Kivilajejen

Kivilajejen, also known as the "stone age," is a prehistoric period characterized by the use of stone tools by early human populations. This era spans from the time humans first began to use stone tools, estimated to be around 2.6 million years ago, to the end of the Paleolithic period, which varies by region but generally ends around 10,000 years ago with the advent of the Neolithic period. The term "kivilajejen" is derived from the Finnish word "kivi," meaning stone, and "lajejen," meaning age.

During the kivilajejen, humans developed various types of stone tools, including hand axes, scrapers, and flakes. These tools were primarily used for hunting, gathering, and processing food. The development of stone tools marked a significant milestone in human evolution, as it allowed for the creation of more efficient and effective tools than those made from natural materials alone.

The kivilajejen is further divided into several sub-periods, including the Lower Paleolithic, Middle Paleolithic, and Upper Paleolithic. Each of these periods is characterized by distinct types of stone tools and technological advancements. For example, the Lower Paleolithic is known for its simple, crude tools, while the Upper Paleolithic saw the development of more sophisticated tools and the emergence of symbolic behavior.

The kivilajejen is an important period in human history, as it provides insights into the development of human culture, technology, and social structures. Archaeological evidence from this period, such as stone tools and artifacts, helps researchers understand the lives of early human populations and their interactions with the environment.
