Australopithecus Afarensis Species and Their Existence
Humans are a species of hominidae. A hominid is any one of a family, hominidae, of mammals that includes humans with their extinct ancestral forms. Hominids evolved from each other. Humans have evolved over the millions of years from the first hominid. One of the hominid species that humans have evolved from is the Australopithecus Afarensis. A classification of an Australopithecus Afarensis is a Southern Ape. This species is a vertebra and a primate. The Australopithecus Afarensis have similar characteristics with humans, homosapeaons, while having their own ape like characteristics and way of life. This species was discovered in 1974 and was formally named in 1978 after a wave of fossil discoveries were found. These fossils did not match any known fossils or families, so the species was given the name Australopithecus Afarensis from the location they were found. One of the famous fossils found in this wave was named “Lucy”. The average height for males of this …show more content…
The bones of the Australopithecus Afarensis is one like humans have not seen yet. Evidence shows that they walked upright on two feet, but researchers are still not certain on how the species walked. Their footprints, shape of the pelvis, the curve of their spine, and the anatomy of their knee indicate that the species walked on two legs. This is one similarity of the Australopithecus Afarensis to humans, along with their body shape, use of thumbs, and the shape of their face. There are also some differences between humans and the Australopithecus Afarensis. Their stride as they walk is much different to that of a humans because of their short legs, long arms, curved fingers and toe bones, and the structure of their hip. Australopithecus Afarensis have large canine like teeth. The Australopithecus Afarensis pelvis bone is much more humanlike than

    Similarities Between Humans And Neanderthals

    Homo sapiens and Homo Neanderthalensis, the scientific name for modern Humans and our closest extinct relative the Neanderthal. These two primates from the “Homo” genome from which Humans and Neanderthals evolved from to come become modern Humans. These two species have coexisted with each other in the past, and even battled for survival as humans expanded across the world. Humans and Neanderthals also interbred with one another mixing the DNA of their offspring and some of this DNA from Neanderthals can be found in Humans. Some of the adaptations Humans possess came from this interbreeding, which helped humans spread from Africa to Eurasia, and adapt to colder temperatures (Moore, William). Although Humans and Neanderthals are very close relatives both have many factors which differentiate the two species one another.…

    The Human Family Tree

    Homo erectus is the oldest modern human life body proportion in relation of longer legs and shorter hands comparing to the past Homo groups. Eugene Dubois discovered Homo erectus in 1891 in Northern, Eastern and Southern Africa. It’s estimated to be 1.8 million years old. These features are considered adaptation to a life lived on the ground and the ability to walk for long distance.…

    Hominin Evolution Theory

    Evolution shapes certain characteristics which can be shared by many species of a certain organism. These traits can be related to the four evolutionary trends of hominins: bipedalism, dental change, cranial capacity and material culture. (Gonzalez, pwpt) The three anatomical characteristics of skull one are the teeth and jaw are smaller, the projection of the face and jaw is less than previous hominins and the cranial capacity increases by elongating. The dental change suggests a change in diet from being herbivores to being omnivores because of environmental changes. The changes in the prominence of the face and jaw is due to evolution choosing the species to be bipedal. The cranial capacity increases which allows the capacity to have a materialistic culture. The slight projection of the face and jaw, a large cranial capacity and large nasal feature are the anatomical characteristics of skull two. Evolution chooses the slight projection of the face because the species is bipedal. The large cranial capacity allows for the culture of Homo sapiens neandertalensis to become more materialistic. Also, the increase of cranial size provides the capacity to create and use tools. The large nasal feature on the skull is an evolutionary adaptation due to the cold environment the species lived in. The anatomical characteristics of skull three…

