Arrowheads and Other Prehistoric Hunter Tools

Arrowheads and Other Prehistoric Hunter Tools Arrowheads are the most easily identified type of archaeological artifact. Most people in the world recognize an arrowhead when they see one: It is a stone object which has been deliberately reshaped to be pointy on one end. Whether theyve personally collected them from nearby farmlands, seen them in museum displays, or just watched them being shot into people in old western movies, most people know the triangular tips of arrow shafts called arrowheads are the remnants of a prehistoric hunting trip, the spent shotgun shells of the past. But why do archaeologists insist on calling them projectile points?   Arrowheads versus Projectile Points Archaeologists typically call what regular people call arrowheads projectile points, not because it sounds more academic, but because the shape of a pointy stone does not necessarily categorize it as something that was used at the end of an arrow shaft. Projectile is more inclusive than arrow. Also, in our long human history, we have used a wide variety of materials to put sharp points on the ends of projectiles, including stone, wood, bone, antler, copper, plant parts, and other raw material types : Sometimes we just sharpened the end of a stick. The purposes of projectile points have always been both hunting and warfare, but the technology has varied a great deal over the ages. The technology that made the first stone points possible was invented by our distant ancestor Homo erectus in Africa during the later Acheulean period, circa 400,000–200,000 years ago. This technology involved knocking bits of stone off a hunk of rock to create a sharp point. Archaeologists call this early version of stone-making the Levallois technique or Levalloisian flaking industry. Middle Stone Age Innovations: Spear Points During the Mousterian period of the Middle Paleolithic beginning around 166,000 years ago, Levalloisian flake tools were refined by our Neanderthal cousins and became quite numerous. It is during this period that stone tools were probably first attached to spears. Spear points, then, are projectile points that were attached to the end of a long shaft  and used to help hunt big mammals for food, either by hurling the spear at the animal  or by thrusting it into the animal at close range. Solutrean Hunter-Gatherers: Dart Points A great leap in hunting technology was made by Homo sapiens and occurred during the Solutrean part of the Upper Paleolithic period, about 21,000 to 17,000 years ago. Known for great artistry in stone point production (including the delicate but effective willow leaf point), the Solutrean people are also probably responsible for the introduction of the atlatl or throwing stick. The atlatl is a sophisticated combination tool, formed out of a short dart shaft with a point socketed into a longer shaft. A leather strap hooked at the far end allowed the hunter to fling the atlatl over her shoulder, the pointed dart flying off in a deadly and accurate manner, from a safe distance. The sharp end of an atlatl is called a dart point. By the way, the word atlatl (pronounced either at-ul at-ul or aht-lah-tul) is the Aztec word for the throwing stick; when Spanish conquistador Hernan Cortes landed on the eastern shore of Mexico in the 16th century CE he was greeted by atlatl-wielding individuals. True Arrowheads: The Invention of the Bow and Arrow The bow and arrow, a rather more familiar technological innovation to fans of John Wayne movies, also dates at least to the Upper Paleolithic, but it likely predates atlatls. The earliest evidence is 65,000 years old. Archaeologists usually call these arrow points, when they recognize them. All three types of hunting, the spear, the atlatl, and the bow and arrow, are used today by sportsmen around the world, practicing what our ancestors used on a daily basis.

