NEXT MEETING: Wednesday, August 17, 2022, 7PM, online via Zoom: 7:00 PM: The GCAS welcomes West-Mexican archaeologist Manuel Dueñas Garcia as our Featured Speaker. As usual for our Zoom meetings we invite everyone to hop online about 6:45 PM to get settled while we have a brief-to-nonexistent business meeting. Manuel will begin his presentation at 7PM sharp to share his perspectives on Aguascalientes Archaeology and the Northern border of Mesoamerica during the Epiclassic (600-900 CE). Members, check your email about a week prior to the meeting to receive your Zoom link. We'll see you online as Manuel discusses new insights about our region.

NEXT FIELD TRIP: TBA but meanwhile, remember that to protect vulnerable resources we offer our field trips to members only. Members’ invited guests are welcome, as long as they ride in that member’s vehicle.

New Techniques in the Study of Human Remains

image from abm-website-assets.s3.amazonaws.comResearchers have discovered that a certain protein in tooth enamel comes from a sex-specific gene. Scientists at the University of California/Davis have taken that discovery and developed a technique by which they can determine the gender of human remains even if only a single tooth is all that is recovered. Details are in this recent article in Archaeology magazine.

This technology is potentially a great help to archaeologists, including those who study our area of the US Southwest, because the recovery of a single tooth that is not associated with any other human remains may now yield more valuable and relevant information about a given archaeological site than ever before.

Science is so cool.
