Homo Erectus Human History

What evidence shows the changing from the early hominids to the modern humans? Throughout the human evolution body parts like legs and harms have changed for the better. By the early hominids being biped, meaning they are able to stand and even walk on two feet, it helped them to be able to do more things like getting around more and help with their tool making and hunting. A lot of the fossils discovered were found in the Great Rift Valley in East Africa, which contained many different lakes and small rivers. For many years researchers have been finding new species. These species have been named Australopithicus, robust australopithecines , Orrorin tugenensis, Homo habilis, Homo erectus, neanderthal, and Homo sapiens. These early

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).

This chapter does argue about the human history before civilization. It mentions how history courses and books leave out information about the human journey. Historians leave out Paleolithic and Neolithic eras.

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.

Human evolution: the study of how and why our human ancestors changed over millions of years.

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.

The evolutionary of human living has taken place over millions of years of geological time. It has evolved millions of generations, and billions of individuals. The human evolution is not understandable completely yet. Evolutionary change within a population can take place at different time and different rates, which yield different consequences. This process still taking place in the natural selection and human evolution. One species may be merged to the new species or developed to the next stage of the same species. Homo Habilis, Homo Erectus, Homo Heidelbergensis, and Neanderthals were the close ancestors of modern human, which developed from Australopithecus afarensis.

Evolution is the process of change of living organisms over a long period of time due to difference of environment or circumstances that was not prevalent before. These evolutionary mutations occur due to things such as a change of environment where what may have been shallow water has gradually gotten deeper and thus the organisms that inhabited that land had to change in order to remain living in that area without risk. This also relates to things such as storms that may alter the habitat of the previous land where what something may have eaten has changed and the organism was altered to match that environment. This then has an affect on the history of human evolution, humans and apes relate to a similar origin and were very similar many years ago and this is known as primate phylogeny. This Extended research task will go in depth with the origins of man and the relation between man and apes through primate

The main component of human evolution involves change. Because of the significant differences between each of the hominids and the ancestors of the chimpanzee determined by the categories of muzzle angle, Position of forearm Magnum, cranial capacity and finally the brain size to body weight ratio, provides exclusive data that the evolution of each of the species changed constantly over time. The phylogeny above was determined based on the data collected using the aspects above as the sole evidence on this subject matter. The time period in which they lived (refer to

According to Diamond, Human ancestors moved to Eurasia around 1 to 2 million years ago and after human fossils began to resemble modern Homo sapiens and archaeologists called that period the Great Leap Forward. According to “Human Evolution and the Great Leap Forward - By Advocate De Waal Lubbe,” Scientists have estimated that humans branched off from their common ancestor, with chimpanzees, about 5-7 million years ago. Several species and subspecies of Homo evolved and are now extinct. These include Homo erectus, which inhabited Asia, and Homo Sapiens Neanderthalensis, which inhabited Europe. Archaic Homo sapiens evolved between 400,000 and 250,000 years ago.

This chapter beings explaining the evolution of mankind. Prior to 11,000 BCE, all humans were equal. Due to our evolutionary past, we branched off from apes to humans and spread around the world. Nearly 4 million years ago, humans began their mark on earth in Africa. Jared Diamond compares human development on all seven continents about 13,000 years ago. Although many early humans were found primarily in Eurasia and Africa, over time they expanded and gained new territory. The early humans created tools as they evolved, and many became hunter and gatherers. Then, human history made a Great Leap Forward around 40,000 BCE. The Great Leap Forward was when the earliest humans created new technology and exciting innovations that did not exist previously

Neanderthal the most recent archaic human, who was introduced to this world between 300,00 and 100,000 years ago then after many years were replaced by humans between 35,000 and 24,000 years ago. Neanderthals inhabited Eurasia from the Atlantic regions of Europe eastward to Central Asia and from as far north as present-day Belgium southward to the Mediterranean and southwest Asia.” (www.britannica.com). Human populations that were very similar to Neanderthals lived in eastern Asia and Africa. Neanderthals lived in these locations because they had many limestone caves where they lived; limestone caves also preserve bones very well. “The name Neanderthal (or Neandertal) derives from the Neander Valley near

The most important innovation developed in the prehistoric period was the technological use of fire. The Homo Erectus species (approximately 3 million-500,000 years ago), were able to create a fire which allowed for several key pieces of our evolution to occur. First, these prehumans were able to now cook food as opposed to eating raw meat. This allows for more energy to grow the brain. The energy put forth to develop the brain causes Homo Erectus species the ability to create more efficient tools and survival skills. By cooking food, the Homo Erectus species were able to kill bacteria in the meat which would allow for less food related diseases. Their chances of survival were increased dramatically by this discovery. Second, a fire was used to keep warm.

Human evolution is the gradual process in which people, or Homo sapiens, originated from apelike ancestors. Scientific evidence, particularly in the form of fossils and secondary remains, show that the physical and behavioral traits shared by all people evolved over a period of approximately six million years. Humans are primates. Both genetic and physical similarities show that humans and the great apes (large apes) of Africa, chimpanzees (including bonobos, or so-called “pygmy chimpanzees”) and gorillas share a common ancestor that lived between 8 and 6 million years ago. The volume of fossils found in Africa suggests that most evolution occurred there and is likely the place of origin for early humans. This brings to fruition the “out of Africa” theory, also called the “single-origin hypothesis.”

Humans have existed on Earth for approximately 3.4 million years. The oldest known human ancestor is "Lucy," an Australopithecus. Over this extensive period of time, humans have evolved significantly. Homo Sapiens have grown from 3 to almost 6 feet (average), lost most of the body hair, became leaner and adapted to walking. Humans have come a long way, from Australopithecus to Homo sapiens, from living in trees to living in cities. Slowly, through hundreds of thousands of years, we mutated over and over again, natural selection ensuring that no destructive mutations continue. From the slow evolution, four distinctive species emerged and died out, each giving way to its ' descendant: Homo Habilis, Homo Erectus, Homo Sapiens Neanderthalesis, and Homo sapiens Sapiens.
