History Chapter 4: Early Humans and the Development of Civilization
Lifestyle and Survival of Early Human Societies
Early humans lived a lifestyle characterized by a constant search for essential resources, primarily food. They were hunter-gatherers who moved from one location to another rather than establishing permanent settlements. This nomadic existence was a necessity because they were fully dependent on the natural environment and resources like water. To meet their dietary and clothing needs, they relied on hunting animals. The skins of these animals provided material for garments, while their meat served as a primary food source.
Factors Influencing the Nomadic Lifestyle of Early Humans
There were four primary reasons why early humans did not stay in a single location for extended periods. First, resource depletion played a major role; humans had to travel to ensure they did not exhaust all local resources, specifically plant life and nearby water supplies. Once the immediate area could no longer provide for the group, they were forced to seek new territories. Second, the nature of water sources affected their movement. Because many rivers and lakes were seasonal and would dry up during certain times of the year, humans had to travel in search of reliable water.
Third, the availability of seasonal fruits influenced their migrations. People moved to various places in search of different plants that ripened in different seasons. Fourth, animal migration was a critical factor for early humans. Since their primary food source consisted of animals such as deer and wild cattle, hunters were required to follow the seasonal or geographical migrations of their prey to ensure a steady food supply.
Intelligence and Technological Adaptation in Prehistoric Survival
Early humans survived not just through physical strength but through their intelligence and ability to adapt. While they were physically strong enough to survive harsh climatic conditions without modern comforts or conventional food, they demonstrated smartness by creating their own tools to facilitate hunting and daily life. They did not have manufactured clothing, so they utilized their environment by wearing leaves or animal skins to protect themselves from the elements. Additionally, they learned how to construct shelters and collaborated by working together and sharing new skills. This combination of mental acuity and social cooperation was essential for their long-term survival.
Historical Records and the Evolution of Writing Systems
The period in human history before the invention of writing is understood primarily through archaeological evidence. One significant era discussed is the Sindhu Saraswati civilization, also known as the Indus Valley or Harrapara civilization. These people utilized a pictographic script referred to as Sindhu Lipi, which remains undeciphered to this day. Other ancient civilizations utilized distinct writing systems, such as the Cuneiform script used by the Sumerians in Mesopotamia and the Hieroglyphic script of Ancient Egypt. In Southern India and the Ganga valley, the Bhrami Script was used starting from approximately . This script was later standardized by Ashoka and the people of the southern parts during the .
Distinction Between Prehistory and Recorded History
Human history is divided into two major phases: Prehistory, which is the period before writing was invented, and History, which follows the invention of writing. Prehistory encompasses more than of human history, spanning from years ago to approximately years ago. Because there are no written records from this time, sources of information are limited to physical remains like tools, bones, pottery, and other artifacts. It is difficult to understand the specific thoughts or ideas of prehistoric people, and all dates and timelines are only approximate.
In contrast, recorded History accounts for less than of the total human timeline, beginning roughly years ago and continuing to the present day. Sources for this period include written records alongside physical artifacts. Literature from this era provides specific details regarding individual names, historical events, societal structures, and cultures. This allows for the recording of accurate dates, times, and events.
Biological and Cultural Revolutions in Human History
The history of humanity reflects both biological and cultural revolutions. The biological revolution refers to the physical change and evolution of species from the australopithecines to Homo sapiens. The cultural revolution involves the adaptation of skills, beliefs, and lifestyles over the last years. Humans survived by developing tools, techniques, and technologies to better utilize natural resources. A major turning point in this cultural progression was the shift from hunting and gathering to agriculture and food production, which is described as the emergence of civilizations.
Global Migration and Evolution of Early Human Species
Human ancestors first evolved in Africa, with major migrations beginning approximately years ago. Homo erectus, considered an early human ancestor, was the first hominin species to leave the African continent. Evidence of tools found in Asia and Europe suggests that the spread from Africa occurred between and years ago. Another major migration is noted to have occurred about years ago. Within the broader group of Hominin, which includes both Homo erectus and the species referred to as deepiens, Homo sapiens (modern humans) eventually evolved approximately years ago. The earliest human settlements were established in Asia, Europe, and Africa, regions collectively known as the Old World.
The Development and Significance of Stone Tools
The first stone tools were made by human ancestors around years ago. This development marked the beginning of a significant change in human behavior, distinguishing human ancestors from other animals. Tools served as extensions of the human body, enabling people to perform tasks that were impossible using their hands alone. Over time, these tools and the remains of some ancestors were buried under the earth's surface, where they are now found by archaeologists in the form of fossils. Specific species like Homo habilis, which lived in the Olduvai Gorge in Kenya and Lanzania, made the first chopper stone tools. While all Homo erectus were tool makers, it was Homo sapiens who developed more advanced technologies.
Chronological Ages of Human Technological Progress
Early human history is divided into several ages based on the materials and methods used for domestic life and tool production. The Paleolithic Age was characterized by hunting and gathering. The Mesolithic Age served as a transitional phase between the Paleolithic and Neolithic periods and was marked by the use of tiny stone tools. The Neolithic Age saw the introduction of agriculture and the domestication of animals. Subsequent periods are defined by the transition to metalworking: the Chalcolithic Age used both copper and stone, the Bronze Age utilized bronze for tool making, and the Iron Age was defined by the use of iron tools.
