Comparative Context of Hard-Tissue Sexual Dimorphism in Early Hominins: Implications for Alpha Taxonomy.
Evol Anthropol
March 2025
Center for the Advanced Study of Human Paleobiology, George Washington University, Washington DC, USA.
Article Synopsis
- Sexual dimorphism complicates the creation of alpha taxonomic classifications in early hominin fossils.
- The study explores factors influencing sexual dimorphism in primates, including body size differences, craniofacial traits tied to visual signaling, and growth patterns.
- Focusing on Paranthropus boisei, the study warns that focusing on skeleton regions affected by sexual selection can lead to inaccurate taxonomic assessments.
A sedimentary ancient DNA perspective on human and carnivore persistence through the Late Pleistocene in El Mirón Cave, Spain.

Caves are primary sites for studying human and animal subsistence patterns and genetic ancestry throughout the Palaeolithic. Iberia served as a critical human and animal refugium in Europe during the Last Glacial Maximum (LGM), 26.5 to 19 thousand years before the present (cal kya).

This commentary adds elements of analysis from the new evolutionary sociology that might help to support the mythologic hypothesis. It discusses the likelihood of a more generalized processer rather than exactly evolved psychological mechanisms, the consequences of bottlenecks, and the importance of utilizing molecular, fossil, and primate data in the authors' research program.

The time of integration of germline-targeting Long Terminal Repeat (LTR) retroposons, such as endogenous retroviruses (ERVs), can be estimated by assessing the nucleotide divergence between the LTR sequences flanking the viral genes. Due to the viral replication mechanism, both LTRs are identical at the moment of integration, when the provirus becomes part of the host genome. After that time, proviral sequences evolve within the host DNA.

A tooth-bearing mandible fossil of a colobine monkey discovered at Shuitangba, Zhaotong, Yunnan, China, was morphometrically analyzed and compared with extant Asian colobines. Our previous qualitative and quantitative descriptions indicate that it can be safely attributed to Mesopithecus pentelicus, a Miocene fossil colobine widely found in Europe and South Asia. The present research aims to explore fossil association with extant colobines and functionally propose its dietary preferences based on multivariate morphometric analyses of mandibular morphology.
