Ardipithecus

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).…

Reading Response to White et al.: Ardipithecus ramidus and the Paleobiology of Early Hominids. In the article, Ardipithecus ramidus and the Paleobiology of Early Hominids, by Tim D. White et al. , the Ardipithecus ramidus specimen ARA-VP-6/500 from the Aramis vertebrate paleontology locality 1 (ARA-VP-1) expedition is examined in depth. The ARA-VP-1 is located in the Middle Awash and expands into the Central Awash Complex (CAC) with different localities, numbered from 1 up. The Middle Awash…

The great Ardipithecus radius (Ardi) was alive on earth around 4.4 million years go. Ardi lived in Eastern Africa where they lived in Eastern Africa and lived in the forest. Also Ardi were known as strict “omnivores”. Lastly, the brain of Ardi’s was about 300 to 1500 cubic centimeters and walked up right like humans (bipedal). Autralopithecus Afarensis (Lucy) was alive on earth around 3.2 million years ago. Lucy lived in Africa where they lived in wet and dry environment typically wooden areas…

insight of our ancestors. Ardipithecus fossils were a crucial find to the field of archeology, which created new suggestions concerning features that associated them with modern Homo sapiens and primitive apes. The structure of the Ardipithecus has provided information which separates…

Introduction        As time has passed by, the size of the cranium changed. With that being said, the size of the cranium changed in result of better nutrition. On another note, the width of the pelvis changed as well. In that case, the width of the pelvis changed in result of its bipedality. Therefore, bipedality determines whether or not a genus homo can walk, run, as well as their ability to create tools in order to survive. Ardipithecus ramidus…

The position of the foramen magnum, the length of the leg, the shape of the spine and pelvis are four of the seven steps of bipedality. The position of the foramen magnum is located in the bottom of the skull, near the teeth in humans, and in the rear area for apes. This distinguish humans and apes because it demonstrates that the human head sits on the body rather than on the front of the body, like apes. The shape of the spine is s-shaped for humans and c-shaped for apes. Specifically, in…

Bipedalism and Environmental Adaptability Bipedalism as general definition, is the ability of all types of animals standing in two feet. The environmental Adaptability is the way to get used to a habitat and weather. Both of them played an important role in the evolution of modern humans. According to the book “Worlds Together, Worlds Apart” by Robert Tignor, describes the advantages of bipedalism and the environmental adaptations that allowed modern humans to live into two different…

Majungasaurus was an average sized (compared to it’s close relatives) theropod dinosaur that lived in Madagascar from 70 to 66 million years ago, at the end of the Cretaceous Period. Like other abelisaurids (members of the family Abelisauridae) , the Majungasaurus was a two-footed predator with a short snout. Although the forelimbs are not completely known as of yet, they were very short, while the hind limbs were longer and quite stocky. It can be distinguished from other dinosaurs in it’s…

There are many theories regarding bipedalism in early great apes or hominids, as well as some advantage provided by bipedalism have raised and been heavily debated. These theories are a attempt to remake of the past in which bipeds lived, to make a idea on how bipedalism emerged as a necessity for daily activity. As data gets bigger and the history of bipedalism goes further back into history,anthropologist still need to find a theory that encloses all ideas. There are two anthropologist who…

Firstly, bipeds move by using two rear limbs whilst quadrupeds move by using four rear limbs. Both bipeds and quadrupeds use distinct gaits for locomotion. A gait is defined as a particular style of movement. Animals’ characteristic legs and gaits are due to natural selection and experiential learning. [1] Several different properties are used to classify gaits, these are outlined below. A stride is one complete cycle of leg movements. Stride frequency is the number of strides taken in a…
