According to the film, Birth of Humanity: Becoming Human—Unearthing Our Earliest Ancestors, NOVA depicts that the Homo erectus was the middle ground of developing from apes to humans, using the Turkana boy as a reference. The Turkana boy was the earliest human skeleton, yet he still had a primitive upper body and a human lower region. At five feet and three inches, he is eight years old and still growing, based on his teeth and skull evaluation. His brain was larger than a chimpanzee but smaller than the modern human. With the creation of stone tools, it proved that the Homo erectus was capable of decision-making and understanding the stone’s properties. In addition, it would allow the Homo erectus to gain food by using the tool to his or her
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...
Human characteristics have evolved all throughout history and have been manipulated on a global scale through the use of science and technology. Genetic modification is one such process in which contemporary biotechnology techniques are employed to develop specific human characteristics. Despite this, there are a countless number of negative issues related with genetic modification including discrimination, ethical issues and corruption. Hence, genetic modification should not be used to enhance human characteristics.
Australopithecus afarensis existed between 3.9 and 3.0 million years ago. The distinctive characteristics of A. afarensis were: a low forehead, a bony ridge over the eyes, a flat nose, no chin, more humanlike teeth, pelvis and leg bones resembled those of modern man. Females were smaller than males. Their sexual dimorphism was males:females; 1.5. A. afarensis was not as sexually dimorphic as gorillas, but more sexually dimorphic than humans or chimpanzees. A lot of scientists think that Australopithecus afarensis was partially adapted to climbing the trees, because the fingers and toe bones of the species were curved and longer than the ones of the modern human.
When looking at Africa, it is believed that the first H. erectus seems to have evolved here. This theory developed based on the fact that all of the previous hominins to make an appearance were also in Africa, so it stands to reason that the evolution from those early hominins to H. erectus would have occurred in the same location. That being said, evidence also shows that after H. erectus made his debut in Africa, he quickly migrated to other parts of the world, as fossil remains have also been found in Europe and Asia around the same time period. And, it is through the migration of H. erectus, that fossil remains show the greatest differences in physicality to one another. Anatomically, African H. erectus had a brain and brain case similar in size to previous hominins, however, smaller than “average” skulls were found showing that there were some African H. erectus with smaller skulls which may have been women (indicating sexual dimorphism) or children/youth, the skulls also had fairly large browridges with thin skull bones (typical of East African H. erectus, ve...
The Neanderthals are an extinct species of human that lived in ice age Europe between 120,000-35,000 years ago. This species is known for their receding forehead and prominent brow ridges. We know this species as the uncivilized or unintelligent person or group. Neanderthals are often portrayed as “unintelligent cavemen in animal-skin clothing.” Scientists’ first thought the Neanderthals’ were subhuman, but that thought is beginning to change. The original name given to the Neanderthals when they were first discovered was ‘Homo Neanderthalensis’ and they were considered to be an ancestor to modern humans. “Forty-four years after this biased classification, Neanderthals were reclassified as a human subspecies Homo sapiens Neanderthalensis and
Most of their evidence comes from the fossilized bones of Neanderthals and Cro- Magnons, or modern man’s ancestors (Shreeve, 150). There is a definite difference between their bone structures, and it may be a significant enough difference to divide them into species. There is a set of traits that distinguishes Neanderthals. Their general proportions are short, robust, and strong. Males and females of all ages have thick bones, and very pronounced muscle and ligament attachment sites. They also have distinct facial and cranial features. They have a large skull with no chin, a significant brow-ridge, and a large nasal opening (Shreeve, 49-150). They have large brains, around 1400cc, that protrude in the back, causing an occipital bun in the skull (Lecture, 4/19). Cro-Magnons on the other hand look more like humans do today. They are more slender and not as muscular, with chins and rounder skulls with slightly smaller brains among other traits.
In class we watch a clip called “Journey of Man” and basically the all over view of this movie was about a man named Spencer Wells and his team of scientist researching for approximately 15 years of investigating to find out our family history. They believe that they have discover some life changing information. They had this discovery for a while now but that needed time to gather up all of the facts from their research. This information that they have could transform our view on the world. They have revealed some type of time machine that has allow them to see back in ancient history. For that past ten years this man and his team have been using this time machine to gather all types of different information about the past history. This information came for just once source, blood. Many people views it as and gift from the past, but to scientist it carries the past and has a unique story behind it. A time machine hidden within us.
The first group of primates was the Ardipithecus group. They were the earliest humans closely related to other primates. The Ardipithecus group evolved in Africa and took the first step upright on two feet. Sahelanthropus tchadensis was the first human species to ever walk the earth. They were the building block of more complex species to come. There were many species that started the human race such as the Orrorin tugenensis. This species was nicknamed the Millenium Man and live 5.8-6.2 million years a...
Since the discoveries of Charles Darwin and other nineteenth century explorers, humans have created an analogy of the evolution of our own species. This view of our evolution is often represented by an all-too-familiar branching tree. Recent studies, however, suggest that this interpretation should be replaced with a map of human derivation in the form of an interwoven “tapestry.” These lineages would come together in kinships over time (Finlayson). Two recent studies have proved that Neanderthal DNA is still present in modern human keratin, the protein that helps produce skin, hair, and nails (Yong). Today, there is much uncertainty in the work of anthropologists. Any new discovery in paleontology, large or small, is likely to change our big understanding of human evolution.
Humans are extremely complex and unique beings. We are animals however we often forget our origins and our place in the natural world and consider ourselves superior to nature. Humans are animals but what does it mean to be human? What are the defining characteristics that separate us from other animals? How are we different? Human origins begin with primates, however through evolution we developed unique characteristics such as larger brain sizes, the capacity for language, emotional complexity and habitual bipedalism which separated us from other animals and allowed us to further advance ourselves and survive in the natural world. Additionally, humans have been able to develop a culture, self-awareness, symbolic behavior, and emotional complexity. Human biological adaptations separated humans from our ancestors and facilitated learned behavior and cultural adaptations which widened that gap and truly made humans unlike any other animal.
A civilization is the starting point of a society. Civilizations have existed for millions of years and are the basic unit of structure for a society. Civilizations were the base of great societies such as Egypt and Rome. If not for civilizations these societies would not have flourished or even existed.
This era of early tool development took place during the Lower Paleolithic, and was known as Oldowan tool tradition. Anthropologists suspect that a feedback loop between brain size, behavior, and language began to develop during the time of Homo habilis, due to a proposed correlation between the gradual increase in brain complexity and size as well as the development of more complex cultural aspects of their society, such as the various tools developed during the era of the species habilis. The arrival of Homo erectus, about 2 million years ago, marked another noteworthy progression of biological and cultural adaption, as well as further evidence supporting the feedback loop
“The common outcry, which is justly made on behalf of human rights - for example, the right to health, to home, to work, to family, to culture - is false and illusory if the right to life, the most basic and fundamental right and the condition of all other personal rights is not defended with maximum determination.” -- Pope John Paul II
Throughout the long winding road that is human evolution; many species have helped shape who we are today. There was the early Australopithecus africanus which began to walk bipedally-upright with two feet and the Homo habilis which drastically developed the construction of handmade tools. But there is one species who is to be credited for the most critical advancements in human evolution; Homo erectus. Not only did Homo erectus advance us the most biologically, but also the most geographically.
Mankind’s origin is from God through creation. The Bible tells us in Genesis chapter 1 verse 27; So God created man in His own image, in the image of God created He him: male and female created He them. The Bible also says in Genesis chapter 2 verse 7, And the Lord God formed man of the dust of the ground and breathed into his nostrils the breath of life; and man became a living soul.
