The dominant model links ape suspensory anatomy to ripe fruit feeding in terminal canopies, but new evidence shows positional versatility reflects interacting ecological factors, challenging single-factor adaptive explanations of hominoid evolution

Research on Hungarian Neolithic skeletons show shifting gender roles over time. Early burials show little sex distinction while later communities display gendered practices—yet skeletal stress markers reveal flexibility and individual variation #ajba

Not all bones record the same isotopic history. This bomb-carbon study shows large differences in collagen turnover across skeletal elements, refining how stable isotope data should be interpreted in archaeology and paleoanthropology

Arboreal bipedalism is hypothesized to precede terrestrial bipedalism, but biomechanical data are scarce. This study presents a captive experimental protocol that increases occurrence and enables gait analysis for evolutionary comparisons

Maternal mtDNA from 168 Gujaratis shows continuity of indigenous lineages since the Pleistocene. Indo-Aryan & Dravidian migrations had minimal maternal impact, while gene flow with West Eurasia did not cause large-scale population replacement

This study reviews, updates taxonomy, and digitizes the archival data of Mozambique’s non-human primate collection at the National Museum of Natural History and Science (Lisbon), assembled during Portuguese zoological missions in 1948 and 1955.

Comparisons of StW 573 & MLD 1 show they do not share the diagnostic traits needed for a species match. StW 573 differs in key cranial features, while MLD 1 resembles classic A. africanus. Therefore, StW 573 should not be attributed to A. prometheus

Locomotion is central to human survival, but in adolescents, preferred walking speeds aren't always the most energy-efficient. Greater walking flexibility reduces energetic penalties, and may offer adaptive advantages in human evolution.

Bio anth often treats populations as key units of evolution, but the term is used inconsistently. There is variation in how populations are defined (sample sizes, time ranges, characteristics), making comparisons hard. Clearer definitions are needed

This study integrates evolutionary theory into forensic practice to improve how sex is estimated from skeletal remains. By accounting for morphological integration, sex estimation can be accomplished with less variables without compromising accuracy

At Roonka, Australia, osteoarthritis wasn’t the ‘inevitable’ part of aging we assume today. Rare before European contact, OA here reveals how local biocultural entanglements shape the body, challenging ideas of universal biology

The terminal Pleistocene was key in shaping modern populations, marked by high variability & regional divergence. Yahuai-1 (YH1;~16kya, southern China) offers insight into human diversity & population dynamics in SE Asia during this pivotal time

Racial disparities in birth & breastfeeding persist among non-Hispanic Black women. This study found labor mismatch (birth intent vs outcome) didn’t affect breastfeeding but income, education & BMI can impact women meeting birth & breastfeeding goals

Epidemiologic research suggests sedentism increases irritable bowel syndrome (IBS) risk. This study suggests IBS may be driven by longitudinal effects of exercise alongside other environmental and behavioral factors contributing to energetic balance

As ethics evolve globally, there is growing pressure on paleoanthropology to revisit its ethical practices, help create globally informed standards, and better align fossil handling with practices in related fields, such as human tissue research

This study investigates enamel thickness among Atapuerca hominins. The results caution against using enamel thickness alone for taxonomic classification and emphasize the importance of analyzing both upper and lower dentitions across dental classes