    Essay On Sahelanthropus

    Hip support came late around 1.95 million years ago with the size and also the broad shape of these hip bones of that of Homo erectus are very similar to those of modern humans, this shows that this early form of human species completely stopped climbing to take on full bipedalism as way of getting around. Its till 1.9 millions years ago that early specie of man became fully bipedal with the pelvic and also the thigh bones from the specie of Homo erectus are similar to those of modern humans, this showed that Homo erectus would be able to walk long distances. This ability aloud a very big advantage during this period in time. Then finally around 1.89 million years ago we see that Homo erectus had long thigh bones that allowed them to walks faster and great lengths than earlier humans (Smithsonian…

    Human beings belong to the species of Homo sapiens and are of the genus homo. Because of their mental capacity and development, speaking capability, they have been distinguished from other animals. Human beings are also the only creatures that can think on 4 levels which are emotions, beliefs, facts and ideas. We have them. We use them every day. Emotions are used on a daily basis. We can go from being happy to being angry in seconds. I believe emotions are what makes us humans.…

    Ardipithecus Ramidus

    Ardipithecus ramidus was around 4.4 mya. They were located in Ethiopia. Their appearances included a skull, teeth postcranial bones found. Although, they still have small brains. Their femur and pelvis made it possible for bipedalism. The shape of their body gives it a helpfully way for them to be bipedal. The centrally placed foramen magnum allows for them to stand a bit straight. Also, the pelvis was bowl shaped and there was a show of lumbar lordosis. Although, they still had longer arms compared to modern humans. Their foot also showed a bit of difference, rigid, abducted hallux allowing to grasp which gives an idea of them holding on to being arboreality. They still had curved phalanges but they no longer knuckle-walking. (Flower 2016).…

    What Were Primarily Ancestral Characteristics

    Each characteristics of species defines their lifestyle. From Australopithecus afarensis having canine tooth projected beyond the chewing surface and having canine diastema depicts the possibility of species having raw carnivorous food. Throughout time, species started exploring more food and started cooking leading to large molars to chew their food. The width of the dental arcade helped later species. The skull and vertebral attachment shows how species evolved to have a bipedal lifestyle. The skull and vertebral attachment index is low for gorilla gorilla as they walked using their all four limbs where as it gradually increased from Australopithecus afarensis where the index increased as they started walking…

    Primate Evolution Essay

    Both of these species are members of the Hominoid family. Although some people may find it difficult to accept, Apes have been said to be the ancestors of humans (O’Neil 2012). The apes and human are different from any other primate because they do not have tails. But the African apes and humans have essentially the same arrangement of internal organs, and share the same bones (O’Neil, 2012). They also have hands with thumbs that are sufficiently separate from the other fingers to allow them to be opposable for precision grips. The difference between humans and apes is our way of bipedalism. The body changed in locomotion because of evolution. Apes have developed heavier bodies weighing more than a normal primate. With thicker bodies and muscle tissue, Apes are covered in fur, which developed from being able to survive in a cold habitat (O’Neil, 2009). They can be found all over the world. An ape that normally walks on all four using their knuckles to support their weight, is the Chimpanzee (Debalfa, 2011). But they also do stand and walk upright using bipedal locomotion. Chimpanzees move efficiently in the trees by swinging from branch to branch. Their locomotion has been influenced by their varied environment, spending much of their time on the ground, but sleep in trees and often eat in them as well. Unlike apes, humans began developing elongated spines. The man’s arms are shorter and weaker compared to the legs. A human’s feet no longer had the grasping ability that once used to grasp and held objects (O’Neil, 2012). A big evolution change for a human’s locomotion was the modification of the human pelvis and spinal column to get a posture, providing a greater stability to walk and run. Which helped them survive over the years by using their speed to catch their food and potentially get away from…

    Archaic H. Sapiens

    Archaic H. sapiens possessed unique features compared with more modern H. sapiens. In contrast to modern H. sapiens, archaic H. sapiens had a longer, lower skull, a larger browridge, a bigger and more prominent face, a wider nasal aperture, a more projecting occipital bone, larger teeth, and very little, if any, chin. The postcranial bones of archaic H. sapiens were also thicker than modern people’s as well (Larsen, 2011).…

