Before the existence of an advanced civilization many steps of evolution is required. The complex human society is one of the best examples there is. For example the revolutionary steps from the Paleolithic and the Neolithic to the Modern World is filled with wonder and awe. However, the ascents involved is not that extraordinary; if it is being closely observed.

Foremost, the Nomadic People of the Paleolithic Age depends heavily on the moving herds of animals for food and sometimes even clothing. Therefore, nomads of Paleolithic Age follow their preys and move with them as the various animals migrates as the season changes through out the year. Even though the nomads’ food source was usually abundant and finding of shelters were not much of a problem, but the ongoing journeys with the hunted animals provides little security against several other different big game predators, that preys upon both men and the animals nomads travel with.

The harsh environment nomads face gradually forced them to discover a much easier lifestyle. And that began the age of Neolithic or the New Stone Age. During the New Stone age people started to settle down and build their own shelters instead of dwelling in caves. Also the once nomads learned how to grow their own food. As a result population grew as life became easier and more bearable.

The result of the population growth directly affected the early people in many ways. One of them is that due to scarce food during the nomadic period, clans had to dispatch extra members when it reach to a certain number. However, with the much more settled society be rid of extra members is no longer necessary. Therefore, more manual labors were available when needed.

As the early people learned how to adapt and modify to the environment that they lived in, more advanced settlements began to emerge. Than gradually advance settlements turned into towns, cities, and diverse independent nations. Although the revolutionary steps took well over centuries, but the result of the time consuming evolution is the modern civilization that continues the nurturing of many more genius scientific minds that will bring the modern society into being much more advanced civilization.
