Geostudies

Do you know about Geostudies? It has been in existence since 1996, and has been delivering classroom and field based geological courses up to the present. In an environment, over the past twenty years, of shrinking academic educational/recreational opportunities for adult students, it has been a vehicle for their delivery, particularly in the Stroud and Gloucester areas. Geostudies is run by Dave Green, a self-confessed geological enthusiast, who simply likes to pass it on!
Lots of courses are available with full details on the website.
Dave writes, "We are short of a couple of people on an evening course which started last week on Volcanoes, held at the Chantry Centre, Thornbury, which promises to encourage lively debate, if last week’s session is anything to go by!
If you want to join this course or any other - contact Dave

Hair pins down Aboriginal origins

A lock of hair has helped scientists to piece together the genome of Australian Aborigines and rewrite the history of human dispersal around the world. DNA from the hair demonstrates that indigenous Aboriginal Australians were the first to separate from other modern humans, around 70,000 years ago. This challenges current theories of a single phase of dispersal from Africa.
While the Aboriginal populations were trailblazing across Asia and into Australia, the remaining humans stayed around North Africa and the Middle East until 24,000 years ago.
Only then did they spread out and colonise Europe and Asia, but the indigenous Aborigines had been established in Australia for 25,000 years. Australian Aborigines therefore have a longer claim to the land in which they now live than any other population known.

Origins of Metallurgy in Eurasia - 13th October

Bath and Camerton Archaeological Society, Thursday 13th October, BRLSI, Queen Square, Bath at 7.30 p.m.
‘All that Glitters: the Origins of Metallurgy in Eurasia’. This talk will be given by Ben Roberts, British Museum Curator of European Bronze Age,
Before joining the Dept. of Prehistory and Europe, Ben worked for a number of years on archaeological projects in Britain, France and Central America.  Recently he had particular responsibilities for researching  and co-writing the first 40 programmes of the British Museum’s fascinating Radio 4 series ‘ A History of the World in 100 objects’. This lecture on the spread of Metallurgy from the Middle-East will address the question of when and where metal was first produced in Europe and Asia.
Everyone is welcome: visitors £4, members £2.

Feather evolution trapped in Canadian amber

Samples of 80 million-year-old amber in western Canada containing feathers from dinosaurs and birds have yielded the most complete story of feather evolution ever seen. Eleven fragments show the progression from hair-like "filaments" to doubly-branched feathers of modern birds. The find adds to the idea that many dinosaurs sported feathers - some brightly coloured.
Recent years have seen a proliferation of reports about the beginnings of feathers as we know them now in birds. So-called compression fossils found in China bear outlines of primitive "filament" feathers that are more akin to hair. But modern feathers are highly branched and structured, and the full story of how those came to be had not yet been revealed by the fossil record.
Now, a study of amber found near Grassy Lake in Alberta - dating from the Late Cretaceous period - has unearthed a full range of feather structures that demonstrates the progression.
