Although no one knows exactly when or how people crossed into North America, evidence suggests that people called Paleo-Indians crossed this bridge into Alaska between 38,000 and 10,000 BC. This migration — a movement of people or animals from one region to another—took place over a long time. It is believed that Paleo-Indians traveled south into Canada, the United States, and Mexico following herds of animals. Over time, their descendants went as far as the southern tip of South America. These people were hunter-gatherers , people who hunted animals and gathered wild plants for food. 6 CHAPTER 1 DO NOT EDIT--Changes must be made through “File info” CorrectionKey=TX-A Land Migrations of Early Peoples ASIA 180˚ 0˚ HRW US History t 170˚W ai tr ah06se_c01loc003aa S 160˚W ng eri 10˚W Migrations Locator B 150˚W 70˚N F1 proof 10/04/04 140˚W 20˚W 130˚W Approved 10/28/04 e l c About 8000 BC, ir C c ALASKA ti Earth’s climate grew rc A 30˚W warmer, and the Ice Age ended.

A CONSIDERATION OF TIME AND LABOR EXPENDITURE IN THE CONSTRUCTION PROCESS AT THE TEOTIHUACAN PYRAMID OF THE SUN AND THE POVERTY POINT 14)UND Stephen Aaberg and Jay Bonsignore INTRODUCT ION In considering the subject of prehistoric earthmoving and the construction of monuments associated with it, there are many variables for which some sort of control must be achieved before any feasible demographic features related to the labor involved in such construction can be derived. Many of the variables that must be considered can be given support only through certain fundamental assumptions based upon observations of related extant phenomena. Many of these observations are contained in the ethnographic record of aboriginal cultures of the world whose activities and subsistence patterns are more closely related to the prehistoric cultures of a particular area. In other instances, support can be gathered from observations of current manual labor related to earth moving since the prehistoric constructions were accomplished manually by a human labor force. The material herein will present alternative ways of arriving at the represented phenomena. What is inherently important in considering these data is the element of cultural organization involved in such activities. One need only look at sites such as the Valley of the Kings and the great pyramids of Egypt, Teotihuacan, La Venta and Chichen Itza in Mexico, the Cahokia mound group in Illinois, and other such sites to realize that considerable time, effort and organization were required.

    Recent North Magnetic Pole Acceleration Towards Siberia Caused by flux Lobe Elongation

    Recent north magnetic pole acceleration towards Siberia caused by flux lobe elongation Philip W. Livermore,1∗, Christopher C. Finlay 2, Matthew Bayliff 1 1School of Earth and Environment, University of Leeds, Leeds, LS2 9JT, UK, 2DTU Space, Technical University of Denmark, 2800 Kgs. Lyngby, Copenhagen, Denmark ∗To whom correspondence should be addressed; E-mail: [email protected]. Abstract The wandering of Earth’s north magnetic pole, the location where the magnetic field points vertically downwards, has long been a topic of scien- tific fascination. Since the first in-situ measurements in 1831 of its location in the Canadian arctic, the pole has drifted inexorably towards Siberia, ac- celerating between 1990 and 2005 from its historic speed of 0-15 km/yr to its present speed of 50-60 km/yr. In late October 2017 the north magnetic pole crossed the international date line, passing within 390 km of the geo- graphic pole, and is now moving southwards. Here we show that over the last two decades the position of the north magnetic pole has been largely determined by two large-scale lobes of negative magnetic flux on the core- mantle-boundary under Canada and Siberia. Localised modelling shows that elongation of the Canadian lobe, likely caused by an alteration in the pattern of core-flow between 1970 and 1999, significantly weakened its signature on Earth’s surface causing the pole to accelerate towards Siberia. A range of simple models that capture this process indicate that over the next decade arXiv:2010.11033v1 [physics.geo-ph] 21 Oct 2020 the north magnetic pole will continue on its current trajectory travelling a further 390-660 km towards Siberia.

