Common Geology: Common ground?

Newfoundland, England and the foothills of the Andes share common bedrock. The remnants of ancient continents connect now distant lands: the primal continent of Ur now arises fractured among India, Australia and Antarctica; other continental remnants link North America and Greenland, as well as South America and West Africa. What commonalities might these rocks imbue? In plants, in people? Using OneGeology technology http://www.onegeology.org and integrating stories of plants, animals and people, we explore the effect of ‘our common ground’.
