The long human story

Three lessons on the whole of human time: how long it is, the oldest pictures people made, and the moment some of them started writing things down.

The whole span of our species on one line, at true scale, in thousands of years ago. Each thin mark is a dated moment from these lessons; the red block at the right-hand end is the time since writing began. Almost everything happened before it.

  1. Lesson 1 · 315,000 years ago to now

    How long is human history?

    How much of the human story was ever written down?

    Our species’ whole story on one line at true scale, zooming in step by step.

  2. Lesson 2 · At least 67,800 years ago

    The first hands

    How can anyone tell how old a cave painting is?

    Hand stencils are among the oldest pictures people made. How a crust of stone dates them.

  3. Lesson 3 · 3400 BC to 200 BC

    Writing, invented four times

    Was writing invented once, or more than once?

    Writing began separately in at least four places. Where, when, and what the first writers wrote.

    Fits: Primary (KS2)

After writing

Writing is where this subject ends and the others begin. Roman Britain starts with a people who wrote things down, arriving among people who mostly did not.

Where experts disagree: are the oldest fossils really us?

Yes, an early form of our species.The faces and teeth of the people from Jebel Irhoud in Morocco, about 315,000 years old, fall within the range of people today. The team that described them calls them early members of Homo sapiens.1

Not quite, say others.Their braincases are longer and lower than ours, as the same team notes, and some researchers would rather call them close relatives of our species. Either way, the line on this page would only get a little shorter. Read more.1
