The Evolution Of The Homo

Homo erectus was first found in Africa and the fossilized remains dated 1.8 and 1.0 million years old. The Homo erectus traits are very similar toward the modern human traits. Homo erectus brain size was smaller than the Homo sapiens. Homo erectus had a brain size of approximately 650 cc and Homo sapiens had a brain size of approximately 1251

H. erectus then traveled to other continents from there about two million years ago. These pre-modern humans that were spread out all over Asia and Europe were then believed to evolve into H. sapiens autonomously. This theory helps scientists to explain why there are genetic and phonotypical differences between “races”, such as skin color, hair color, facial features, and so forth. It additionally explains why we have some evidence of H. erectus fossils being in places other than Africa.

In the quest to explain human origins it is necessary to find a species that bridges modern man (Homo sapiens) with the apes. To fill this gap evolutionists have set forth Homo erectus, who lived approximately 400,000 to 1.6 million years ago (Johanson and Shreeve1989). Although the distinctions are somewhat vague, below the neck, Homo sapiens and Homo erectus are practically Identical and Homo erectus was responsible for pioneering the use of standard tools (such as the hand axe), big-game hunting, and the use of fire (Johanson and Shreeve1989).

Throughout history, humans have gone through evolution and adapted to new environmental changes to survive. One would wonder how they manage to survive and dominate the Earth for so long. A possible ancestor to humans known as Homo erectus (sometimes called Homo ergaster) may have been the reason why humans have been so successful in survival today. Homo erectus has been a live about 1.89 million years ago to 143,000 years ago. He was the first hominid to leave Africa and was also known as Turkana Boy in Africa, Peking Man in China, and Java Man in Indonesia. H. erectus gained his name for being able to stand upright or have an erect posture. One can say that they are the pioneers of the Old World because they were the first hominid to master the use of fire. Once evolution took place, they began developing larger skulls. This allows their brain to grow larger, thus becoming even more intelligent. Because of this, H. erectus became very successful in creating cultural technologies that allowed them to adapt to new environmental opportunities. Through speculating this

In the Neander Valley near Dusseldorf, Germany in 1856 a group of quarrymen discovered the remnants of a skeleton. In a limestone cave they found 16 pieces of bone including a skull. Thinking that the bones belonged to a bear the quarrymen gave them to a local teacher named Johan Karl Fuhlrott. From him the bones found their way to other scientists. It was eventually determined that they were an ancient human relative. (Szalay, 2013) At first scientists weren’t sure what they’d found: some claimed it was the remains of Mongol horsemen, others thought they were deformed Homo sapiens. It wasn’t until 1864 that an Irish Geologist named Dr. William King came up with the name Homo neanderthalis describing the location of where the bones were found, Thal is an older spelling of tal which is the German word

One of the earliest ancestors of homo sapiens that are known of is the tchadensis which is a member of the genus Sahelanthropus. The S. tchadensis is a primitive human that lived about 7 million to 6 million years ago, it is believed that they lived in areas that would require walking on two feet such as grasslands, as a result the S. tchadensis had the ability to partially walk on two feet. As time went by the S. tchadensis evolved into the tugenensis, which is a member of the genus Orrorin. The main difference between the S. tchadensis and the O. tugenensis is that the O. tugenensis developed two femur bones which are used for walking on two feet, the O. tugenensis was around from about 6 to 5.8 million years ago. The third genus in human evolution came into existence about 5.8 million years ago and was named Ardipithecus, this genus has two known members kadabba and ramidus.

habilis are hominins living in 1.8 mya and H. erectus are hominids living in 1.5 may. However, H. erectus is much taller and smarter than H. habilis. The scientists think the reason why it will happen is that maybe H. erectus begin to eat meat. Some research shows that H. erectus at least eat meat by scavenging. The consumption of meat enable H.erectus to acquire high quality protein and thus their brain size can expand and height grow tall very fast. In additional, there are some clues that H. erectus found in Zhoukoudian are able to use fire because the remain of animals and stone tools are burned. Therefore, H. erectus are likely to cook their food before they ate. Cooking food can improve the digestibility of food so that h. erectus can get better nutritional outcome. Because the better food can ensure to meet the nutritional need of expansion of brain, H.erectus are becoming more and more clever. As a result of that, H.erectus can use the tools and fire more effective and they can get more opportunities to adapt the environment, hence H.erectus can successful become the earlier

There are many known species of hominids that lived before the first known species that belongs to the genus homo. These hominids, while not in the genus homo, are known to be some of the earliest known ancestors to modern day primates, including humans. The earliest known hominid is sahelanthropus tchadensis which lived roughly seven million years ago and is an ancestor of modern day

1. The thing that distinguishes Homo sapiens from the other Homo genus’, would have to be their ability to think and produce symbols that enabled them to communicate with one another. Homo sapiens were the first to bury their dead, and are the closest “extinct cousins of modern- day humans”. Homo habilis , which was the first (“tool – making human”) to make the first stone and bone tools, which were made to skin and chop animal flesh. Homo habilis made tools not weapons, they were scavengers who ate solely off the land. They gathered fruits , grains , and whatever else they

Culturally, the Homo erectus was very successful compared to the other hominids because they had strong families. They multiplied and produced strong offspring as well. Aside from strong famlies, the Homo Erectus' utilized fire which made them sucessful as well. They used fire to stay warm, to cook their meats and other foods, and it was a tool to protect them against predators as well. The biology of Homo Erectus consists of a reduced size in the face, which includes their jaws and teeth. They also have a much bigger body and brain than Homo Habilis'. The Homo Erectus have pretty short arms and fairly long legs. The Homo Erectus had great access to animal food sources and had the ability to hunt, therefore they had sufficient protein in their

Members of the Australopithecus family had several characteristics that were distinctively unique. Australopithecus fossils exhibited both apelike and human characteristics. This combination of traits led researchers to the assumption that Australopithecus must be an ancestor of the genus Homo, since they share many traits this led to their classification as hominids.

Homo Erectus has been argued to be the first hominid to successfully migrate out of Africa, Home Erectus had a brain size approaching that of modern humans, averaging just under 100 cubic centimeters, his brain actually reached the lower limit of modern human brain size, Erectus was also the first human species to have a wide, fleshy nose, his face was flat and his skull had prominent ridges over the brow. his shorter arms were a departure from Homo habilis and Australopithecus, indicating that tree-climbing ability had finally been lost, His longer legs were better suited to running and walking long distances- a trait that doubtless helped him migrate into Asia, ranging from 4 foot 9 to 6 foot 1 are from 88 to 150 pounds, Homo Erectus was the first ancestor to approximate modern humans in size, in fact, except for the brow ridges and smaller brain. homo erectus was perhaps the fisrt species that we might consider to be essentially human.

There is no denying the fact that fossil records show an excellent representation of species of the past. Details of human evolution can also be identified and new discoveries are being found. Homo naledi is the most recent discovery within the Homo genus. This new discovery could potentially be a very important key in studying the evolution of the human species.

Hominids with a brain absolutely and relatively larger than that of the australopithecines appeared about 2.3 million years ago. These hominids are classified in our own genus: Homo. The earliest species to appear was the Homo Habilis. It was the first of our ancestors to show a significant increase in brain size and also the first to be found associated with stone tools. These characteristics resulted in this species’ placement into the human genus, Homo.