Raul Castro Biography and Profile

Raul Castro Biography and Profile Raà ºl Castro (1931-) is the current President of Cuba and brother of Cuban Revolution leader Fidel Castro. Unlike his brother, Raà ºl is quiet and reserved and spent most of his life in his older brother’s shadow. Nevertheless, Raà ºl played a very important role in the Cuban Revolution as well as in the government of Cuba after the revolution was over. Early Years Raà ºl Modesto Castro Ruz was one of the  several illegitimate children born to sugar farmer Angel Castro and his maid, Lina Ruz Gonzlez. Young Raà ºl attended the same schools as his older brother but was neither as studious nor gregarious as Fidel. He was just as rebellious, however, and had a history of discipline problems. When Fidel became active in student groups as a leader, Raà ºl quietly joined a student communist group. He would always be as ardent a communist as his brother, if not more so. Raà ºl eventually became a leader himself of these student groups, organizing protests and demonstrations. Personal Life Raà ºl married his girlfriend and fellow revolutionary Vilma Espà ­n not long after the triumph of the revolution. They have four children. She passed away in 2007. Raà ºl leads an austere personal life, although there have been rumors that he may be an alcoholic. He is thought to despise homosexuals and reputedly influenced Fidel to jail them in the early years of their administration. Raà ºl has been consistently dogged by rumors that Angel Castro was not his real father. The most likely candidate, former rural guardsman Felipe Miraval, never denied nor confirmed the possibility. Moncada Like many socialists, Raà ºl was disgusted by the dictatorship of Fulgencio Batista. When Fidel began planning a revolution, Raà ºl was included from the start. The first armed action of the rebels was the July 26, 1953, attack on the federal barracks at Moncada outside of Santiago. Raà ºl, barely 22 years old, was assigned to the team sent to occupy the Palace of Justice. His car got lost on the way there, so they arrived late, but did secure the building. When the operation fell apart, Raà ºl and his companions dropped their weapons, put on civilian clothes, and walked out onto the street. He was eventually arrested. Prison and Exile Raà ºl was convicted of his role in the uprising and sentenced to 13 years in prison. Like his brother and some of the other leaders of the Moncada assault, he was sent to the Isle of Pines prison. There, they formed the 26th of July Movement (named for the date of the Moncada assault) and began plotting how to continue the revolution. In 1955 President Batista, responding to international pressure to release political prisoners, freed the men who had planned and carried out the Moncada assault. Fidel and Raà ºl, fearing for their lives, quickly went into exile in Mexico. Return to Cuba During their time in exile, Raà ºl befriended Ernesto â€Å"Chà ©Ã¢â‚¬  Guevara, an Argentine doctor who was also a committed communist. Raà ºl introduced his new friend to his brother, and the two hit it right off. Raà ºl, by now a veteran of armed actions as well as prison, took an active role in the 26th of July Movement. Raà ºl, Fidel, Chà ©, and new recruit Camilo Cienfuegos were among the 82 people who crowded on board the 12-person yacht Granma in November 1956 along with food and weapons to return to Cuba and start the revolution. In the Sierra Miraculously, the battered Granma carried all 82 passengers the 1,500 miles to Cuba. The rebels were quickly discovered and attacked by the army, however, and less than 20 made it into the Sierra Maestra Mountains. The Castro brothers soon began waging a guerrilla war against Batista, collecting recruits and weapons when they could. In 1958 Raà ºl was promoted to Comandante and given a force of 65 men and sent to the north coast of Oriente Province. While there, he imprisoned about 50 Americans, hoping to use them to keep the United States from intervening on behalf of Batista. The hostages were quickly released. Triumph of the Revolution In the waning days of 1958, Fidel made his move, sending Cienfuegos and Guevara in command of most of the rebel army, against army installations and important cities. When Guevara decisively won the Battle of Santa Clara, Batista realized he could not win and fled the country on January 1, 1959. The rebels, including Raà ºl, rode triumphantly into Havana. Mopping Up After Batista In the immediate aftermath of the revolution, Raà ºl and Chà © were given the task of rooting out supporters of former dictator Batista. Raà ºl, who had already begun setting up an intelligence service, was the perfect man for the job: he was ruthless and totally loyal to his brother. Raà ºl and Chà © oversaw hundreds of trials, many of which resulted in executions. Most of those executed had served as policemen or army officers under Batista. Role in Government and Legacy As Fidel Castro transformed the revolution into government, he came to rely on Raà ºl more and more. In the 50 years after the revolution, Raà ºl served as head of the Communist Party, minister of defense, vice president of the Council of State, and many more important positions. He has generally been most identified with the military: he has been Cuba’s top-ranking military officer since soon after the Revolution. He advised his brother during times of crisis such as the Bay of Pigs Invasion and the Cuban Missile Crisis. As Fidel’s health faded, Raà ºl came to be considered as the logical (and perhaps the only possible) successor. An ailing Castro turned over the reins of power to Raà ºl in July 2006, and in January 2008 Raà ºl was elected president in his own right, Fidel having withdrawn his name from consideration. Many see Raà ºl as being more pragmatic than Fidel, and there was some hope that Raà ºl would loosen the restrictions placed on Cuban citizens. He has done so, although not to the extent that some expected. Cubans can now own cell phones and consumer electronics. Economic reforms were implemented in 2011 to encourage more private initiative, foreign investment, and agrarian reforms. He limited terms for president, and he will step down after his second term as president ends in 2018. Normalization of relations with the United States began in earnest under  Raà ºl, and full diplomatic relations were resumed in 2015. President Obama visited Cuba and met with  Raà ºl in 2016. It will be interesting to see who succeeds Raà ºl as President of Cuba, as the torch gets handed to the next generation. Sources Castaà ±eda, Jorge C. Compaà ±ero: The Life and Death of Che Guevara.
