“Diving into the Archaeological Mystic – A Taíno Underworld and Sacred Landscape in the Caribbean”
by
John Foster
Saturday, July 13, 2024
2:00 PM – 3:30 PM PT

John Foster, past-president of SAS, retired California Senior State Archaeologist, and Adjunct Faculty at Indiana University will discuss a fascinating submerged archaeological site in the Dominican Republic. Working with underwater archaeologists and Dominican National Park specialists, a deep water sinkhole was documented and selected artifacts were recovered some 27 years ago. In a remote setting deep within the tropical forest, Manantial de la Aleta proved to be a Taino offering site with excellent preservation conditions that allowed a deeper understanding of Taino culture and beliefs. It remains the only “cenote” known from the Caribbean.

The presentations will be presented at Young Hall, Room 224 and available via Zoom. The webinar will start at 2:00 PM PT and formally conclude at 3:30 PM. You may join starting at 1:45 PM to say “Hello” and participate in a social time.

“A tale of two teosintes: how genetics is reshaping our understanding of maize domestication”
by
Jeffrey Ross-Ibarra
Saturday, May 11, 2024
2:00 PM – 3:30 PM PT
We are pleased to have a Jeffrey Ross-Ibarra, Evolutionary Biologist at University of California, Davis discuss his research in the evolution and adaptation of maize.

Abstract: The widely accepted narrative of maize domestication posits a single origin from the wild grass Zea mays ssp. parviglumis (lowland teosinte) in southwest Mexico, likely beginning with de novo mutation at an important gene controlling kernel architecture. However, recent genomic surveys challenge this simplicity, revealing evidence of gene flow from another wild relative, Zea mays ssp. mexicana (highland teosinte). Here we demonstrate widespread hybridization between maize and highland teosinte across time and geography, suggesting a revised model of maize origins in which maize hybridized with teosinte in the central Mexican highlands around 4000 years post-domestication. We also revisit the origin of the important domestication gene tga1, using population genetic analysis and simulations to show that relevant diversity at this key locus likely predated domestication, highlighting the importance of adaptation from pre-existing genetic variation. Together, our findings challenge existing models of maize evolution and illustrate domestication as a complex evolutionary process rather than a single event.

Jeffrey Ross-Ibarra is an evolutionary biologist who uses computational and genetic approaches to understand the evolution and adaptation of maize and its wild relatives. Dr. Ross-Ibarra’s undergraduate and early graduate background in ethnobotany has long influenced his interest in the coevolution of humans and their crop plants. More about Dr. Ross-Ibarra’s work can be found at his website rilab.ucdavis.edu.

The presentations will be presented at Young Hall, Room 224 and available via Zoom. The webinar will start at 2:00 PM PT and formally conclude at 3:30 PM. You may join starting at 1:45 PM to say “Hello” and participate in a social time.

“Finding Evidence for Ancient Maya Canal Use at Rio Azul, Guatemala”
by
Emily Johnson, UC Santa Barbara PhD Student
Saturday, April 13, 2024
2:00 p.m. – 3:30 p.m. PST

Emily will discuss her research of ancient plant remains in Guatemala and Belize. The result of this research is to better understand the agriculture of this Central American region and how practices may have changed over a period of 2000 years. Emily received a scholarship from SAS to collect soil samples and then analyze them for macrobotancial remains such as starch granules and phytoliths.

The presentations will be conducted via TEAMS. The webinar will start at 2:00 PM PT and formally conclude at 3:30 PM. You may join starting at 1:45 PM to say “Hello” and participate in a social time.

On March 9 via Zoom we are pleased to have two of our 2023 scholarship recipients talk about the field school that they attended.
2:00 – 2:30 PM PT – “Gallina Field School” by Noor Sullivan, University of Maryland, College Park
2:45 – 3:30 PM PT – “Blackfriary Archaeological Field School” by Brianna Ramirez, New Mexico State University

“Gallia Field School” by Noor Sullivan, University of Maryland, MPS in Cultural Heritage Resource Management student
Noor is interested in community-collaborative cultural resource management and
programming, particularly among indigenous communities. To this end he is enrolled in the Cultural Heritage Resource Management program at University of Maryland. In order to move his career interests forward by experiencing archaeological methods and being introduced to indigenous communities of New Mexico, he chose to attend the Gallina – Puebloan Rebels of the Southwest Field School. Noor will give a presentation on experiences at this field school.

