This timeline focuses on species of Homo and covers the Pleistocene from the first evidence of humans.
The names used for glaciations and interglacials are those with historic usage for Britain and may not reflect the full climate detail of modern studies.
Dates for the Paleolithic are given as Before Present (BP), which uses 1 January 1950 as the commencement date of the age scale. All later dates are given as Before Christ (BC), which uses the conventional Gregorian calendar with AD 1 as the commencement date of the age scale.
Rising sea-levels cut Britain off completely from the continent. It is warm enough for hippos in the Thames and lions on the site of Trafalgar Square, but Neanderthals did not cross the landbridge in time so there are no Homo sp. present.
The Holocene warming begins as the end of the Younger Dryas stadial ends the Pleistocene. The first Mesolithic people arrived and this marks the start of continuous human (Homo sapiens only) occupation.
