Human occupation of Britain was interrupted and renewed as prehistoric climates changed.
Across hundreds of thousands of prehistoric years, climate, food supplies and changing connections to continental Europe shaped whether humans could reach Britain—and remain.

Warmth was not enough
Around 125,000 years ago, hippopotamuses inhabited the Thames, yet Britain apparently lacked humans. The contrast is instructive: a congenial climate was insufficient if rising seas had cut off the route from continental Europe.
Prehistoric settlement depended on both conditions and connections. Climate altered food supplies and habitable territory; sea levels helped determine access. Cold could make the land inhospitable even as falling seas exposed routes into it. Britain’s human history was therefore no simple alternation between welcoming warmth and empty, frozen landscapes.
Footprints, then long silences
At Happisburgh in present-day Norfolk, footprints roughly 850,000–950,000 years old preserve an exceptionally early human presence. Probably left by adults and children crossing estuarine mud, they belong to people whose species remains unidentified. They were not Homo sapiens; Homo antecessor is one possibility.
Much later, between approximately 180,000 and 60,000 years ago, Britain’s archaeological record contains no known human remains or tools. Severe cold, followed by isolation behind rising seas, helps explain this substantial gap. Neanderthals returned around 60,000 years ago, when lower sea levels again exposed continental connections.
Such silences strongly suggest abandonment, rather than demonstrating that nobody survived anywhere. Nor did every cold period exclude humans: tools from glacial-stage deposits at Old Park, Canterbury, reveal a capacity to endure conditions that a tidy climatic timetable might overlook.
Returning was not yet remaining
Our own species was present at least 40,000 years ago, with a jaw fragment from Kent’s Cavern in Devon providing early direct evidence. Occupation remained sporadic. Another disappearance came around 25,000 years ago as conditions deteriorated towards the last glacial maximum, when ice covered much—but not all—of Britain.
Renewed occupation around 15,200 years ago was linked to regional summer warming and available prey. That return should not be mistaken for uninterrupted settlement: continuous occupation is placed later, with the climatic improvement ending the last Ice Age, around 9500 BC. Ancient DNA also reveals distinct incoming populations—a history of successive arrivals, not an unbroken national ancestry.
