Hole in the head
Download as ppt, pdf1 like389 views
The document describes a human skull artifact found in Peru that has a hole in it. Similar skulls have been found worldwide. The archaeological team must determine the significance of the holes, who made them, how they were made, and why. The holes were likely deliberately made while the individuals were alive, as the bone shows healing. The procedure is called trepanation and was used by prehistoric peoples and later societies to treat medical issues believed to have supernatural causes. Tools used may have resembled carpenters' bits made of stone or bronze.

Henry VIII broke from the Catholic Church and established the Church of England after the Pope refused to annul his marriage to Katharine of Aragon so he could marry Anne Boleyn. This began the English Reformation. His daughter Elizabeth I further reformed the Church of England and established it as the sole legal church in England during her reign, though she faced conflicts with Catholics and financial issues with Parliament.Fishery in Philippines

This document provides an overview of human origins and early history based on archaeological and anthropological evidence. It describes how early hominids evolved in Africa between 5-1 million years ago, including Australopithecines and Homo habilis. Homo erectus emerged around 1.5 million years ago and were the first to leave Africa. Homo sapiens developed around 250,000 years ago, while anatomically modern humans appeared in Africa between 150,000-200,000 years ago. The Neolithic agricultural revolution began around 10,000 BC, leading to permanent settlements like Catal Huyuk and the emergence of early civilizations.The case of evolution & creation

This document provides an overview of arguments against key aspects of evolutionary theory from a creationist perspective. It examines perceived problems with theories of common descent, the fossil record evidence for human evolution, and several historical examples of fossils that were misidentified or fabricated. Through quotes and images, it aims to cast doubt on the evolutionary relationships between modern species and their supposed ancestors like Homo habilis, Australopithecus, and others. The document advocates interpreting the scientific evidence through a biblical lens and defines faith in evolution as believing in links that are not seen in the fossil record.Understanding Our Past

The document discusses prehistoric medicine and compares it to practices of Australian Aborigines. It notes that prehistoric people performed trephining operations on skulls, as evidenced by healed bone growth. Historians have proposed various theories for why, including drinking vessels or releasing evil spirits. The document also describes how Aborigines used spiritual explanations and natural remedies for illnesses and injuries, treating wounds with clay or animal fat and broken bones with hardened clay casts. Their spiritual explanations involved evil spirits causing illnesses or a person's spirit leaving their body.Tools of early humans
Tools of early humansMs Wilson
油
Early humans began appearing 1.2-4 million years ago and had to create tools to make survival easier. Australopithecus, the earliest known hominoid, lived 4-2 million years ago and used tools scavenged or found to hunt and gather food. Homo habilis, discovered in the 1960s, were the first to create tools and hunt but could not control fire. Homo erectus from 1.8 million years ago were stronger and smarter, able to control fire and make complex tools to hunt African and Asian game. Neanderthals from 400,000 years ago were strong and smart but died off, possibly from disease. Cro-Magnons from 40,000 years ago couldGroups of Hominids

Early humans like Homo habilis and Homo erectus lived in Africa around 2 million years ago and were the first to use stone tools. Homo erectus spread from Africa to Europe and Asia around 1 million years ago by crossing land bridges during ice ages. Later groups like Homo sapiens and Neanderthals were skilled hunters who controlled fire, made clothing and shelters, and buried their dead with ceremony. Neanderthals lived in Europe and West Asia from around 500,000 to 30,000 years ago before going extinct.Pre-history & Early Man [PDF]

Early humans originated in Africa around 2 million years ago. Fossil evidence shows that the earliest humans were Australopithecus who lived around 4 million years ago. Later hominids such as Homo Habilis and Homo Erectus developed increased brain size and the ability to walk upright. During the Ice Age starting 2.6 million years ago, early humans migrated from Africa across land bridges as glaciers advanced and retreated. Modern humans, Homo Sapiens, emerged around 200,000 years ago and Homo Sapiens Sapiens developed around 50,000 years ago. The development of language, tools, fire, and other cultural adaptations enabled humans to spread across the globe. Around 12,Trepanation Presentation by Karrah Christenson Session 8 2012

Martin Luther posted 95 theses criticizing the Catholic Church's sale of indulgences and other abuses on the door of the Wittenberg Church in 1517, sparking the Protestant Reformation. Luther argued that salvation comes through faith alone, not works or indulgences, and he translated the Bible into German so ordinary people could read it. His writings spread rapidly and attracted many followers, though the Catholic Church condemned Luther and his teachings. The Reformation led to divisions in Christianity between Protestantism and Catholicism that still exist today.Sci rev

The Scientific Revolution saw major changes in the European worldview as scientists like Copernicus, Galileo, Kepler, and Newton challenged previously accepted theories. Copernicus proposed the heliocentric model with the Sun at the center, contradicting the geocentric Ptolemaic system. Galileo made many important discoveries with the telescope, including Jupiter's moons, and proved theories of Aristotle wrong through experimentation. Kepler developed his three laws of planetary motion based on observations. Finally, Newton formulated the law of universal gravitation and viewed the universe as a giant, perfectly engineered clockwork. These revolutionary ideas shifted perception away from Earth as the center of the universe.The renaissance for web

There is also evidence that the bone around the holes had healed indicating that the persons were alive at the time of the procedure and survived. It might be concluded that the procedure was medical. Some have speculated that the purpose of the procedure was to relieve pressure from swelling in the brain.
- 16. Given what we know about the believe systems of many of these societies, one might conclude that the procedure was meant to address supernatural causes of illness. Prehistoric peoples as well as later societies believed that pain and conditions such as epilepsy and mental illness had supernatural causes.

- 18. The procedure is known as trepanation and it is one of the few medical procedures for which we have archaeological evidence. There is much speculation about the tools used in the procedure. It has been suggested that an instrument resembling a carpenters bit may have been used. The bit may have been made from obsidian or other stone, or even bronze. The procedure was particularly prevalent in what is today Peru.
