Scientists have identified the exact place where humans first walked the Earth.

The Australian-led team of scientists believes our original homeland lies to the south of the Zambezi River, in northern Botswana.

It is here that the earliest ancestors of everyone alive today probably arose* 200,000 years ago.

The region was then thought to be lush green and home to an enormous lake.

It allowed Homo sapiens to thrive in this one place for 70,000 years until climate change forced or allowed them to disperse*, either because they needed to find a better place to live, or as the land surrounding them that had been desert became hotter and wetter.

The move paved the way for humans to migrate out of Africa and then across the world.

Fossil finds had suggested humans arose in eastern Africa and genetic* analyses had hinted at southern Africa.

But new research has pinpointed the location to the Makgadikgadi wetlands.

The lake was twice the size of modern-day Lake Victoria* but the area is now largely desert and salt pans.

A global team of researchers used genetics*, geology* and physics* to map the bloodline* and the land.

Professor Vanessa Hayes, a geneticist from the Garvan Institute of Medical Research in NSW, said it was the first time the site has been located.

“It has been clear for some time that anatomically modern humans appeared in Africa roughly 200,000 years ago,” she said.

“What has been long debated is the exact location of this emergence and subsequent dispersal of our earliest ancestors.

“This is the first time the exact location has been identified.”

Our ancestors migrated out of the homeland between 130,000 and 110,000 years ago.

The first migrants ventured north, followed by a second wave that travelled south west. A third population remained.

The findings are published in the journal Nature.

  1. Describe where the Makgadikgadi wetlands was.
  2. How big was the Makgadikgadi wetlands? What is there now?
  3. Where did each of the three early populations of Homo sapiens go?
  4. How long ago did life begin on Earth?
  5. When did Homo sapiens evolve?


1. Puppet play
Work in small groups (3-4 students) to create a short and informative puppet play of how life evolved. Use the timeline in the Kids News article as your main source of information, choose who you think the main life forms are to represent in your play and divide up who is making which puppet (you could just draw a picture and use icy pole sticks to stick them onto).

Work together on a short script on how you present your puppets so you could teach students in other classes about how life evolved on Earth from your play.

2. Extension
A quote from the article stated that the huge lake “allowed Homo sapiens to thrive for 70,000 years until climate change forced them to disperse”. Homo sapiens is the scientific name for the human species. Compare and contrast how climate change back then might be similar or different to what we are currently facing on Earth in 2019, recording your findings in a two-column table with SIMILAR and DIFFERENT at the top of each column.

Dear diary
Imagine you are a part of the first migrants who ventured North to try and recolonise in another area.

Think about who you are. Why you are leaving? Do you have family coming with you? What supplies or tools might you have? Talk about your feelings as you prepare to leave to find a new home.

Just before you leave. Make your mark. Head into the local cave and leave a short cave picture to describe an event that caused you to leave or who you and your family are.

Draw your cave picture under your diary entry.

HAVE YOUR SAY: Where on Earth and when in history would you choose to live? Would you choose here and now?
