What is this lesson about?

Some people believe that a god or gods created the first humans. Scientists say that it took millions of years before people evolved into what we are now. 

Archeologists and paleontologists have found bones of the first humans in Africa. 

Modern humans are called Homo Sapiens and they didn’t stay in Africa. Instead, they spread all over the world.

What you will learn in 

this lesson

• what a creation narrative is
• what the evolution theory is
• how both theories are used to explain where humans come from
• what the "Out of Africa" theory means
• how you can  read the family tree of   modern humans
• what paleontologists and archeologists do

Word Duty

1.1 First humans

Fossils: remains of plants or animals that are preserved in stone

Scientist: someone who studies a science, for instance history, physics or biology

Creation narrative: a story that says God created man and the rest of the world

Theory of evolution: theory written by Charles Darwin to explain the way species change

Excavation: process by which you uncover something through digging away the earth that covers it

Paleontologist: someone who studies ancient life on the planet

Archeologist: someone who digs up remains to investigate human activity in the past

Tool: an object held in one hand to accomplish a task (for example: an axe)

Out of Africa theory: theory that modern man evolved in Africa and then migrated to 

other areas in the world

KEY WORDS

Timeline of this AGE

Introduction

Wherever you live on earth, we are all humans. But where do we come from? And

how did our ancestors live? We will start our study of the past by learning something

about the origins of mankind.

Lucy

Our trip starts near the small village of Hadar in Ethiopia. On a very hot day in 1974, two men were looking for fossils. Fossils are remains of plants or animals that have turned into stone. Many fossils can be found in Ethiopia and in the Great Rift Valley in Africa.

The men were scientists interested in early humans. Their search was a success, because they discovered some old and very special bone pieces.

The bones were from a skeleton that was 3.2 million years old! At first, the scientists thought the skeleton was from a small female chimpanzee. But when they looked closer, they saw that this animal could walk on two legs. The scientists were very happy because they had found the oldest skeleton of an early human in the world!

The female human skeleton that was found was named Lucy. She got this name from the song 'Lucy in the sky with diamonds'. This song was played during the discovery and was a popular song by The Beatles in the seventies.

 This is probably how Lucy looked, when she was still alive. Why was this one of the most important discoveries in the history of mankind? (present-day drawing).

Where do humans come from?

For thousands of years, people thought a god or gods created humans. A famous example is the story of Adam and Eve. God made them, and they lived in paradise until they ate from the forbidden tree. This story is called a creation narrative.

But scientists have a different idea about how humans started. They studied Lucy's bones and learned that the first humans lived in Africa. These early humans looked very different from us. Still, scientists say they were our ancestors because they walked on two legs. So, they must have changed to become like us. How is that possible?

Theory of evolution

This was also a very important question for the biologist Charles Darwin around 1850. On his travels, he found out that species change over time. They adapt to their environment to survive. A polar bear is white because it lives in the snow, and a giraffe has a long neck to eat leaves on tall trees. This process of adaptation can take millions of years.

Darwin's idea is called the theory of evolution. He also said that humans and apes have the same ancestors. It took three million years for these first humans to change into the people we are today. In the family tree below, you can see the different human-like ancestors that used to live.

Charles Darwin, 1809 - 1882

This is the human family tree, with the different species of early humans.

The Latin word Homo means ‘man’. When we talk about humans we use this word. For example: Homo habilis was ‘the tool using man’ and Homo erectus ‘the upright man’. We modern humans are Homo sapiens sapiens which means ‘very wise man’.

Archeology and Paleontology

What we know about evolution comes from fossils and bones like Lucy’s, that were discovered by a team of different scientists. At Lucy’s excavation there was a paleontologist, someone who studies ancient life on the planet. These paleontologists investigate fossils that can be millions of years old. There was also an archeologist, a person who digs up remains to investigate human activity in the past. Every new discovery helps us to determine how humans have evolved.

Out of Africa

Modern humans evolved differently from apes. The first humans started to walk upright. This left their hands free to use tools. Tools are objects held in one hand to do a task, like a sharp rock to cut meat. They also learned to use fire.

Around 250,000 years ago, Homo sapiens evolved in Africa. This species left Africa and spread all over the world. This did not happen all at once. It took place between 250,000 to 56,000 years ago and is called the Out of Africa theory. According to this theory, modern humans evolved in Africa and then moved through the Middle East to Asia, Europe, and the Americas. Homo sapiens were very good at adapting to changes in their environment, like different landscapes and changing climates. This ability to adapt might be why Homo sapiens survived while other human species did not.

The spreading of humans across the world.

The discovery of Lucy was not the only important one in Ethiopia. In 1994, a group of paleontologists discovered the remains of a 4.4 million year-old skeleton. They called it 'Ardi'. Scientists are still debating if Ardi is human or ape. Some believe that her specie is 'the missing link' between us and apes.
