Bipedalism

Ocean Acidification refers to when the pH of the ocean is reduced over a long period of time, which is primarily due to the extensive amounts of Carbon Dioxide in the air which reacts with the water in the sea. This problem is affecting the world’s oceans, and severely impacts those that rely on the sea animals in the ocean. Relation to the Digestive System: Oceans are not naturally acidic, but are slightly basic due to them having a pH of 8.06. Through excessive human pollution, such as…

curvature forms a sort of C-shape as opposed to the Homo sapiens’ S-shape. This curve is perfect for a quadruped, but on two legs it would not be able to properly distribute weight evenly, resulting in increased impact. Essentially, this means that bipedalism is possible for extremely…

evolution first began in Africa roughly 6 million years ago and it describes the very long process that our ancestors went through to become modern day humans. One of the first original human traits that were discovered around 4 million years ago was bipedalism, which is the ability to walk on two legs. Over a long period of times humans have grown taller and have developed more complex language skills. Natural selection is a theory based off of Charles Darwin. This theory states that organisms…

1. A.) A physical trait that helps differentiate Homo ergaster from early hominins is that they were bipedal. They did not have a flared ilium or long arms. Homo ergaster individuals had short arms and long legs like the modern human. Another physical trait that is extremely similar to that of humankind is the pelvis structure for childbirth. In order for the complication of childbearing to be reduced the question of having a small brain or a change in the pelvic structured would be what…

The origins of human life are riddled with mystery, complexity, and controversy. Archeologists and historians have been able to unearth clues from beginnings of Human civilization in spite of various contentions. Evolution has transformed virtually every organism to grace planet Earth, and the evolutionary process that led to the modern day human commenced in the continent of Africa. Furthermore, as humanity developed the sexual dimorphism between both sexes led to varying roles for males and…

Ardi’s fossils were found alongside faunal remains which indicates Ardi lived in a wooded environment which then contradicts the open savanna theory for the origin of bipedalism. That also states humans learned to walk upright as climates became drier and their environments became more open and grassy (Human Family Tree | The Smithsonian Institution's Human Origins Program. (2010, March 01). Retrieved January 15, 2017,…

Chimpanzees and bonobos are characterized as the closest living relatives of humans. Studies have shown that the humans and apes descended from the same ancestor nearly six million years ago. It was at this time that their DNA sequences began to diverge from one another. Chimpanzees (Pan troglodytes) and bonobos (Pan paniscus) stemmed from the same Pan ancestor, but split about two million years ago when the Congo River formed (Prufer, 2012). While the separation between the Homo and Pan…

talk about ‘primitive’ and ‘advanced’ extant primates is less or more like humans and that is an incorrect usage. Humans do indeed have some advanced features (features not found in their ancestors) such as large brains and feet adapted to habitual bipedalism, but then all extant species tend to have a few specialised features that set them apart from other species (specialised throat anatomy to allow extremely loud vocalisations in Indri, multi-chambered stomachs for leaf fermentation in…

Africa itself, the climate change causes increasing temperature, where it causes drought, and lack of water which causes trees, plants, and vegetation to die. While migrating, Homo Sapiens sure have huge benefit because of their locomotion, which is bipedalism, enabling them to look further since they are higher, allowing them to scan in distance for danger. Other than that, they created tools which allow them to survive, such as mousterian. Other than that, Homo Sapiens also has a unique bone…

Ch.1 Clive Gamble’s “Settling the Earth: The Archaeology of Deep Human History,” begins with a brief discussion of a shared common ancestor amongst Africans believing this process of expansion settled the world. In addition, he provides a summary of hominins, a group we are included in with our extinct ancestors, Australopithecines, and Neanderthals (Gamble 2013: 23). As the text progressed, I began to understand the author’s notion of this first chapter. I believe this evolution of human…
