Transcript of Early Humans

Early Humans Ardipithecus Australopithecus Homo Habilis Homo Erectus Neanderthal Cro Magnon Early Humans Ardipithecus Australopithecus Homo Habilis Homo Erectus Cro Magnon Neanderthal Ardipithecus walked on Earth 4.4 million years ago in Eastern Africa. ‘Ardi’ was four feet tall and weighed 110 pounds. She also had a smaller brain then Lucy who was on Earth 3.5 million years ago. She survived off of nuts, berries, and insects. She lived in grasslands and grasslands. There has been no evidence showing that Ardipithecus had any ceremonies, wore clothing or talked. Although ‘Ardi’ didn’t make any tools she did use branches and stones. Something unique about her is that she was both bipedal and quadrapedal. This means that she was able to walk on all fours and on two feet. ‘Ardi’ also had a grasping toe. Ardipithecus is the missing link between humans and primates. Lucy was found by Donald Johannson. Her scientific name is Australopithecus but Donald Johannson and his team named her Lucy while they were celebrating the find. Lucy lived on Earth 3.5 million years ago in Hadar, Ethiopia. She stood at about three and half feet tall and weighed 60 to 65 pounds. Her brain was half the size of a modern human’s. She took shelter in grasslands and forests and ate bird’s eggs, insects, berries, leaves, fruits and roots. Also remains of dead animals. Lucy’s group possibly used stones and branches to kill their prey and to defend themselves. They didn’t have any ceremonies and didn’t wear clothes. Lucy wasn’t able to speak but possibly communicated with gestures. I thought that it was interesting that Lucy’s brain was bigger than the brain – to – body size ratio of an ape resulting her to have greater intelligence, better communication skills and the ability to work cooperatively. Homo habilis was lived on Earth 1.5 million years ago. Their brain size increased but only a little because it was still only half the size of a modern human’s. The Homo habilis was 4.5 feet tall and had a much more human looking face than Australopithecus. They lived in simple huts made from branches and held in place by stones. These shelters would have protected them from wind and animals. They were the first hominids to make and create tools. Homo habilis used branches and stones to kill their prey. They would chip sharp flakes of stone to use as knives to cut the meat. Homo habilis did not wear any clothes or have ceremonies. They hunted small animals, forged for plants, and took birds’ eggs. Although Homo habilis wasn’t able to talk, they made simple sounds and used primitive gestures. At this period in evolution humans began to be able to remember important information, plan ahead, and work out abstract problems so that they could make tools and organize hunts. 1.8 million years ago a new species began to evolve called Homo erectus. These early humans lived in Africa, Asia, and Europe. Their brains were bigger than Homo habilis but smaller than a modern human’s. Also, they had no chin. Homo erectus was the first species to walk completely upright. They lived in grasslands, planes and forests. After many generations when they migrated to Europe and Asia one group built a big hut with branches and two wooden posts to support it. They slept on animal skin. Homo habilis made tools and used fires. The fire came in use to scare away animals and cook food. They also made a sophisticated axe that could cut better than previous tools. They were capable of communication. To communicate, they grunted sounds and combined simple words with gestures. Homo erectus lived off of dandelion leaves, wild wheat, almonds, figs, berries, and quail’s eggs. They also ate rhinos, wild boar, deer and elephants. Homo erectus didn’t have any ceremonies. Since Homo erectus wasn’t able to make its own clothes, they draped fur over themselves. Cro magnons first walked on Earth 400,000 years ago. They migrated to Africa, Asia, and Europe by 30,000 years ago. By 11,000 years ago every continent but Antarctica was populated by humans because the Cro magnons had used the land bridges that only existed in the Ice Age to occupy that land. They were about five and a half feet tall. Their bodies were strong and heavy with a lot of musculature. Their faces were short and wide. Their brains were somewhat larger than the average for modern humans. Cro magnons lived in caves and huts and used fire to cook their food. These humans were the first of our ancestors to develop clear speech. They developed a more advanced language. Cro magnons diet were large mammals such as woolly rhinos, mammoths or saber tooth tigers which was done by men. Women forged for wild carrots, beets, onions, turnips, cabbage, celery, fruits, and berries and shellfish, eggs, and small animals. Cro magnons were the first ones to sew their own clothes. They also wore necklaces made with bits of eggshells, shells; fish bones. They had ceremonies and burials where they celebrated boys’ transition into a man, hunting and the seasons. Something about them that was interesting was that they enjoyed music during their celebrations. By Anjali Agarwal I will show you everything I have learned about them now...... Neanderthal first appeared on Earth 200,000 years ago in Africa. They were short, stocky people with big muscles. Their brains were equal to or larger than modern humans. They took shelter in caves. Neanderthal used fire and they cooked their food on it. Their diet was wild boar, deer, rabbit, bear, shellfish, mussels, dolphins, and seals. Neanderthal celebrated some ceremonies. They had burial ceremonies where the deceased would be buried with tools and food. Then they would be covered with flowers. Neanderthal made their own clothes out of leather that they softened and grass. These people were the first to belief in an afterlife. They may have pondered the question of death. We have been learning
about early humans Next is.... After that.... Homo Habilis is next.... Neanderthal is another interesting early human.... Last but not least is Cro Magnon.... Thank you for watching :)
