Being Upright Importance

-The bonobo is the most recently discovered great ape in modern times.  It was revealed in 1929 by German anatomist Ernest Schwarz that a skull once thought belonging to a juvenile chimpanzee was in fact a new subspecies of chimpanzee known now as the Pan paniscus, or bonobo. (Waal 6)  During the Pleistocene epoch approximately 1.5 million years ago, the Congo River was formed in what is now the Democratic Republic of the Congo. (San Diego Zoo 2)  The river geographically segregated groups and individual chimpanzees south of the river resulting in these chimps being reproductively isolated.  Allopatric speciation took place as a response to new

Goodall, J. (1971). In the Shadow of Man. Boston: Houghton Mifflin. The author’s goal in writing this book is to discuss her experiences and what she had learned from studying wild Chimpanzees. Goodall wrote this book in order to convey her knowledge of a species of animal she loves very much, so that others may become educated and join her in protecting them. She dreamed of going to Africa to see them, and was offered a job by Dr. Lewis Leakey. Goodall wanted nothing more than a chance to help. Her experiences in surrounding herself with them have completely changed the way scientists conduct field research. Whether she intended to or not, the data she has collected has debunked myths and uncovered truths about chimpanzees, while bringing more light to human behavior.

Throughout the term, reading the book, “Through a Window” by Jane Goodall has been quite intriguing for me, in that it has inspired me with new ideas and perceptions about how our own species has evolved over time. I have really enjoyed seeing the many similarities that hominids share with other primate species, especially chimpanzees. Goodall’s research only further proves that we are not only extremely biologically similar to chimpanzees in our DNA, but have many behavioral similarities as well. The film, “Monkey in the Mirror” also shows support for our likeness in intellectuality. These documented findings on chimpanzee and human resemblances provides the strong evidence needed to conclude the fact that humans do indeed share a common ancestor with great apes.

This book was about the life of apes in their natural habitat that is being destroyed. Stanford highly pushed the idea of extinction and what people are doing to the apes. Stanford explains the threats to the ape's survival and tells us ideas that could help stop or slow down the decline of the ape population. He tells us about the complex cultural, social, economic and

We share almost 99 percent of our genetic material with chimpanzees. Yet we have several traits that are very different. Two legged walking, or bipedalism seems to be one of the earliest of the major hominine characteristics to have evolved. To

I have to assume that the skulls that were closest to walking on four legs lived in environments with a lot of trees and high grounds. That being said, now I have to assume that our ancestors eventually found it easier to live in long plains and migrated which made them lose the need to be efficient on all fours, thus leading to bipedalism.

While I thought that Peterson’s descriptions sufficed to help the readers see how apes were treated – dead or alive, the pictures were more shocking. Originally, I skipped over the pictures, but they served to help bring Peterson’s words to life. Prior

The Australopithecine are some of the earliest known hominids and they embody many characteristics that are associated with bipedalism. Bipedalism is a highly specialized and unusual form of primate locomotion that sets modern humans apart from all other living primates as we are the only extant obligate bipeds. Many evolutionary biologists and paleoanthropologists have devoted innumerable research hours to attempting to understand this unique form of locomotion and how it evolved. A number of interdependent morphological adaptations occurred over a long period of time to solve challenges posed by habitual bipedalism. As a result, there are obvious differences that exist between early and late hominin species.

They found that Au. ramidus had very similar characteristics to Sahelanthropus Tchadensis an ancestor that dates to 6-7 million years ago. Ardi had a foot that was primitive and had an opposable big toe which was most likely used to grab on branches. She also had a long and curvy spine just like humans. Its pelvis was large like those of apes and had short and broad shoulders suggesting it had a lower center of mass and could possibly walk on one leg at a time. But it is also thought that it was still spending a lot of time in the trees as well. Thus, why it is thought to be intermediate form of bipedalism it lived in both worlds, walking upright, and climbing trees, equal success in both biospheres. Although Ardi is not the connection to apes it still served to prove that the ancestor of apes was a lot more primitive than we believed. There are still several questions to be answered in this puzzle called our ancestry. It may seem that more questions arise as more clues are found, but that is science, there would be no intrigue left if all questions were

Primates first evolved from the trees of tropical forests, later to the ground. Through the times of promisians to human, many characteristics has been represented due to the adaptations to new environments and resulted in evolutionary changes. The Earth has encountered several geological and climatic changes over time. For the primates existed at that time had to adjust itself especially in body configurations and locomotion in order to better survive. It is important to be aware of this information since we are the part of occurring changes as well. Throughout the evolution owing to

First, evidence from the hominid fossil Ardy and archaeological evidence from the same area where Ardy was found points to the evolution of bipedalism in a woodland environment. This goes against the previous assumption that bipeds adapted to a more desolate environment. Additionally, it was also previously believed that bipedalism started with organisms that walked on two legs and their knuckles as a today’s chimp walk. However, there is no evidence in Ardy’s bones that it ever walked using its knuckles. On the other hand, Ardy possesses a short, broad hipbone which allows for bipedalism, but also a much longer lower half of the pelvis which would be more useful for climbing. Consequently, while Ardy could walk on two legs, it could not walk as well as future bipeds such as the fossil Lucy or modern humans. Lucy is often described as “the ape who stood up” and is further down the evolutionary track toward modern humans. This evolutionary adaptation to stand and walk on two legs opened great doors for humankind. Most important was the fact that walking on two limbs rather than four freed up our very special hands and empowered humankind to build tools and reshape the world as no creature could

Approximately 4 million years ago a wonderful evolutionary phenomenon was happening in Africa. Early hominids, man’s ancestors, were beginning a giant leap in their evolution. These hominids were moving out of the forest and beginning to walk upright, out on the open plains (Fagan, 98). This change from quadrupedalism was the most significant adaptation that ever happened to these early hominids. It caused many adaptations that make man what he is today. This process occurred in early hominids for many different reasons, each reason helping to perfect the upright walking posture. Bipedalism is thought to have occurred because of changes in environment, feeding habits, thermal regulation, and

There has been much debate concerning the origins of bipedalism. Bipedalism, or the ability to move on two legs (eLucy, 2007) was said to have emerged due to climate change in East Africa, for sexual display purpose, to reduce exposure to sunlight, the need to use weapons and tools and many more (NOVA, 2013). There are numerous arguments associated with bipedalism as no one can be entirely sure as to what constituted to the emergence of this trait, which was first present in hominins Australopithecus Afarensis. Anthropologists claim that there is a missing link in the evolutionary lineage that makes it hard to confirm the real cause of bipedalism emergence. However, there are some models which are widely accepted by scientific world, such

There are many traits and behaviors which can be used to define as early humans, such as big brains, language, and distinctive cultural or behavioral traits such as tool technology. One of the most fundamental human characteristic which distinguish early hominins from other apes is bipedalism. (Kottak) Walking upright on two legs is the trait that defines the hominin lineage. It took paleoanthropologists a long time to realize that bipedalism is the key difference between human and ape. They tended to believe large brains made hominins unique and it was a reasonable conclusion at that time because the only available hominin fossils were Neanderthals and Homo Erectus. However, with more and more earlier hominin fossils being found, paleoanthropologists
