Bipedality is an adaptation that enables human beings to walk using two legs, therefore, differentiating humans from the other animals (Wu et al. 2). However, other animals do it sometimes like birds when on the ground, kangaroos, and apes. Humans are a perfect example of bipedalism because they use two legs always unlike other animals that do it partially. Certain body structures are necessary for bipedality. These body parts include; The pelvis of humans has blades that are not twisted and hold the internal organs when the humans are upright. Humans have more muscles in the pelvic region that ...

Introduction

Even though the concept of evolution is a typical narrative, it remains one of the most highly contentious of the topics. Major disagreements persist in the field, particularly when the evolutionary origin and physical modification of primates are the subject matter of discussion. Because of these differences, lots of significant finds in the field have attracted considerable amounts of opposition from experts depending on the species, or the side angle of evolution one recognizes (Ravosa and Dagosto). Disputes often center around locomotion and posture – whether a particular species was fully upright or could walk bipedally, brain size (intelligence), sexuality ...

Did Human Bipedalism Evolve from a Knuckle-walking Ape Ancestor Did Human Bipedalism Evolve from a Knuckle-walking Ape Ancestor

Introduction

The narratives of human evolution are one of the oft-told scientific stories whenever the topic of the origin of man crops up. However, this topic is also one of the thorniest and most highly contentious. There are major disagreements in the manner in which man first came to be, and every interpretation of almost every new find on the matter will be sure to find opposition among scholars on the field (Harcourt-Smith & Aiello, 2004). While there are numerous causes of disputes ...

Question 1

Cultural leveling describes how people from different cultures approach each other and try to reach common grounds regarding communication and interaction. This process is evident in Lee’s ethnographic fieldwork. Coming from white society, the researcher exhibited arrogance and considered himself superior, both intellectually and culturally, to the !Kung bushmen. He did this by extending to or cutting off the supply of tobacco from the Bushmen since he was the only source of the commodity in 1000 square miles (Lee). Besides, he neither shared his food with the Bushmen nor participated in their food-gathering activities. For this reason, the ...

Introduction

An ape is a primate whose appearance resembles that human being. Apes have no tails and most of them lived in Africa and Eastern Asia. Of the great apes, the only existing ones are chimpanzees, orangutans, bonobos and gorillas. On the other hand, hominids are primates who move/walk on two limbs. They are members of the great apes. However, this definition may not suggest that all hominids including the first ones walked on two limbs. (Juan, Ignacio and Mauricio, 2006). Many paleoanthropologists believe that hominids are the immediate ancestors of the modern human beings. In many cases, it is hard ...
