Human evolution is the 7-million-year journey showing how ape-like ancestors became modern humans (Homo sapiens). The first key change was bipedalism—walking on two feet—which started around 3.6 million years ago, freeing up our ancestors' hands!
Have you ever looked at your hands or wondered why you can stand up so tall? You are part of an incredible, super-long story called human evolution!
This amazing journey shows how people like us, called Homo sapiens, changed over millions of years from older, ape-like ancestors! Think of it like a family tree that goes back further than any grandparent. Scientists believe human evolution started in Africa about 6 to 7 million years ago with the first creatures called hominins. This whole process is how we went from walking on four legs to walking tall on just two! It took a loooong time, but every step changed who we are today.
Mira says:
"It's mind-blowing that we share ancestors with apes! Imagine those early hominins looking up from the tall grass because they could finally stand on two legs. That one change totally reshaped everything!"
What is Bipedalism? The Big First Step!
The very first big change that scientists look for to see an early human ancestor is called bipedalism. That's just a fancy word for walking on two feet!
While some early ancestors might have walked upright sometimes, scientists think that about 3.6 million years ago, walking on two legs became a regular, energy-saving way to travel. Why was this so important for kids to learn about? Because when our ancestors stood up, their hands were suddenly free!
Mind-Blowing Fact!
The earliest known species that showed signs of walking upright, like *Sahelanthropus tchadensis*, lived around 7 million years ago!
Meet the Famous Family: Australopithecus
After the very first upright walkers, we meet a famous group called the Australopithecines, which means 'Southern Ape.' They lived in Africa starting around 4 million years ago.
The most famous member of this family is a female skeleton nicknamed 'Lucy', who lived about 3 million years ago! Lucy was only about 3.5 feet tall, with a brain much smaller than ours, but she could definitely walk on two feet, even if she was still great at climbing trees!
Australopithecus started appearing.
Genus *Homo* began to appear.
First modern humans (*Homo sapiens*) evolved.
How Did the Genus Homo Get So Smart?
Around 2.5 million years ago, a new group of early humans appeared, and scientists gave them the special genus name *Homo*, which means 'man' or 'human' in Latin!
These new *Homo* species had something very important: bigger brains than the Australopithecines!
The Handy Man: Homo habilis
The first *Homo* species we often talk about is *Homo habilis*, which means 'handy man.' They were the first to regularly create and use simple stone tools!
The Upright Man: Homo erectus
Next came *Homo erectus*, the 'upright man.' They were better at standing tall, which let them travel far! *Homo erectus* was the first human ancestor to travel outside of Africa and explore other continents!
💡 Did You Know?
One of the biggest breakthroughs for *Homo erectus* was learning to control FIRE! Fire kept them warm, scared away big animals, and let them cook food, which gave them extra energy to grow even bigger brains!

What is the name for walking on two feet, which was the first big step in human evolution?
Why Are We Called Homo sapiens?
Finally, about 200,000 years ago, the first *Homo sapiens* evolved! Our scientific name, *Homo sapiens*, means 'wise man' or 'thinking man.'
We have the biggest brains of all the human species, which allowed us to develop amazing things like complex language, art (like cave paintings!), and strong communities.
- Brain Power: Our brains became much larger and more complex over time.
- Tool Use: We moved from simple rock tools to crafting complex objects.
- Migration: *Homo sapiens* were the final group to spread all over the entire globe!
- Thinking: We developed the ability to think abstractly, plan for the future, and create culture.
Even though Neanderthals (*Homo neanderthalensis*) lived at the same time as early *Homo sapiens* and were very strong, they eventually died out about 28,000 years ago, leaving our species, Homo sapiens, as the only humans left on Earth today!
