In the 1970s Donald Johanson and his team were searching for fossils in East Africa and in 1974 Johanson and his team found a complete skeleton of an adult female hominid, which then was nicknamed Lucy. By carbon dating they found that Lucy lived roughly 3.5 million years ago. Lucy’s discovery is significant because to date she is the oldest hominid found with a complete skeleton. In the early 1978 Mary Leakey made an important discovery in Tanzania, which is located in East Africa. Mary Leakey and her team found prehistoric footprints that appeared to be footprints of modern humans. The footprints were preserved in volcanic ash. Upon further research, it came to be known that the footprints were made by “human-like beings now called australopithecines” …show more content…
Homo erectus adapted to their surroundings. Homo erectus lost most of their body hair, and developed a pelvis; the pelvis allowed bipedal travel for long distances. However, before this evolution of Homo habilis, there were many adaptations that helped put bipedalism into motion and allowing humans to move out of Africa and into other continents like Asia. The adaptation of a larger heel stabilized bipedal movement, the curve in the lumbar region of the spine allowed humans to stand upright, depth perception allowed us to see color, which allowed us to see and distinguish between safe and deadly plants. The development of a bigger brain helped inspire tool production, and a major advancement, how to build a fire. All of the adaptions helped humans rise to the top of the food chain.
As Homo sapiens evolved they began to farm, domesticate animals, which led to a genetic mutation that helps our digestive system digest lactose. Through further advancements, the brain became smaller, but more efficient and reduced aggressive behavior. Because humans became less aggressive, they were able to work in groups and live in small communities, which then again helped technological evolution. Technology such as tools are found in locations across the globe help archeologist date civilizations and Homo
In a search to find our ancestors, several anthropologists have found evidence to support their conclusions. In the films about Don Johanson's discovery of Lucy in Hadar, one may be very intrigued by the first film but very disturbed by the second film.
Humans are not the only species with the ability of making tools. Early on in her research, Jane Goodall observed an older male chimp, she called him David Greybeard. Through her observation of David, she witnessed two forms of the use of tools. The first was the use of grass as a tool to extract termites from their mounds. The second was the making of a tool by stripping the leaves off a twig, modifying it for the same purpose. When Louis Leakey heard this, he wrote her “Now we must redefine tool, redefine man, or except chimpanzees as humans” (Goodall, 2002). There is a definite correlation between man and chimps in this respect. Human culture involves learned behaviors through observation, imitation and practice, the use of tools with chimpanzees show the same ability for learned beh...
On November 24, 1974, an American Anthropologist by the name of Donald Johanson and his research team, made a ground-breaking discovery that caused a mass dispute in human evolution. Dr. Johanson documented in his book, Lucy The Beginning Of Mankind, the discoveries he and his team have come across. Dr. Johanson and his team discovered a skeleton of a hominid, dated between 3.9 to 3 million years old (164). The hominid, which they referred to as Lucy, was discovered while surveying Hadar, in the Dafar region of Ethiopia (164-166). Lucy’s discovery, a 41% complete human ancestor caused a controversial alteration in the human origins. Lucy was the oldest human ancestor. During the following year, Johanson’s team discovered fossilized remains
This paper has shown how Homo sapiens had several advantages over the Neanderthals including better diets, better tools and just better luck. The Neanderthals could not survive the harsh climates they were thrust into and eventually died out. In this paper I looked at how Homo sapiens and Homo neanderthalensis had co-existed but the disappearance of the Neanderthal ius due in some part to the appearance of the more culturally advanced and genetically superior Homo sapiens. Although the How and Why of how Neanderthals went extinct, it is clear that Homo sapiens had a part in their demise. In the last one hundred and fifty years that we have been studying humans we have seen them come from savage brutes, to Homo sapiens respectable contemporary. If we had not gotten lucky in the past, Neanderthals could be studying us today.
The archaeological record shows us what the intelligent ethnographers preach; there is more out there than what we see, and we are constantly underestimating the cultures that came before us. The widespread use of tools like harpoons and spears, the spread of pottery and boxes, and the actual contents of ancient stomachs (like the Ice Man's) show us that ancient people were once more variable than they are now. Considering that ancient men spread from Pittsburgh to South America in an incredibly short span of time (though from whence they came is unknown), ancient people must have been very adept at adapting.
The species A. afarensis is one of the better known australopithecines, with regards to the number of samples attributed to the species. From speculations about their close relatives, the gorilla and chimpanzee, A. afarensis’ probable social structure can be presumed. The species was named by Johanson and Taieb in 1973. This discovery of a skeleton lead to a heated debate over the validity of the species. The species eventually was accepted by most researchers as a new species of australopithecine and a likely candidate for a human ancestor.
The evolution of the human species has significantly changed during the course of evolution to what is now the modern day Homo sapiens. Some of the changes that have occurred through the evolution are bipedalism, changes in body features such as brow ridges, and an increase in brain capacity.
