Early humans evolved tools to make their lives easier. The first tools, used by Homo habilis around 2 million years ago, were found stones. Later humans developed more advanced tools like hand axes and blades. Tools helped early humans hunt, process food, and protect themselves, driving the evolution to more intelligent species like Homo erectus, Neanderthals, and Cro-Magnon. The development of tools such as farming equipment allowed modern humans to survive and spread throughout the world.
