As late as the 1950s researchers were busy collecting data among Irish people such as hair colour and height, in order to categorise them as a 'race' and define them as different to the British.

In fact British and Irish people are closely related in their ancestry.

An evolutionary view of human origins underlies the World Heritage listing of the Lake Mungo site.

Such a view was not good for the first Australians.

The results provide conclusive evidence that the linen of the Shroud of Turin is mediaeval.

The Shroud of Turin , which many people believe was used to wrap Christ's body, bears detailed front and back images of a man who appears to have suffered whipping and crucifixion.

The size of the sample then required, however, was ~500cm, which would clearly have resulted in an unacceptable amount of damage, and it was not until the development in the 1970s of small gas-counters and accelerator-mass-spectrometry techniques (AMS), requiring samples of only a few square centimetres, that radiocarbon dating of the shroud became a real possibility. The shroud was separated from the backing cloth along its bottom left-hand edge and a strip (~10 mm x 70 mm) was cut from just above the place where a sample was previously removed in 1973 for examination.Photography of the shroud by Secondo Pia in 1898 indicated that the image resembled a photographic 'negative' and represents the first modern study.Subsequently the shroud was made available for scientific examination, first in 19 by a committee appointed by Cardinal Michele Pellegrino .by Tas Walker Darwin considered the Australian Aborigines as primitive and not much evolved from the ‘anthropoid apes’.He anticipated that the ‘wilder races’ would become extinct because survival of the fittest meant they would be superseded by the evolutionarily-advanced ‘civilised’ races.
