Humans habitually categorize things they think about. 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.

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.

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. It’s a natural and cultural treasure most of us don’t know enough about.

SGA members are concerned about predictions of global increases in sea level because Georgia’s coast has many archaeological sites, including shell mounds and historic buildings, that are right at sea level or only a few feet above sea level. 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.

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.

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.

Archaeologists seeking to reconstruct past lifeways rely for their interpretations on the timeworn remains of ancient cultures for guidance; here in our humid Georgia climate, we are further disadvantaged since often only the inorganic residues of prehistoric culture remain. The study of stone tools, sherds of pottery, and the scant remnants of organic items and [...]
