Copenhagen, European capital, international city of culture.

Here you can find people from all over the globe, over 600,000 of them, from all of Earth's nations.

But let's turn the clock back, back to a time when there were no nations,

back to a time when there were barely 600,000 people in the entire world.

To a time of immense cold, of tractless wilderness, and a constant, ever-pervasive battle against the elements.

Let's go back 15,000 years, to a time where no people lived in Scandinavia.

Humans had lived in Europe before this time.

Not quite the Homo sapiens who walk the earth today, but close enough to be recognisable.

Homo Neanderthalis, better known to us as the Neanderthals.

Fossil evidence suggests that the Neanderthals died a slow death, leaving their genes behind,

however, in modern Europeans, before they disappeared entirely.

Next came Cro-Magnons, distinct from their Neanderthal forebears by their use of weapons and tools,

and increased social skills. Though they too disappeared before long,

driven south by encroaching walls of ice from the north. For this, some 25,000 years ago, was the latest cold event of the last ice age.

For close to 10,000 years to come, much of Northern Europe found itself coated in a thick

layer of inhospitable glacial ice.

Finally, by around 15,000 years ago, a warm climate period started to begin, freeing up adventurous

groups of people to begin venturing north.

Little by little they pushed ever onwards into the fertile grasslands cleared up by the passing

of the ice. Let us follow one such group as they journey

into this unknown wilderness, filled with giant woolly mammoths and wild horses.

Yet it was not these great beasts who brought the earliest inhabitants of Denmark to the
