For a long time, Australopithecus afarensis was considered as the earliest known bipedal hominid. This made this species, which was dated to have existed around 3.5 million years ago, the oldest member of the human clan. However, the discovery of the species, Australopithecus anamensis pushed the age of the bipedal hominids further back by around 600000 years (Tomasik, 2002).

History of the Discovery of Australopithecus anamensis

In 1965, the first fossilized specimen of A. anamensis was discovered by a research team from the Harvard University in the Kanapoi region that lies on the west of Lake Turkana in Kenya. Although at that time the fossil, which was a humerus ...

For centuries, scientists have been trying to map the concept of fear. This emotion is eminent from birth until death. Sociologists believe that this fear is what molds the society and the individual. It is the fear of the unknown that has forced us to develop medicine. Fear, like every other emotion, is developed due to thought. If thoughts did not exist, then the feeling of fear would not have existed either. Once we understand what fear is derived from, we comprehend that it is our own imagination, and ...

Invertebrates are animal genus that lack or do not build up a spinal column. They account for the largest percent of all the living species. The first animals to have evolved were invertebrates. Data from fossils collection shows that invertebrates were there 600 million years ago. Some paleontologists propose that invertebrate animals emerged much earlier probably one billion years ago. Trace fossils such as burrows and tracks established in the Tonian age signify the presence of triploblastic worms approximately as large and complex as earthworms. Animals began diversifying at around 453 MYA, and many of the essential groups of invertebrates ...

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 ...
