at the “Eretz Israel Museum, Tel Aviv” using macro- and microscopic criteria together with DNA analyses. DNA analyses have revealed that the shrunken head represents a human male individual with a genetic profile compatible with an African ancestry and resembling that of modern South American populations.  相似文献

It is sixteen years since the first detection of Mycobacterium tuberculosis DNA in archaeological specimens, yet the validity of findings continues to be questioned. Rigorous scientific scrutiny and debate is valuable and has led to a coalescence of procedures and precautions amongst those actively engaged in this work. It is disappointing that these good practices are not recognised by certain scientists whose primary expertise is in the related fields of archaeology, palaeopathology, and eukaryote ancient DNA. There is a danger that by constant repetition, disputable and inadequately justified concerns will assume the status of self-perpetuating myths and misunderstandings. We discuss these issues with reference to a recent article in this journal, in which clear peer-reviewed scientific data were specifically targeted as part of a general critique of the field of the palaeomicrobiology of tuberculosis. We believe we have given sufficient evidence and cogent argument to persuade the unbiased reader that the views in the critique by Wilbur et al. are unjustified.  相似文献

The evidence for wild sheep (Ovis orientalis) in archaeological sites from the southern Levant is examined through the application of ancient DNA analysis to specimens from the Pre‐Pottery Neolithic A (8300–7500 uncal. BC) site of Hatoula, Israel. The results indicate that at least one of the bones from this site, previously identified as sheep, is in fact goat. To date this is the earliest faunal sample to have yielded DNA in the region. This study highlights the problems in applying morphological criteria to distinguish between caprine species, and illustrates how ancient DNA analysis can serve as a powerful tool in resolving questions of species attribution.
