1. Since humans and other primates share a variety of characteristics‚ other primates provide important observations about early humans. Homologies between hominids and other primates enhance to behavior because the physiological and cognitive formations that manage to control human demeanor are likely related to those of other primates than to members of other taxonomic groups. The reality of this broad collection of homologous traits‚ the commodity of the average evolutionary history of the primates

Did a Fall From a Tree Kill Lucy‚ Our Famous Ancestor? Adam Hoffman opens his discussion by describing our first human ancestor‚ Lucy‚ who is believed to be alive 3.18 million years ago. According to research‚ some fractional injuries could point to her falling to her death. Hoffman includes a statement from John Kappelman which states that this is the first autopsy of her cause of death to date. Donald Johanson discovered Lucy in 1974‚ and claims that Lucy’s bone breakage matches that of other

Introduction to Hominid Evolution Hominid evolution is the theory of the origins of the human species (Homo sapiens). Current understanding of human origins is obtained largely from the findings of paleontology‚ anthropology‚ and genetics. Of all primates‚ humans share particularly close affinity to other members of a group known as hominoids‚ or apes. Humans and their immediate ancestors‚ known as hominids‚ are notable among hominoids for their bipedal locomotion (Using two legs for walking)

Early human evolution is characterised by speciation. The term speciation refers to “the formation of new and distinct species in the course of evolution”. Recently‚ experts in the field of evolution have given special emphasis to the new and most controversial issue of Homo floresiensis. Homo floresiensis (known as the Hobbit Man and LB1) is the little bodied and an extinct species that was discovered from a fossil and simple stone tools in 2003 on the island of Flores in Indonesia. Scientists indicate

ANDREW KRAUSS “HUMAN REVOLUTION” 1. When anthropologists discovered “Lucy” in 1974‚ they considered her the oldest hominid of age 3.6 million years ago. How has the discovery of old hominid-like remains affected the “line” of evolutionary descent? They have declared sahelanthropus to be on the line this led to gorillas‚ not humans. Explain why a newer model of human ancestry is emerging. Different species are reproducing together. 2. What problem do paleontologists have with cataloguing

A very good morning to my teachers and my fellow students.I am here today to give a speech about our role to ‘save our environment’. Today‚ when environment is being polluted so vigorously‚ everyone has only one question on their mind that is how to save environment from being polluted. The strongest way to protect environment is save trees. Trees play an important role to keep air clean. If there will be no fresh air available then how will human beings‚ animal‚ and birds survive? Therefore

Machines This is an age of machine. Machine has acquired a high priority in the modern era. It has come to occupy a place of major importance in the life of man. In all spheres and walks of life machine comes to the aid of man. Right from the time of waking up in the morning till going to bed at night‚ man continues to make use of some machine or the other. For example‚ man wakes up with the help of a machine (alarm watch)‚ takes bath with the help of water brought by and heated by machine‚ enjoys

The models on the disbursement of modern humans include the Out of Africa hypothesis and the Multiregional Continuity hypothesis. The Out of Africa hypothesis explains that modern humans first evolved in Africa and then migrated out to Asia and Europe‚ displacing the archaic Homo sapiens already habituated there. In contrast‚ the Multiregional Continuity hypothesis explains that evolution of modern humans occurred regionally and without replacement‚ meaning that each continent’s archaic H. sapiens

The purpose of this essay is to show the similarity and differences between humans and Chimpanzees. They are our closest living relatives‚ when we didn’t even know about them until Charles Darwin wrote about and popularized Chimpanzees in 1859. Chimpanzees’ discoveries have been studied recently. Chimpanzees are often miscalled monkeys. Those who are considered in the great ape family are the following: humans‚ chimpanzees‚ orangutans‚ and gorillas. Homo sapiens are the only species of human kind

The Olmec culture has associated their art with the jaguar. To them‚ the jaguar is a powerful and mysterious animal that they would worship. Infantile sculptures that were created by the Olmec were found in Mesoamerica. The sculptures are those of naked infants where the sex is usually not denoted. Some of the sculptures can be found with feline characteristics such as that of a jaguar’s mouth. There is speculation that the mouths of the figures appear to be of jaguars due to the similarity between
