How did weather affect the end of the old stone age?

Weather during the end of the old stone age, or Upper Paleolithic period, played a role in the development of new technologies and adaptations by early humans. For example, changing weather patterns may have led to shifts in animal migration, influencing hunting strategies and tool-making techniques. Severe weather events, such as harsh winters or droughts, could have also impacted food availability and led to changes in human behavior and social structures.
