This includes time, which we divide into segments such as pre- and post-war, the Mississippian period, etc. Several geologists argue that we should refer to the Epoch we're living in now as the Anthropocene, to highlight the changes the world is undergoing that are introduced and exacerbated by human behavior.]]> http://thesga.org/2010/04/whats-in-a-name/feed/ 0 http://thesga.org/2010/02/archaeogenetics-summarized-in-current-biology/ http://thesga.org/2010/02/archaeogenetics-summarized-in-current-biology/#comments Fri, 26 Feb 2010 10:00:57 +0000 sammy http://thesga.org/?p=5064 Global Genetic History of Homo sapiens is the title of a new special issue of Current Biology, with eight papers available free online. This topic is also called archaeogenetics. There's an introductory and a summary article, which bracket six articles that focus on human migration in specific geographic areas, including the New World.]]> http://thesga.org/2010/02/archaeogenetics-summarized-in-current-biology/feed/ 0 http://thesga.org/2009/12/jekyll-island%e2%80%99s-hidden-past/ http://thesga.org/2009/12/jekyll-island%e2%80%99s-hidden-past/#comments Mon, 07 Dec 2009 06:00:50 +0000 sammy http://thesga.org/?p=4518 Georgia's Jekyll Island has an interesting past, detailed here. The Island is owned by the the people of Georgia and managed on their behalf by the Jekyll Island Authority.

Therefore, changes in water levels will damage fragile archaeological resources. The full story examines some of the factors involved in generating a good model of the coming changes in sea level.]]> http://thesga.org/2009/12/building-better-climate-change-models/feed/ 0 http://thesga.org/2009/11/how-did-climate-change-affect-pleistocene-megafauna/ http://thesga.org/2009/11/how-did-climate-change-affect-pleistocene-megafauna/#comments Fri, 27 Nov 2009 10:00:02 +0000 sammy http://thesga.org/?p=4187 Read the full story for a discussion about what recent ecological reconstructions based on fossil pollen, charcoal and dung fungus spores tell us about the end of the Ice Age in interior North America.]]> http://thesga.org/2009/11/how-did-climate-change-affect-pleistocene-megafauna/feed/ 0 http://thesga.org/2009/06/climate-change-and-georgias-archaeological-resources/ http://thesga.org/2009/06/climate-change-and-georgias-archaeological-resources/#comments Fri, 19 Jun 2009 09:00:51 +0000 sammy http://thesga.org/?p=3326 This week our federal government released a report on global climate change that says in part, "Likely future changes for the United States and surrounding coastal waters include more intense hurricanes with related increases in wind, rain, and storm surges (but not necessarily an increase in the number of these storms that make landfall), as well as drier conditions in the Southwest and Caribbean." These changes will affect Georgia's archaeological heritage.]]> http://thesga.org/2009/06/climate-change-and-georgias-archaeological-resources/feed/ 0 http://thesga.org/2001/05/reconstructing-the-past-archaeology-and-experimentation/ http://thesga.org/2001/05/reconstructing-the-past-archaeology-and-experimentation/#comments Sun, 20 May 2001 21:45:22 +0000 sammy http://thesga.org/?p=1360 http://thesga.org/2001/05/reconstructing-the-past-archaeology-and-experimentation/feed/ 0