“Blackfriary Archaeological Field School” by Brianna Ramirez, New Mexico State University recent graduate
This past summer, Brianna attended the Blackfriary Archaeological Field School in Ireland. This school provided a summer course on field work for bioarchaeology and post-excavation methods. Since Brianna is interested to become a forensic anthropologist this field school was signification because of the director’s commitment to ethics in the analysis and treatment of human remains and a dedication to community engagement and heritage. Brianna will discuss her experiences at the field school.

“Meadowcroft Rockshelter: Archaeological Excavation Challenged Clovis-First Peopling Model”
by
Dr. James M. Adovasio, Archaeologist, Primary Investigator
Introduced by Phil Fitzgibbons, Participating Archaeologist
Saturday, February 10, 2024
2:00 p.m. – 4:00 PM PT
James. M. Adovasio, Ph.D., D.Sc. achieved world acclaim as an archaeologist in the 1970s with his excavation of Pennsylvania’s Meadowcroft Rockshelter. Meadowcroft is widely recognized as one of the earliest well-dated archaeological sites in North America, with evidence of human habitation dating to ca. 16,000 years ago. Perhaps, more importantly, Meadowcroft is considered to be one of the most meticulous excavations ever conducted, anywhere. During his career, he has specialized in the analysis of perishable materials (basketry, textiles, cordage, etc.) and the application of high-tech methods in archaeological research. In recent years, his research has confronted another of archaeology’s mysteries by delving underwater to seek submerged evidence of early Americans off the coast of Florida in the Gulf of Mexico. Recently, he was the principal investigator of the re-excavation at the Old Vero Man Site in Florida. This Late Ice Age locality has figured prominently in the history of American Anthropology and promises to yield new insights into the behavior of the First Floridians. He is the author of more than 500 books, book chapters, monographs, articles, and papers which include “The Invisible Sex: Uncovering the True Roles of Women in Pre-History,” “The First Americans: In Pursuit of Archaeology’s Greatest Mystery,” and “Basketry Technology,” and most recently “Strangers in a New Land.” Adovasio received his undergraduate degree in anthropology from the University of Arizona and doctorate in anthropology from the University of Utah. He is formerly the Director of Archaeology at Harbor Branch Oceanographic Institute, Florida Atlantic University and currently Director of Archaeology at Senator John Heinz History Center, Pittsburgh, Pennsylvania.

“Varsche Rivier 003, a middle aged rock shelter in southern Namaqualand, South Africa”

Patricia McNeill, a 2022 scholarship recipient has been investigating hunter-gatherer mobility and resource catchment area in the arid Knersvlakte of Namaqualand, Western Cape, South Africa. In this dissertation research she is in the process of examining ostrich eggshell beads from the site and analyzing waste fragments of shells that were discarded after eating the egg in order to reconstruct mobility and paleoclimate. In this presentation she will cover the most recent discoveries from VR003, her investigation area. One of the tools she uses to analyze mobility of Stone Age people in the region is radiogenic strontium isotopes. Strontium isotopes (⁸⁷SR/⁸⁶SR) can be used as a tracing tool for biogenic materials, such as teeth, bone, and egg shells. This analysis is not yet complete.

Patricia McNeill is a PhD candidate at University of California, Davis. She received her B.A. Summa com laude Evolutionary Anthropology and M.A. at University of California, Davis. She has conducted extensive research at the Center for Experimental Archaeology at Davis. Her field experience includes Varsche Rivier 003, Namaqualand, South Africa, Ranis, Saale-Orla Kreis, Thüringen, Germany and Bureau of Land Management, Eagle Lake Field Office, California. She has four publications.