Cordell, University of Colorado, Boulder, CO, and approved October 30, 2009 (received for review June 22, 2009) Our understanding of the initial period of agriculture in the southwestern United States has been transformed by recent discoveries that establish the presence of maize there by 2100 cal. B.C. (calibrated calendrical years before the Christian era) and document the processes by which it was integrated into local foraging economies. Here we review archaeological, paleoecological, linguistic, and genetic data to evaluate the hypothesis that Proto-Uto-Aztecan (PUA) farmers migrating from a homeland in Mesoamerica intro- duced maize agriculture to the region. We conclude that this hypothesis is untenable and that the available data indicate instead a Great Basin homeland for the PUA, the breakup of this speech community into northern and southern divisions Ϸ6900 cal.

    SIXTH ASSESSMENT REPORT Working Group I – The Physical Science Basis Regional fact sheet – North and Central America Common regional changes • North and Central America (and the Caribbean) are projected to experience climate changes across all regions, with some common changes and others showing distinctive regional patterns that lead to unique combinations of adaptation and risk-management challenges. These shifts in North and Central American climate become more prominent with increasing greenhouse gas emissions and higher global warming levels. • Temperate change (mean and extremes) in observations in most regions is larger than the global mean and is attributed to human influence. Under all future scenarios and global warming levels, temperatures and extreme high temperatures are expected to continue to increase (virtually certain) with larger warming in northern subregions. • Relative sea level rise is projected to increase along most coasts (high confidence), and are associated with increased coastal flooding and erosion (also in observations). Exceptions include regions with strong coastal land uplift along the south coast of Alaska and Hudson Bay. • Ocean acidification (along coasts) and marine heatwaves (intensity and duration) are projected to increase (virtually certain and high confidence, respectively). • Strong declines in glaciers, permafrost, snow cover are observed and will continue in a warming world (high confidence), with the exception of snow in northern Arctic (see overleaf). • Tropical cyclones (with higher precipitation), severe storms, and dust storms are expected to become more extreme (Caribbean, US Gulf Coast, East Coast, Northern and Southern Central America) (medium confidence).

El presente curso pretende ofrecer una visión de los elementos y períodos culturales que identifican al México Antiguo. Las regiones son: oasisamérica, aridoamérica y mesoamérica Los horizontes que la componen son: arqueolítico, cenolítico inferior, cenolítico superior, protoneolítico, oasisamérica, aridoamérica, mesoamérica y los primeros contactos en el s. XVI: Planteamiento que se hace de esta manera para una mejor comprensión del curso y entender la evolución de los grupos asentados en territorio mexicano. 2.Fundamentación. Las área culturales del México Antiguo no solo se reduce a Mesoamérica como el período de máximo florecimiento que le antecedió a la conquista. En otros tiempos, antes de conocerse esta macroárea cultural, llegaron diversos grupos de cazadores-recolectores nómadas. El proceso evolutivo de estos grupos fue largo y lento, permitiendo avanzar e ir tocando diferentes niveles de desarrollo y los conocimientos necesarios para el cultivo y domesticación de las plantas como uno de los descubrimientos mas importantes durante esta fase que cambio el curso de la historia. Otra de las regiones es la llamada Oasisamérica localizada al sw de E.U. y norte de México, compuesta por grupos sedentarios agrícolas pero con una complejidad similar a la Mesoamericana. El área denominada mesoamérica, espacio donde interactuaron y se desarrollaron diversos grupos culturales, fue la “…sede de la mas alta civilización de la América precolombina. (Niederbeger, 11, 1996), se desarrollo en la mayor parte del territorio mexicano. Mesoamérica, definida así por Kirchhoff en 1943, es punto de referencia no solo para estudiosos del período prehispánico, en el convergen diversos especialistas amparados en diferentes corrientes ideológicas y enfoques: antropólogos, geógrafos prehistoriadores, historiadores, sociólogos, arquitectos, biólogos, sociólogos, por mencionar a algunos.
