Una historia masticada: lo que cuentan los dientes de la conquista de México

The talk provides a compelling and accessible introduction to the use of dental microwear analysis in bioarchaeology, specifically applied to the study of post-conquest Mexico. The speaker, Nico Cirotto, is clearly knowledgeable and passionate about his research, and he effectively communicates the potential of dental evidence to reveal dietary patterns and population movements. The historical context is presented accurately, though simplified, and the emphasis on the often-overlooked African and Asian contributions to the mestizaje is a valuable corrective to the traditional narrative. The explanation of dental microwear is clear, with helpful analogies (e.g., comparing teeth to a safe) and visual aids (e.g., images of pits and scratches). However, the talk is primarily a popular science presentation, and as such, it lacks the rigor of a formal scientific lecture. No specific studies or data are cited, and the methodology is described only in general terms. The speaker mentions the AdMEXture project but does not provide details on its design, sample size, or preliminary findings. The discussion of dental microwear is somewhat superficial, omitting potential confounding factors such as taphonomic processes or the influence of food processing techniques. The title is well-matched to the content, and the talk successfully conveys the idea that teeth can tell a story about historical events. The presence of a brief sponsorship segment (approximately 30 seconds) is noted but does not detract from the scientific content. Overall, the talk is informative and engaging for a general audience, but it would benefit from more specific references and a deeper exploration of the methodology and its limitations.

The title is catchy and accurately reflects the content: the talk uses dental evidence to discuss the conquest of Mexico and the resulting gastronomic and biological mestizaje.

7/10

The talk is based on ongoing research (AdMEXture project) and mentions established methods (dental microwear, odontometry, isotopes, DNA). However, it is a popular science presentation with limited depth and no direct citations to specific studies.
