활의 탄생 : 구석기시대는 끝났다! 시대를 바꾼 인류 역사상 최고의 무기 (도구의 탄생-9)

While the Earth warmly embraced all life forms, it also put them to the test with its capricious cycles of hot and cold. Naturally, those that could not survive vanished entirely. The Late Paleolithic Age was an ice age. Humankind endured the cold ice age by crafting spears, spear throwers, bone needles, and obsidian blades, and survived as predators by hunting and eating large animals. The Earth acted capriciously once again. The end of the ice age, the interglacial period, had arrived. The ice plains were covered by forests, and large animals disappeared. Newly thriving, small, and fast animals darted through dense thickets, fleeing from human spears. Now, there was no time for evolution. In the Early Paleolithic Age, if a species underwent a "species-wide restructuring" in the name of evolution and everyone died out, another human species would take their place. However, in the Late Paleolithic Age, only Homo sapiens remained. The lone remaining human had to choose innovation over evolution. At the end of the Paleolithic Age, what if the coming new era seeks to kill us all...? What were the first inventions and innovations humanity chose to face this new world?
