Recommended: Homo erectus short note
The Homo erectus was an early species of Homo and the likely descendant of the H. Habilis; the first Hominin species to move out of Africa into Asia and Europe. These were the Hominins that began to develop the characteristics behaviors that we see in living humans, that increasingly engaged intelligence and displayed adaptive flexibility, and the first depended on material culture. During the early Homo’s evolution, hominins began to colonize areas of the world outside Africa. The H.Habilis had a smaller chewing complex and a larger brain, and combined it gave the H. Habilis’s skull a rounder appearance. The H. Erectus has the anatomical characteristics from the distinguished H. Habilis. These Hominins collectively date to about 1.8 my-300,000 yBP. During this dynamic period of human …show more content…
The species has been classified in the genus of homo and has been named naledi.Scientist suggest they could have lived in Africa up to 3 million years ago and are insinuating that the naledi is a bridge between more primitive bipedal primates and humans
The skull of the naledi, shows similarities to the modern skull, The similarities include the pronounced brow and small teeth like the modern human. The skull of the naledi has a smaller brain cavity, then the modern human skull. The wrist and palm are quite similar to the modern human hand except the naledi has fingers that are slightly curved. The H. Naledi belongs between the H. Habilis, and H. Erectus, in the chronology of human evolution.
The remains were found in what is believed to be a burial chamber. The H. Naledi people appear to have carried individuals deep into the cave system and deposited them in the chamber –possibly over generation. This suggest that they were capable of ritual behavior and possibly symbolic
Chinese and Malaysian Homo Sapiens have very close features to the Neanderthal. The skull analysis of Neanderthals and Homo sapiens are usually considered more accurate if the entire skull is examined, rather than certain ...

Teotihuacan is an ancient Mayan city that can be found about 25 miles away from modern Mexico City. This large ancient city has several pyramids and the third largest pyramid is The Temple of the Feathered Serpent. The pyramid is hardly the most famous one associated with this archaeological site but it did gain popularity during the 1980s because of a series of discoveries of curious tombs located below the structure. There are over two hundred sacrificial burials that archaeologists believe were buried as a part of a dedication of the temple. The way that the bodies were laid out doesn’t have a specific meaning yet because the bodies seem to be grouped together in certain locations. The bodies are both from men and women, with the men having weapons and jewellery buried with them which probably indicated that they were warriors. Archaeologists believe that the temple may have been the resting place of a great leader as well thanks to a large deposit of liquid mercury that was
In recent years, the Homo Neanderthalensis were viewed as “subhuman brutes”, but are now seen as a different species from our own (Balter 2001). The Neanderthals were a branch of the Homo genus that evolved in Eurasia at least 200,000 years ago (Fagan 2010). The first Neand...
The species A. afarensis is one of the better known australopithecines, with regards to the number of samples attributed to the species. From speculations about their close relatives, the gorilla and chimpanzee, A. afarensis’ probable social structure can be presumed. The species was named by Johanson and Taieb in 1973. This discovery of a skeleton lead to a heated debate over the validity of the species. The species eventually was accepted by most researchers as a new species of australopithecine and a likely candidate for a human ancestor.
...oling climate and slowly evolved into Homo erectus, and then Homo erectus was affected by sexual selection, the split of their population, and their new necessary diet. They, in turn, slowly evolved into modern Homo sapiens. Natural selection, sexual selection, and genetic drifts all affected these species, and what took them to evolve into us, modern humans.
Research shows that the Neanderthals had a “protruding jaw, receding forehead, and weak chin.” (Ansering Genesis) The average brain of a Neanderthal was slightly larger than a modern humans brain. It is also stated that this specific species generally was larger in body size. The Neanderthals also tend to live mostly in colder climates. Researchers and paleontologists found many remains left by the Neanderthals, which include bones and stone tools, found in Eurasia, Western Europe to Central, Northern, and Western Asia. “Neanderthals (or Neandertals) are our closest extinct human relatives. There is some debate as to whether they were a distinct species of the Homo genus (Homo Neanderthalensis) or a subspecies of Homo sapiens. Our well-known, but often misunderstood, fossil kin lived in Eurasia 200,000 to 30,000 years ago, in the Pleistocene Epoch.” (Live Science) The Neanderthals had a very similar appearance to human, although they were “shorter and stockier with angled cheekbones, prominent brow ridges, and wide noses.” (Live
Most of their evidence comes from the fossilized bones of Neanderthals and Cro- Magnons, or modern man’s ancestors (Shreeve, 150). There is a definite difference between their bone structures, and it may be a significant enough difference to divide them into species. There is a set of traits that distinguishes Neanderthals. Their general proportions are short, robust, and strong. Males and females of all ages have thick bones, and very pronounced muscle and ligament attachment sites. They also have distinct facial and cranial features. They have a large skull with no chin, a significant brow-ridge, and a large nasal opening (Shreeve, 49-150). They have large brains, around 1400cc, that protrude in the back, causing an occipital bun in the skull (Lecture, 4/19). Cro-Magnons on the other hand look more like humans do today. They are more slender and not as muscular, with chins and rounder skulls with slightly smaller brains among other traits.

