Evolution Of Human Culture Developed Based On Our Environment

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.

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.

The fossils of Home habilis species were discovered by Dr Louis Leakey in Tanzania. Among the distinguishing characteristics include the increased cranial size as compared to its ancestor, the africanus. The fossil also indicated an increased grip hand size due to size and type of hand bones. The other feature is that the fossil indicated a reduced size of the teeth. The evidence showed that the ancestor had molars longer instead of wider. As a result of the increased grip, it was concluded that this human ancestor used tools for survival. Homo habilis means the handy man because the scientists thought the species to be the first to make tools (Denis, 2008).

The Out of Africa Theory is a widely renown theory describing the origin of the human race and their early dispersal throughout the world. According to this theory, humans have a monogensis, or a single and common origin; Africa. The concept was first introduced in 1871 by Charles Darwin but was deliberated for years until further studies of mitochondrial DNA and evidence ”based on physical anthropology of archaic specimens” was added.

The complete history of human evolution is a long-standing mystery scientists have yet to fully figure out. The topic typically focuses on the evolutionary trajectory of primates, which over the course of millions of years, has lead to the appearance of anatomically modern humans. As you can imagine, piecing together beyond ancient history, involves the combined prowess of many scientific disciplines, and once in a while, a curveball may confuse even the most methodical anthropologists. Other times, a rare “ah-ha!” moment is encountered, which can shed light on the complex timeline of Homo Sapiens.

Homo rudolfensis was found in 1986 by V.P. Alexeev . 2.4-1.8 Million years ago. Rudolfensis maybe one of the first Homo Species and can maybe be traced back to kenyanthropus platyops. Many believed at first glance Homo erectus was close to Homo habilis because they shared many of the same features, were found near each other and dated to around the same time to 2.4 to 1.8 million years ago for habilis 2.3 to 1.5 million years ago for rudolfensis. Both are put under scrutiny because many believe that due to the case of them having longer faces and bigger molars that they are from Australopithecus and should be placed with them.Making them an australopithecus would mean that it had the largest brain

One of the first humans, or hominids, was discovered to be living in the eastern and southern regions of Africa approximately three to four million years ago. They were named the Australopithecines, which means “southern ape-men.” These bipedal hominids developed basic stone tools. Another kind of hominid known as the Homo habilis, or “handy humans,” was discovered in Africa by Louis and Mary Leakey in 1959. The Homo habilis had a significantly larger brain than the Australopithecines. Equipped with a more complex brain, these hominids were able to not only walk upright, but also to gather various nutritionally beneficial foods such as seeds, nuts, and meats. But the Homo erectus,

Our world as we know it, is full of missing puzzle pieces when it comes to completing the picture of how human kind truly came to be. For years and years talented fieldworkers have been working all over the world to try and collect all of these missing pieces. Slowly over the years an increasing amount of body and fossil records are helping us better understand when, where and how hominins came into and left existence. There have been many discoveries between the Australopithecus Afensis and more recent discoveries with very human like features like the Homo Erectus. The discovery of the Australopithecus Sediba is seen as a bench mark halfway point in our evolutionary time line their fossil discovery gives us insight on how they would have lived, what they could have looked like and how they are presumably related to humans.

Originating in Africa, the history of early human beings can be traced to nearly 1.9 million years ago with the species Homo erectus; which were described to have a large body, a thick skull, a strong jaw, and 725 cubic centimeters of brain capacity. However,

Understanding human evolutions is important for identifying the stages of humanity and for understanding how our societies have developed. When most of us think about human

Due to the constant battle between similarities and differences between different species of the genus Homo, one major concept to retain from this article is the fact that ‘later’ hominins are not just simply scaled-down versions of older hominins. Evolution and adaptation is not a simple straight, perfect line that can be simply traced. It is a complex, non-linear progression, full of error and imperfect

Human evolution is the process of change by which people originate from apelike ancestor. Behavior traits and scientific evidence show that people are originate from apelike ancestor. Humans first evolved in Africa, and much of human evolution occurred on that continent. The process of evolution involves a series of natural changes that cause species to arise, adapt to the environment, and become extinct. All African early hominids—small australopithecines as well as the very tall Homo erectus have absolute body breadths within the modern human tropical-subtropical range; variations in relative body linearity is due almost entirely to variations in stature (Ruff, 1991).All species have originated through the process of biological evolution. Scientists classify each species with a scientific name. For modern humans, they are classified as Homo sapiens. Physical and genetic similarities show that the modern human species, Homo sapiens, has a very close relationship with the apes.

In the greatest debate of anthropology lies the all consuming desire to know where we as humans come from. Who were our ancestors and what made them so different from us? It is debated if A. africanus or Australopithecus afarensis is the direct ancestor of the genus Homo. Through critical evaluation of the features of the skeleton, dentition, and use of bipedality, it is evident that A. africanus is a direct ancestor to modern humans while possessing features from both humans and hominins.

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.

Human evolution according to research started over 6 million years ago. The outcome of the evolution process is the current human beings. Scientific studies have revealed over the years a remarkable affinity between the chimpanzees/Apes and human beings. Even though this reality is not a definitive prove that human beings evolved from apes, it does show that the human beings are in one way or another related to other primates. Scientists suppose that the humans and the primates shared a common ancestor. The subject of what makes humans what they are and their origin has been the exclusive purpose leading to many scientific studies globally (Coolidge & Wynn, 2011). Studies believe that Africa was the origin of evolution millions of years ago. Fossil remains have been discovered in different parts of Africa as well as other regions of the world. Different hominins have been discovered around the world in the last 1 million years. Thus, the different discoveries have led to comparisons between the various species of hominins to clarify on their similarities as well as differences. This essay seeks to explain whether they were distinctively different species or regional versions of the same species.
