Human modification of natural landscapes has influenced surface processes in many settings on Earth. Quantitative data comparing the distribution and behavior of geologic phenomena before and after human arrival are sparse but urgently required to evaluate possible anthropogenic influences on geologic hazards. We conduct field and imagery-based mapping, statistical analysis, and numerical model...

this research wants to consider the formation process of outline and spotted shapes in prehistoric periods. the light and the various form of its reflection, which appears as a shadow, silhouette and lightfast, and the way of facing human with nature surrounding him, is the theoretical base of this paper. light is one of the important elements in nature which help human to know and comprehend i...

nature has great importance on prehistoric human life and attention to the environment and discovering mysteries of life which influence their life, always have been considered as concerns of prehistoric people. the elements such as water, wind and earth for primary human were important elements because of no awareness of environment in primary stages of sedentary life. human beings always trie...

By terms-allowed-in-types capacity, the Logic of Proofs LP includes formulas of the form t : φ(t), which have self-referential meanings. In this paper, “prehistoric phenomena” in a Gentzen-style formulation of modal logic S4 are defined. A special phenomenon, i.e., “left prehistoric loop”, is then shown to be necessary for self-referentiality in S4-LP realization.

A Prehistoric Mural in Spain Depicting Neurotropic Psilocybe Mushrooms? The Selva Pascuala mural, a work of post-Paleolithic rock art in Spain, contains fungoid figures herein hypothesized to depict neurotropic fungi, especially Psilocybe hispanica, a species that occurs in a neighboring region. This hypothesis is based on features of these figures related to fungal morphology, along with ethno...

There is a wealth of archaeological evidence, from bones excavated in prehistoric middens, piles of fruit stones and sea shells, that give us concrete indications of food consumed at various prehistoric sites around Europe. Added to this information we have pollen analysis from settlement sites and charred plant macrofossils. Wetland archaeology informs us in much more detail not just which foo...

As was made clear in the Introduction to this section on prehistoric maps, historians of cartography have had little to say on prehistoric cartography in the Old World. Neither Richard Andree nor Wolfgang Drober said anything at all. 1 In 1910 Bruno F. Adler discussed two decorated bone plaques that a German antiquarian, Fritz Rodiger, had suggested were maps, but he omitted both from his corpu...

Paleoanthropology emerged as a science during the late nineteenth century. The discovery of prehistoric artifacts in Pleistocene deposits soon led to the excavation of fossilized human bones. The archaeologists and geologists who unearthed them were primarily concerned with determining whether the human fossils and the artifacts found with them actually dated from the Pleistocene, thus offering...

Ancient mitochondrial DNA (mtDNA) mainly from Jomon Period Sus scrofa bone specimens (6,100-1,700 years old) was examined to clarify the genetic relationships between prehistoric and contemporary S. scrofa on Hokkaido, Honshu, Sado, and Izu islands of the Japanese Archipelago. Phylogenetic analysis of the mtDNA control region (574 bp) and analysis of pairwise nucleotide differences between preh...
