These stone tools were probably used for chopping, cutting, piercing, and pounding meat. Possibly they were scavengers. The head and face were “primitive” with the forehead sloping backwards and prominent brow ridges.
Leakey believes their tool craft may have actually declined, during the erectus period. Fossils: Jaws, teeth, and an occasional skull cap and thighbone have been uncovered.c. But there were differences.
Apart from this anatomical evidence, we have another common sense reason for doubting erectus’ ability to speak. Again, where evidence is Injection Molding Barrel thin, speculation abounds. That means erectus had less muscle control in his rib section.
Locations: Europe, India, China, Southeastern Asia, and Africa.c. Those muscles along with their supporting nerves control breathing. to 1100 c. That’s a lot of tools. Like the australopithecines, erectus displays noticeably large thigh bones and a small pelvis. for Homo habilis and 1400 c. Those early fossils from Africa may need to be reclassified in a separate category from the later ones from Asia. They say he is human. How they got their meat remains a mystery. That’s a long, long time without improvement.
Did Homo erectus evolve into modern humans? Or were they a breed apart? Scientists disagree; there’s no clear proof either way.”
From Africa and China, we find solid evidence that erectus was using fire. Meat was evidently an important part of erectus’ diet. Richard Leakey tells us that twenty thousand stone tools have been found associated with erectus.” Their weight and height would place them in the top 17 percent of modern human males.
Johanson describes Homo erectus as “tall, thin, and barrel-chested. Apparently, erectus could not talk. And that is a distinction of considerable importance. for australopithecines, 650 c. Large potato-shaped hand axes, along with picks, and long-edged cleavers are the basic utensils of Old Stone Age technology, otherwise known as the Acheulian tool industry. Contrast that to the accomplishments humans have made in the last two hundred years. compared to 350 – 400 c. But we don’t find any.
Their bones were considerably heavier and more massive than those of modern man. One million years ago at Swartkran, erectus was probably cooking food and/or using fire to keep predators away.c. It would mature at thirty-two ounces compared to forty-five ounces for an adult human.
Brain Capacity: Donald Johanson says 850 cubic centimeters to 900 c. They were designed for mobility.
The Acheulian technology was a stagnate technology. But something is missing.
In contrast to Johanson’s view, Richard Leakey believes Homo erectus was a little stockier than the average human today. Whether they could make it is still questionable. It is thought that erectus’ brain weighed around seven ounces at birth. No spear, dart, or arrowhead has surfaced.
In many ways erectus seems almost like us. MacLarnon, erectus probably lacked the number of cell bodies which we have in our spinal chord. At Zhoukoudian, a Peking site in China around 500,000 years ago, a series of ash layers leads anthropologists to believe erectus was responsible for these ancient hearths. But hunting weapons are not among them.
According to Ms. Remarkably similar erectus bones and tools have surfaced in Africa, Asia, and Europe. Walking and running came naturally for them; however, such dexterity came at a price. He comments, “Some of the later examples of the technology appear simple and crude compared with some earlier material. There’s a major difference between erectus and sapiens in the thoracic region. Based on reconstructed skeleton of a twelve-year-old male, Johanson believes erectus had a body shaped like many African groups today.Homo erectus lived from an estimated 2,000,000 down to 100,000 years ago. In 1984, a well-preserved almost complete erectus was discovered in Kenya.
Erectus made and used tools. It didn’t even adapt to local conditions. Erectus’ narrow pelvis severely limited the size of its brain at birth. If they were discussing and comparing their stone techniques, that should be enough to spark an occasional improvement over a million years or so. The same argument that arose earlier with Australopithecus afarensis and Homo habilis surfaces again with Homo erectus.c for humans.
We find evidence that they were using their hand axes for cutting and carving wood and meat. Others believe erectus is an early form of sapiens. Richard Leakey claims 900 c. Finely controlled breathing is an essential requirement for speech. It didn’t improve over time.
In this respect, Homo erectus is physically closer to an ape than it is to modern humans. Java and Peking man are included among Homo erectus.
Did Homo erectus talk? Probably not, concludes anthropologist Ann MacLarnon. His face protrudes less than Homo habilis, but hot as flat as Homo sapiens. The chin was present but poorly developed. The vertebral canal in Homo sapiens is twice as wide as it is in erectus. And as Johanson points out, “There is the troubling matter of a tool industry that didn’t change for a million years.
Where should we place Homo erectus in the scheme of things? The experts disagree. Height: 5 feet 2 inches to 6 feet; Weight: 100 to 150 pounds. The cultural traits of language, funerary rites, and art are all absent.. And the brain remained proportionally smaller than sapiens’. Paleontologists question whether erectus is one or more species. Incredibly enough, we find the same hand axes, picks, and cleavers in Africa, Europe, and Asia.c. And their facial features included low sloping foreheads and heavy curved brow ridges.
Those qualities combined to make this species more athletic than we are today
