Valentine Sapunov, academician of Russian Academy of Sciences, reported about the sensational results of hair analysis of Yeti on the electron microscope. The investigations revealed, that all four samples of yeti hair, which were found in different places of Earth (in California, in the Ural, in the Leningrad region and in a cave in the Kemerovo region) belong to the same biological species. However, this species is not described in any directory, as the samples of hair can not belong to any known species. Thus,this is the first scientific evidence, that Bigfoot really exists in nature as a separate species, because it was very difficult to fake hair samples, taken at different places of the Earth.
