1 00:00:00,820 --> 00:00:31,219 Hello, today we're going to talk about prehistory. 2 00:00:31,219 --> 00:00:41,579 The period known as prehistory began when the first human beings appeared, about 2.5 million years ago. 3 00:00:43,579 --> 00:00:49,600 Prehistory ended when writing was invented, over 5,000 years ago. 4 00:00:50,140 --> 00:00:57,780 This period is divided into the Paleolithic Age, the Neolithic Age and the Metal Ages. 5 00:00:58,179 --> 00:01:03,240 The Paleolithic and Neolithic Ages are also known as the Stone Age. 6 00:01:04,200 --> 00:01:16,680 The Paleolithic Age. Paleolithic women and men lived from hunting, fishing and gathering fruit. 7 00:01:16,680 --> 00:01:24,980 they were predators. They were also nomads because they moved from one place to another 8 00:01:24,980 --> 00:01:33,659 looking for food and materials. They did not have permanent homes and often found refuge 9 00:01:33,659 --> 00:01:42,920 in caves or rock shelters. It was at this time that fire was discovered. Paleolithic 10 00:01:42,920 --> 00:01:49,000 Neolithic women and men were also responsible for making the first works of art, by engraving 11 00:01:49,000 --> 00:01:55,879 or painting the walls of caves and rock shelters. 12 00:01:55,879 --> 00:02:00,319 Cave paintings have been discovered in the Iberian Peninsula. 13 00:02:00,319 --> 00:02:07,959 One of these discoveries is the cave of Altamira, in the north of Spain. 14 00:02:07,959 --> 00:02:08,960 The Neolithic Age 15 00:02:08,960 --> 00:02:15,400 The Neolithic Age started when women and men learned to cultivate the land, which was the 16 00:02:15,400 --> 00:02:22,139 beginning of agriculture, and when they learned to domesticate animals, which was the beginning 17 00:02:22,139 --> 00:02:26,560 of livestock farming. 18 00:02:26,560 --> 00:02:31,139 Since humans now could produce their own food, they did not need to move from one place to 19 00:02:31,139 --> 00:02:33,139 another and became sedentary. 20 00:02:33,139 --> 00:02:40,139 This was the time when the first settlements appeared. 21 00:02:40,139 --> 00:02:46,139 The Neolithic settlements were located on flat, fertile ground near rivers and were 22 00:02:46,139 --> 00:02:51,139 usually surrounded by walls made of weeds and mud. 23 00:02:51,139 --> 00:02:59,780 The women and men lived in huts made of adobe. 24 00:02:59,780 --> 00:03:05,060 the metal agents metallurgy was invented 5 000 years before christ 25 00:03:05,699 --> 00:03:13,060 when humans discovered metal and how to work it settlements became larger and had stone walls 26 00:03:13,060 --> 00:03:23,539 around them skilled metal workers became artisans and soon after trade and transport developed 27 00:03:23,539 --> 00:03:34,419 The Metal Ages ended when writing was invented, about 3000 years before Christ.
