AnthroBiology Podcast Dr. Maria Nieves-Colón and Jaime Zolik, MA – Working with Ancient DNA and descendent communities in Peru
Dec 3, 2025
Dr. Maria Nieves-Colón, a biological anthropologist at the University of Minnesota, and graduate student Jaime Zolik delve into their groundbreaking work with ancient DNA in San Luis de Cañete, Peru. They explore the historical African diaspora and highlight ethical community engagement in their research. Fascinatingly, they discuss dental modifications reflecting African cultural ties and uncover high African diversity through mitochondrial DNA analysis. The duo passionately shares their commitment to involving community members in the research process while fostering educational outreach.

Episode notes
Minimize Destructive Sampling
- Minimize destructive sampling and discuss material choice with descendant communities before extraction.
- For this project they sectioned teeth and used a Dremel to remove only necessary dentin, preserving most of each tooth.
One Sample Can Reveal Host And Pathogens
- Teeth pulp yields host DNA plus potential bloodstream microbes, letting researchers study both ancestry and pathogens.
- Enrichment capture methods act like baits to fish human or pathogen fragments from a sea of microbial DNA.
Keep Labs Clean And Community Visible
- Use a clean, UV- and bleach-treated ancient DNA lab with positive pressure to avoid modern contamination.
- When samples must be processed offsite, keep communities informed using recorded videos and transparent documentation.
