Essays on Journal Of Human Evolution

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 ...

` The evolution of human beings is closely related to the evolution of the human brain. Brain capacity demonstrates how humans evolved from primitive to modern forms. By examining brain capacity across three different species of primates, namely Australopithecuas Africanus, Homo Habilis and Homo Erectus, it is possible to notice how brain capacity drastically increased, and with it, other modifications also took place, thus allowing modern humans (Homo Sapiens) to evolve into the present form. Based on primary research, this paper will examine brain capacity as a fundamental evolution characteristic, and will trace the transformations which took place from one ...

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 ...
