The rugged peninsula is positioned between North Africa, Europe and the Mediterranean on the westernmost edge of the continent, so the DNA of its ancient population shows how it was affected by migration over time.

Iberia was also relatively warm during the last Ice Age, between 18,000 and 24,000 years ago, presenting a more welcoming climate for animals and people who retreated from the rest of Europe.