Humanity became fascinated with the idea of evolution with the work of Charles Darwin and the Scientific Revolution. People began hunting for fossils that would prove that man had an ape derived ancestry (Weiner, 1955). After various years of searching, a piece of physical evidence was found in England that was said to confirm the theory of evolution (Weiner, 1955).This confirmation came from Charles Dawson’s discoveries from 1908, that were announced publicly in 1912 (Thackeray, 2011). Dawson was believed to have found the fossil remains of the “missing link” between ape and human evolution, the reconstructed skull of Piltdown man (Augustine, 2006). The material was found in stratigraphical evidence and animal remains that were, at the time, adequate enough to confirm the antiquity of the remains (Weiner, 1955). In 1915, another specimen, Piltdown man II, was found further proving this theory (Augustine, 2006). However, this was merely a hoax proven by fluorine relative dating in 1953; the artifacts and bone fragments discovered turned out to be altered to fit the proposed scenario (Augustine, 2006). The skull found was actually composed of a human braincase that was younger than the complimentary orangutan lower jaw (Falk, 2011). Both sections of the skull had been stained to appear to be from the same person of the same age (Falk, 2011).The perpetrator of this act was never caught and there are many theories proposed for the motive of this hoax (Augustine, 2006). Many people have been taken into consideration for this crime, such as Chardin, Woodward, Hinton, and Dawson (Augustine, 2006). Nevertheless, the evidence that proves that Dawson is guilty of this crime against anthropology is quite substantial compared to the evidence...
“The scientific study of how humans developed did not begin until the 1800s in Europe. Until that time, people relied on religious explanations of how humans came into existence. Starting in the 1500s a scientific revolution began to sweep Europe. Thinkers started using scientific methods and experiments to try to better understand the world and the creatures living in it. Eventually these methods were turned to the question of human origins” (The Nature Of Human Origins, 1). Earth made it possible for species to change over time because Ancient Earth provides ability to plenty of time.The Homo Sapien a is very complex creature. The species started off very simple by living in caves and surviving with little food and then later evolved into a species that were able to do many more complex things. The first species was Sahelanthropus tchadensis They were one of the most simple humans in that time period and on. They had very small skulls compared to Homo Sapiens today and their motor skills were just the same. We have evolved and changed for the better both mentally and physically. The Evolution of Homo Sapiens started off simple, such as the Neanderthals, and now we are the most advanced species to ever walk the planet so far.
One of the most important and pivotal physical and biological adaptations that separate humans from other mammals is habitual bipedalism. According to Darwin, as restated by Daniel Lieberman, “It was bipedalism rather than big brains, language, or tool use that first set th...
The members of the Homo genus possess a combination of unique features that distinguish them from other related species. At the time that each respective species was alive, they were able to walk upright on two legs, use their large brains for the benefit of their species, and could thrive in many geographically and climatically diverse areas of the world. One of the most mysterious quandaries in science is how the lineage of the Homo genus became so different from their primate relatives. Bipedalism, brain size, and location diversity all have a common link that may explain this difference – dietary evolution allowed humans to adapt to their surroundings, and in turn, become a more advanced species. The Homo diet evolved in relation to food availability and nutritional necessity. With the ability to maintain a proper diet, the species of the Homo genus were able to flourish and advance toward the development of modern Homo sapiens.
The evidence for human evolution begins with the australopithecines. All the australopithecines were bipedal and therefore possible hominines. In details of their teeth, jaws, and brain size, however, they modify enough among themselves to be divided into five species: Australopithecus anamensis, A. afarensis, A. africanus, A. robustus, and A. boisei. Genus Homo are also divided in five different spices: Homo erectus, H. habilis, H. sapiens, and H. sapiens sapiens.
...d to the switch for calorie and protein rich animal products. Soon followed the creation of the revolutionary element; fire which changed the road of human evolution drastically. Homo erectus could now greatly increase the calories gained from food while also keeping warm and protecting from predators of the night. These campfires also led the some of the earliest forms of social interaction among early humans. Besides campfire interactions, Homo erectus also formed a distinct form of hunting and gathering division of labor which is still evident in parts of the world today. Though it is Homo erectus’s great migration out of Africa that may have been responsible for most important role of human evolution. Which would have led to the dispersion of human ancestors around the globe and the formation of the nationalities that we as humans are so proud of today.
Being human, we hold certain identifying characteristics that separates us from the rest of the animal kingdom. Modern day humans are able to walk upright and our bodies are able to withstand long distance running. More over, our heads are big and round, our jaws do not protrude out. Most importantly, we have face forward facing eyes. These are just certain physical characteristics that makes us human. Before us, we can see that our ancestors had primitive features, who were adapted to living in trees. In addition, the use of tools and other skills allowed early humans to adapt to new areas. The use of tools allowed for
...ary agriculture could store the bigger surpluses of grain easier than they did in the Paleolithic Age. They built houses to help store more food and also to help them grow more produce and food for their groups. Then they eventually had to build granaries to help store their seeds so they would not go to waste and ruin. The effects of having more food led to expansion of populations and communities developed specialized workers and more advanced tools. Last but
