Forthcoming. Response to comment by Bergfjord et al. Science.0036-8075http://nrs.harvard.edu/urn-3:HUL.InstRepos:4064022The comment by Bergfjord et al. expresses doubts concerning the possibility of identifying flax fibers on the basis of the morphology of their internal layers. The authors use microphotographs and descriptions of the outer layers of fibers as arguments for their claims. Morphology and structure of the outer and inner parts of fibers are radically different, and for that reason the methodological approach of Bergfjord et al. is questionable.en-USJournal Article2010-05-11