“The scientific study of how humans developed did not begin until the 1800s in Europe. Until that time, people relied on religious explanations of how humans came into existence. Starting in the 1500s a scientific revolution began to sweep Europe. Thinkers started using scientific methods and experiments to try to better understand the world and the creatures living in it. Eventually these methods were turned to the question of human origins” (The Nature Of Human Origins, 1). Earth made it possible for species to change over time because Ancient Earth provides ability to plenty of time.The Homo Sapien a is very complex creature. The species started off very simple by living in caves and surviving with little food and then later evolved into a species that were able to do many more complex things. The first species was Sahelanthropus tchadensis They were one of the most simple humans in that time period and on. They had very small skulls compared to Homo Sapiens today and their motor skills were just the same. We have evolved and changed for the better both mentally and physically. The Evolution of Homo Sapiens started off simple, such as the Neanderthals, and now we are the most advanced species to ever walk the planet so far.

The members of the Homo genus possess a combination of unique features that distinguish them from other related species. At the time that each respective species was alive, they were able to walk upright on two legs, use their large brains for the benefit of their species, and could thrive in many geographically and climatically diverse areas of the world. One of the most mysterious quandaries in science is how the lineage of the Homo genus became so different from their primate relatives. Bipedalism, brain size, and location diversity all have a common link that may explain this difference – dietary evolution allowed humans to adapt to their surroundings, and in turn, become a more advanced species. The Homo diet evolved in relation to food availability and nutritional necessity. With the ability to maintain a proper diet, the species of the Homo genus were able to flourish and advance toward the development of modern Homo sapiens.
Their faces also consist of big arching browridges just above their eyes (Stanford 302). Throughout the human evolution fossils have been found and each bone discovered demonstrates how the early hominids to the modern human features have changed. Each bone showed off different stories and new facts. Even the inner ear bone has changed in shape and in size throughout the early hominids. Over time the littlest things have changed but it seems like it helped surviving better, by helping to be able to be biped and tool making.
The increase in brain size may be related to changes in hominine behavior (See figure 3). The third major trend in hominine development is the gradual decrease in the size of the face and teeth. According to the Microsoft Encarta Encyclopedia ’98, the fossil evidence for direct ancestors of modern humans is divided into the category Australopithecus and Homo, and begins about 5 million years ago (See figure 1). Between 7 and 20 million years ago, primitive apelike animals were widely distributed on the African and, later, on the Eurasian continents (See figure 2). Although many fossil bones and teeth have been found, the way of life of these creatures, and their evolutionary relationships to the living apes and humans, remain matters of active discussion among scientists.
Throughout the long winding road that is human evolution; many species have helped shape who we are today. There was the early Australopithecus africanus which began to walk bipedally-upright with two feet and the Homo habilis which drastically developed the construction of handmade tools. But there is one species who is to be credited for the most critical advancements in human evolution; Homo erectus. Not only did Homo erectus advance us the most biologically, but also the most geographically.