    Bipedalism Evolution

    Bipedalism Evolution

    However, that theory has been discredited with the discoveries of early hominid remains. For example, the 4.4 million year old female Ardipithecus ramidus, nicknamed “Ardi,” indicates an anatomical connection between early hominids and our closest living relative, the chimpanzee. Some of the physical similarities described in an article posted in Discover Magazine are, “the lower part of Ardi's hip was powerfully primitive, adapted for climbing. In contrast, the upper part of the hip, the ilium, was surprisingly broad -- a humanlike adaptation for walking on the ground.”(Niemark). However, based on Ardi’s remains, her brain size is estimated to be approximately 300-350 cubic centimeters. Fossil specimens such as Ardi, prove that bipedalism evolved before increased in brain size in early hominids.…

    Anthropolithic Chapter 10

    Chapter 1: Almost 70 million years ago, the most recent of apocalyptic extinction events occurred, wiping out the dinosaurs and signaling the start of a new era. The Cenozoic Era (age of mammals) has been split into seven sections called epochs with the final epoch being called the Holocene epoch, which brought forth a new ecosystem that harbored humanity. To conclude the eras that occurred previously, there have been five apocalyptic extinction events that occur roughly every 100 million year, and considering that humanity is 70 million years into the Cenozoic Era, humanity’s corrosion of Earth is considered to be the sixth Extinction event. Some scientists seek to distinguish the rise of man as a separate epoch known as the Anthropocene, or Epoch of Man, due to humanities obvious impact on the planet and ecosystems.…

    Hominin Species Essay

    This type of advancement is demonstrated numerous times throughout the history of early human evolution. One example of mosaic evolution is the changes to the pelvis over time to adapt towards bipedalism. Australopithecus afarensis is a prime example of pelvic changes while maintaining more ape-like qualities. A. afarensis had a shorter curved upper pelvis in comparison to apes. This curvature places the quadriceps closer to the front of the body, allowing easier leverage when pulling the femur forward in an upright posture. A. afarensis also had a wider pelvis, allowing for more stability while moving upright. A. afarensis did, however, keep its longer arms and curved fingers more suited for tree climbing. A. afarensis is a prime of mosaic evolution, the change in pelvis allowed for easy bipedal movement while the species as a whole more resembled that of an…

    Hominid Evolution Essay

    This species is more closely related to humans because their arms got thinner, legs got longer, and brains became larger. Researchers were able to figure this out after finding Turkana Boy; a complete skeleton of Homo erectus. Turkana Boy was very important because scientists were able to find out more specific characteristics of Homo erectus. Another major similarity to humans, is this is approximately the point where hominids became hairless. This was indicated because they began keeping cool by sweating. This was an advantage to persistence hunting because it would not give the animals with hair or fur a chance to slow down. Being hairless was definitely an advantage because they could catch more food faster and eat more calories; supporting their bigger brain. By looking at brain endocasts, scientists saw that because of the early hominids large brain, Homo erectus were able to talk. Also, hominids began cooking with fire. This allowed them to share and communicate which helped develop social relationships. During the time of the Homo sapiens, a fossil called the Hobbit indicated that the genus Homo may have not all evolved in Africa. The species may have left Africa without even realizing it because of a climate change that spread grasslands into Asia. Larger brains were an important process of coming closer to the evolution of human evolution. As time went on, the brains began larger and more similar to…

    What Does It Mean To Be Human

    In regards to anthropology, every human is human because they are affected by a culture that no other animals have in common with the human race. All humans have similar physical features such as bipedalism, but primates also share a lot of these aspects with humans. What really makes people human and separates them from primates is the cultural aspect of anthropology. Humanity is affected by culture, specifically, human culture. Museums, government, schools, the economy, etc., it’s all a part of human culture. It’s impossible to find a group of primates looking around at art, going to school, and electing political leaders. Apes can’t be found praying to an unknown deity above like some humans do.…
