The spear

According to traces found in South Africa, our ancestors already used spears with carved stone tips 500,000 years ago. A crucial leap in evolution that allowed them to better protect themselves from predators and to spend fewer nights fasting. The spear may be our oldest tool: it exists wherever we go, either as a rudimentary stick of sharpened wood in ancient times or a combat projectile for centuries, passing through these recently created harmless Mini earrings with two pieces of plexiglas, proving that technology almost always depends on the use that one gives it. And you, what will you do with them?
