Debating scientific dating

A new technique for dating cave art pushes the earliest works back to at least 41,000 years ago and raises the possibility that Neandertals were responsible for some of it.

The B·Debate calendar of activities is carried out by means of a public call which invites proposals from the best research centres and researchers in the country, and it combines closed debates for small groups of specialists, symposia open to the scientific community, and conferences and talks open to the general public.

at the foot of Ben Nevis, and in the principal valleys, I discovered the most distinct morains and polished rocky surfaces, just as in the valleys of the Swiss Alps, in the region of existing glaciers; so that the existence of glaciers in Scotland at earlier periods can no longer be doubted.” These discoveries initiated new debates about climate change and the extent to which the actions of glaciers had been important in shaping the British landscape.

These arguments continued for the rest of the century.

It shows the narrow highway snaking through a rock-strewn Hell’s Glen not far from Loch Fyne.

Even though Buckland had already recognised glacial features in Dumfriesshire earlier that month, it can be argued that this was the first glacial fieldtrip in Britain.

Figuring out the age of cave art is fraught with difficulties.

Radiocarbon dating has long been the method of choice, but it is restricted to organic materials such as bone and charcoal.

Now dating experts working in Spain, using a technique relatively new to archaeology, have pushed dates for the earliest cave art back some 4000 years to at least 41,000 years ago, raising the possibility that the artists were Neandertals rather than modern humans.
