“…Early selection for “immunological competence” in small‐scale societies has been suggested as the reason age‐at‐death distributions are so different (Lovejoy et al, 1977, p. 293). Other explanations include the many hazards faced by young hunter‐gatherers (Bernardi et al, 2020; Flensborg et al, 2015), accidents suffered by middle‐aged adults in American southwestern pueblos (Palkovich, 1980), as well as generally poor conditions in medieval Italy and Japan (Baldoni et al, 2016; Gnes et al, 2018; Nagaoka et al, 2006), Iron Age Spain (Alesan et al, 1999), and Mesolithic to medieval Sweden (Welinder, 2001). In Andean Tiwanaku, old people moved, or their bones were carried, back to their original homeland, a contorted way to account for their apparent absence (Baitzel & Goldstein, 2016).…”

Much of paleodemography, an interdisciplinary field with strong ties to archaeology, among other disciplines, is oriented toward clarifying the life experiences of past people and why they changed over time. We focus on how human skeletons contribute to our understanding of preindustrial demographic regimes, including when changes took place that led to the world as we know it today. Problems with existing paleodemographic practices are highlighted, as are promising directions for future work. The latter requires both better age estimates and innovative methods to handle data appropriately. Age‐at‐death estimates for adult skeletons are a particular problem, especially for adults over 50 years that undoubtedly are mistakenly underrepresented in published studies of archaeological skeletons. Better age estimates for the entirety of the lifespan are essential to generate realistic distributions of age at death. There are currently encouraging signs that after about a half‐century of intensive, and sometimes contentious, research, paleodemography is poised to contribute much to understandings of evolutionary processes, the structure of past populations, and human‐disease interaction, among other topics.

“…En un estudio basado en el análisis sexo-etario de los entierros EA-1, H-4, H6-1, H6-3 y H7, Bernardi et al (2020) identificaron 75 individuos, con una representación levemente mayor de masculinos. La distribución etaria de la muestra se corresponde con una curva de mortalidad atricional, con dos picos de mortalidad, uno para infantes menores a un año de edad y otro para adultos jóvenes.…”

El análisis tafonómico permite conocer el origen y las posibles causas de la preservación diferencial en restos óseos. Este conocimiento resulta de suma utilidad para abordar análisis bioarqueológicos, ya que proporciona información clave sobre los procesos de formación del registro bioantropológico y de las condiciones ambientales del pasado. Este trabajo se centra en el estudio de los procesos y agentes post-depósitacionales de origen no antrópico que actuaron en el sitio Médano Petroquímica, un sitio con entierros prehispánicos (entre 419 ± 46 AP y 363 ± 45 AP) ubicado al sudoeste de la provincia de La Pampa, Argentina. Se realizaron análisis tafonómicos en restos óseos humanos correspondientes a 19 individuos recuperados de un entierro primario simple y tres entierros secundarios múltiples. Se contabilizaron 4179 especímenes correspondientes a 1829 elementos. Los resultados muestran que los entierros múltiples fueron afectados de manera similar por las distintas variables consideradas. Aunque la meteorización fue la variable registrada con mayor frecuencia, la acción de raíces habría sido la que mayormente afectó la integridad de los elementos. Esta experiencia pretende destacar la importancia del análisis tafonómico en los entierros humanos para obtener información acerca de la influencia del ambiente en el registro bioarqueológico.
