Essays on Homo Erectus

The gradual change in human structure, genetic composition, and anatomy over a period of time is called human evolution. The process of evolution dates back to six million years ago when the ancestors of modern human beings underwent simultaneous and gradual body changes. These changes were passed from one generation to another coupled with modifications. Modifications in genetic structure come by as a result of adaptations. Organisms usually undergo adaptations to help them reproduce or survive certain conditions in their habitat. Individuals inherit the most desirable characteristics from their ancestors that enable them survive and reproduce successfully. Those who ...

Abrigo do Lagar Velho is a rock-shelter in the Portuguese valley that is famous for the stratigraphic range of the Upper Paleolithic human occupations within that area.

Absolute dating technique (chronometric dating) refers to the process of revealing the age on a certain time scale.

Acclimatization is the response of an organism to a gradual change in environmental conditions by adjusting and sustaining within these changes. Acheulian (Acheulean) is a tool made of stone that had round cutting edges and was used during the Lower Palaeolithic era.

Adolescent growth spurt refers to the sharp growth in height and weight rates t during adolescence.

Aegyptopithecus refers to the extinct primate of the Oligocene Period, resembling a modern-day lemur, whose fossils were found in Egypt. Afar Triangle is the region that is part of the ...

Describe which general fossil primate groups appear and radiate during the following geological epochs: Eocene, Miocene, Pliocene, Pleistocene. For each of the geological epochs, identify the general primate group that first appears and radiates during that epoch. In addition, give the time range in millions of years for each epoch and provide at least one example of a specific primate genus and/ or species that is representative of each general primate group. 2. List and briefly describe at least five elements of the post-cranial anatomy found in humans, but not in apes, that facilitate efficient bipedal locomotion. Provide specific ...

Human beings all belong to the species Homo sapiens. However, both Neanderthals and modern humans are most likely the homo heidelbergensis descendants. Homo sapiens are believed to have evolved in Africa nearly 200,000 years ago and gradually migrated north, through the Middle East, to Europe and Asia. A skull 160,000 years old was discovered at the Herto site area of Ethiopia (Anthro.palomar.edu, 2010). Other more advanced transitional forms have been discovered at Laetoli in Tanzania and are 120,000 years old. About 115,000 years ago, some early modern humans (Homo sapiens) ago widened their range to ...

What was Homo erectus like? What were they like physically, and what do we know of their behaviors, tools, etc.?

Answer. Homo erectus was around 1.5 million-year-old ancestor of humans and was named so because they were considered to remain upright without any bending. The height of Homo erectus ranged from 3 feet to 6 feet in height and they had relatively longer legs and shorter hands he . The species was known for exceptionally big brain sizes and was supposed to originate from Africa. They were primarily hunters who were always in search of food to quench their large appetites. Homo erectus was proficient in the use of almost all of the stone tools and is known to use ...

What was Homo erectus like? What were they like physically, and what do we know of their behaviors, tools, etc.?

Homo erectus, also referred to as the “upright man” was the earliest known early human to possess the characteristics of the modern man. Unlike its predecessors, Homo erectus was bipedal, that is, they were the first humans in the evolution line to walk in two legs with an upright posture (Science & Technology). They had the biggest brains, in proportion to their body sizes, as compared to their predecessors. They also had longer legs and sorter arms. This was because they had reduced their adaptation towards tree climbing. They also had a larger variation in heights as compared to other ...

What was Homo erectus like? What were they like physically, and what do we know of their behaviors, tools, etc.?

The Homo erectus had a long low skull, thick brow ridges, a small brain, and a big jaw. Their legs and arms were short, and they were 5 ft. 3 inches tall. They had narrower hips, which increased their speed. They were hunters and toolmakers. They had simple tools such as the hand axe, which was used for hunting. 2. When did the species Homo erectus first appear on earth, according to our current information?

The Homo erectus first appeared on earth 1,300,000 years ago in East African Rift Valley.

3. How did Homo erectus hunt? How was the relative absence of body hair important to their survival? The Homo erectus hunted during the ...

` 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 ...

The appearance of modern humans has changed greatly over the 2 million years or so after evolving from the Australopithecines and the appearance of Homo habilis who was the first human ancestor to fall under the homo genus and lived about 2.4 million years ago. Homo Erectus followed living between 1.3 to 1.8 million years ago. Homo erectus fossils have been found in Africa, China, India and Java. here was a cranium found in Bodo, Africa in 1976, the Peking man found in China. Although they lived in varying environments the Homo Erectus had a number of universal traits. ...
