Anthropologists discovered a 2.5 million year old fossil of a homo hominid, the first human-like ancestors to walk upright. They called the fossil "Lucy".
Homo Hominids pioneered the Paleolithic Age. They had opposable thumbs to carry food and children, and tools to cut meat and bone.
1.6 million years ago, they developed into Homo Erectus. Homo Erectus used their knowledge to invent fire, tools for easier survival, and early forms of language.
Around 1 million years ago, Homo Sapiens, or modern humans developed.They competed with Neanderthals, a similar species but not an ancestor, for land until the superior hunting strategies of Homo Sapiens helped them emerge victorious.
Humans of the Paleolithic age were nomads and hunter-gatherers.For easier survival, they made a lot of tools. They also started to create art. A new discovery would shape human evolution even further.
The discovery of agriculture around the world led to the Neolithic Revolution. It provided an steady, alternative source of food for rising populations. Domestication of animals helped with livestock.
