Essays on Grasslands

Like many other United States National Parks, Badlands is unique unto itself with physical attributes that when they are seen one knows it is Badlands National Park. Located in an area rich with history, the Badlands was created and founded as a national monument in 1939 by President Roosevelt before officially becoming a national park in 1978 (Steiner, 1993). The landscape of buttes, ravines, and hills found in the midst of the prairie of Southwestern South Dakota influenced the Lakota Sioux to call the area, ‘mako sica’ or ‘badlands’ (“South Dakota Legends,” 2003). The Sioux Pine Ridge reservation lies ...

Introduction

One of the largest areas of the world where pastoral nomadism and irrigating agriculture had been predominant throughout the history is Central Asia. There existed a set of aspects of geography and ecology of Central Asia that influenced the emergence of pastoral nomadism and irrigation agriculture in that territory. In this paper we will attempt to explore some of the causes and effects of pastoral nomadism and irrigating agriculture in Central Asia, taking into consideration its ecological and historic settings.

Ecological reasons

First of all, let’s speak about some of ecological reasons of the appearance of pastoral nomadism and irrigating ...

On the one hand some of the animals look exactly into the camera lens and it seems as if they know how to pose for nice photos. On the other hand some of the animals do not look into the camera at all or even show their backs. It gives the impression that animals do not like additional attention and to be in the zoo at all. As if they are too tired of their everyday activities. To my mind some of the photos show that some of the animals have to little place for them in the zoo. ...

The fossil record of hominids provides evidence for evolutionary processes that ultimately defined and shaped humanity. The record documents the emergence of bipedalism, the origin of the genus Homo, the initial utilization of tools made of stone, the gradual increase in brain size, the appearance of the present-day humans or Homo sapiens, and the development of advanced tools and cultural values. According to the National Research Council (2010), the evolutionary events described in geological records coincided with significant changes in Eurasian and African climate. Hence, they raise the possibility that past environmental features controlled or affected major junctures in ...

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 ...

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 ...
