The Mesolithic era is generally considered a transitional phase between the Paleolithic and Neolithic periods, starting around 10,000 years ago. During this time, humans continued to rely on primitive fishing, hunting, and gathering lifestyles, but began to see some new developments: the production of microliths, the use of composite tools, the domestication of dogs, the invention of the bow and arrow and throwing spears, advancements in fishing techniques, and more efficient utilization of natural resources. These changes reflect an enhanced ability of humans to adapt to their environment, yet there remains debate within academia regarding the universality of the Mesolithic era.
The Mesolithic period has been discovered across Eurasia, including the Maglemosian culture and the Azilian culture in Europe, as well as the Hohokam culture in Asia. However, scholars have differing opinions on this matter. Some believe the Mesolithic era existed only in specific regions, while others argue that it represents a universally present transitional phase. Additionally, some scholars contend that the concept is too broad, hindering the definition of specific cultures.
Currently, resolving this issue requires more archaeological evidence and in-depth research.
