The landscape has changed from the birch and pine forest of the early postglacial to the oak and ash and elm forest of the later Mesolithic to the cultivated and grazed land of the present.

The species that share the British landscape have changed — aurochs are extinct, wolves are extinct, bears are extinct, beavers have been partially reintroduced after centuries of absence.

The people have changed beyond recognition — not just in appearance, as the Cheddar Man finding illustrates, but in language, culture, social organization, technology, and every other dimension of human life.

And yet the limestone of the Mendip Hills has not changed.

The cave is the same cave.
