Demystifying the origin of the highly divergent chloroplast sequence found in Mexican archaeological sunflower remains

Sunflower sample

A crop domestication center emerged ~5000 years ago in Eastern North America. Native Americans in this area transformed several wild plant species, including sunflower (Helianthus annuus) into staple crops. Archaeological evidence from Eastern North America and genomic evidence from extant cultivated and wild sunflower supports this narrative, and it was once thought that cultivated sunflower did not reach Mexico until after European colonizers established trade routes.

Graduate Student

Martha is a PhD candidate who conducts bioarchaeological research. She received her BA from CSU, Fresno and her MA at CSU, Chico. At the PhD level she hopes to address questions regarding structural violence and how said violence can be seen on the skeleton, especially of those who attempt to cross the U.S./Mexico border.
