What Makes The Most Sense You Me?

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

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).

In the Article “Redrawing Humanity’s Family Tree” by John Noble Wilford, describes how two different skulls challenge the theories of human origins and migrations. The Central African skull, that dates back to nearly 7 million years ago, was assigned to a whole new genus and species because of its apelike and evolved hominid species. The 1.75-million-year-old Georgian skull shows evidence that the first hominids may have been intercontinental travelers who set motion the migrations that occupied the whole planet. Finally a third skull was found that is the same age and shares a resemblance but, the size of the skull suggests that the brain was smaller than expected for H. erectus.

They were found in Africa 600-200kya, Asia 200-130kya, and European 800-200kya. They had big cranial capacity. They were using Acheulean tools. They led to the development of Neanderthal, the closed ancestor of modern human. They occupied the continents from 130-30kya. There fossils were excavated in Neander Valley, Germany in 1856 by C. Fuhlrott. Their cranial and postcranial features were close to the modern human. They had thin cranial bone, which the capacity was about 1500cc; barrel-chested; and short distal limb segment. Neanderthal climate had changed significantly to cold weather. According to Bergmann’s and Allen’s rule, populations living in cold climates tend to have larger body (trunk) sizes and shorter extremities than those living in warm regions (“Human Biological Adaptability: Adapting to Climate Extremes”). Neanderthals developed Mousterian Tool Industry with greater variety of more standardized tool type. The high quality raw material was occasionally used. They used tools for cutting plant material, meat, scraping hides, and sharping tools. Sometimes, shaped bone was used as raw material. Those tools were stable over time and space. There are some new evidences that the Neanderthal had showed the artistic expression. At more than 39,000 years old, the etchings rival in age the oldest cave art in Europe — and they are the first to be unquestionably done by a Neanderthal (Rodríguez-Vidal, J. et

This week’s video is about how humans evolved and their ancestor, homo erectus. The homo erectus were the first apes to be able to walk on two feet just like humans. They evolved from apes about two million years ago. Compared to apes, homo erectus had bigger arms, longer legs, and bigger brains. This made them really similar to humans. They even have the same skeletal structure as humans. Although they have similarities they also have differences. Unlike humans the homo erectus had smaller brains and slightly larger jaw structures.Although they had smaller brains they were able to think more advanced than apes. They also grew at a faster rate than humans. They are the perfect example of human evolution.

2. It can be concluded that both hominins and modern apes share flat face with forward facing eyes and molars present. The Phylogenetic Tree shows that the modern apes diverged from hominins. This implies that modern apes and hominins share a same ancestor, but early hominins did not evolve from modern apes. The closest relative of human (Homo sapiens) is Homo neanderthalensis. We share many characteristics, such as chain, large cranium and similar width of dental arcade to the length. One of differences is Homo neanderthalensis has Supraorbital bow, not human does not.

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

In this article “A New Kind of Ancestor: Ardipithecus Unveiled”, Ann Gibbon explains the discovery of an international Scientific’s team. This finding is the oldest known human ancestor skeleton and it has 4.4 million years. The Ardipithecus ramidus is the most complete earliest hominin found until now because it has the pelvis, hands, feets and most of the skull and teeth, it is bipedal and its features show a new early hominin, but is still being similar to other species.

There are so many questions and mysteries about humans came to be. The theory of evolution is the most popular theory people follow to help explain. Evolution tries to explain that life is constantly adjusting to its environment and making small changes through generations. It is believed that when life first started it all came from the same thing. Everything that is living on the earth right now has dna in common with humans. Scientists aren’t sure if there could have been multiple trees of life and one tree of life just happened to be the best and become the lone survivor, this is just another possibility that we can never be to certain of. Its believed that humans evolved from a species such as chimps. The chimp is what we have the most in common with when it comes to dna. We even have dna in common with plants.

To begin, Diamond talks about our evolutionary relatives, the apes. The history of humanity began in Africa about seven million years ago, when the African apes evolved into three categories. They evolved into gorillas, chimps, and humans. The earliest species of humans, Homo Habilis and Homo Erectus, became closer to modern humans in physical traits about 2.5 million years ago. One million years ago, Homo Erectus began to migrate out of Africa to Europe, Australia, Asia, etc. Homo sapiens first appeared around half a million years ago, having evolved from Homo Erectus. There is no perfect definition of Homo sapiens and therefore no exact date for when they first appeared. Still, scientists and anthropologists usually agree that Homo

here is an argument as to which Australopithecine gave rise to the genus homo. Evidence indicates that it was Australopithecus Sediba. The species lived 1.9 million years ago and greatly resembled Homo. According to Erin Wayman in his article Fossil Finds Complicate Search for Human Ancestor scientists still don't fully agree on where A. Sediba fits in the human family tree, but there is evidence to support it is possible ancestor. The study of two skeletons, on male one female, found in Malapa Cave in South Africa show that: the shape of the frontal lobe of the males brain is very similar to that of Homo. Also the pelvis had a mix of australopithecine- and homo-like traits leading scientists to believe they spend more time walking around and

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

Scientists and archaeologists knew Homo Erectus as the Upright man. Homo Erectus had many different physiological and behavioral characteristics in comparison to earlier Hominins. Fossils of Homo erectus additionally demonstrate that the species lived in various regions over the globe, including South Africa, Kenya, Spain, China, and Java. Furthermore, when analyzing the different physiological traits of Homo Erectus, we can take note that H. erectus had a comparable range of body sizes to present day humans. Their body and limb size implied that some of their adaptations such as gaining the ability to walk on two legs most likely occurred in large grass filled areas. In contrast to earlier hominin species who navigated their surroundings

The teeth of Homo erectus showed evidence of formation similar to that of ancient apes (“Homo Erectus”). Its other superior nature is believed to be its ability to use stone tools such as hand axes. There is also evidence of showing concern for their old ones and ensuring their well-being

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.
