The evolution of humans on Earth is a complex process that can be divided into several stages. Here are the main ones:

1. Evolution from Primates: The first step in human evolution began with the divergence from our last common ancestor with the primates, specifically the chimpanzees and bonobos, around 5-7 million years ago. This period saw the emergence of the first hominins, or early humans, such as Sahelanthropus tchadensis and Ardipithecus ramidus.

2. Australopithecus: Around 4 million years ago, the Australopithecus appeared. They were the first hominins to show significant bipedalism, meaning they could walk on two legs. The most famous Australopithecus is "Lucy," a 3.2 million-year-old skeleton discovered in 1974.

3. Homo Habilis: Around 2.5 million years ago, Homo habilis emerged. They are believed to be the first species of the Homo genus and were the first to use stone tools, marking the beginning of the Stone Age.

4. Homo Erectus: Homo erectus appeared around 1.9 million years ago. They were the first hominins to leave Africa and spread across parts of Asia and Europe. They also used more complex tools and were likely the first to use fire.

5. Homo Neanderthalensis: Neanderthals are our closest extinct human relative. They lived in Europe and parts of Asia from about 400,000 to 40,000 years ago. They had a more advanced culture than their predecessors, with evidence of burial rituals and body decoration.

6. Homo Sapiens: Modern humans, Homo sapiens, appeared around 300,000 years ago in Africa, and are the only species of human to survive to the present day. Homo sapiens have shown unprecedented levels of cultural, technological, and societal development, leading to the world as we know it today.

It's important to note that this is a simplified version of human evolution. The full process is much more complex and involves many more species and transitional forms.
