The fossil record stays silent: Confusions and conundrums for hominin pelvis evolution
Abstract The evolution of the hominin pelvis is commonly modeled as a series of stages driven largely by the requirements of bipedal locomotion, reproduction, thermoregulation, and pelvic floor muscular support. These patterns are complicated by variation in canal dimensions in relationship with different changes in overall pelvic breadths. To quantify

Ubicación cefalométrica del hueso hioides en pacientes respiradores bucales
El hioides es un único hueso “flotante”, que no posee articulaciones óseas, ni relación de unión con las vértebras cervicales. Este hueso actúa como arco que nivela los músculos agonistas y antagonistas de la masticación y además es utilizado como ...

ABSTRACT Long‐term cultivation can improve soil health, but recovery may not follow the same pathway across contrasting soil and climate conditions. A key unresolved question is whether soil health recovery is mainly associated with the release of physical–chemical constraints or with the gradual rebuilding of carbon, microbial biomass, and nutrient ...

Our current understanding of the origins of Homo sapiens is limited, in part, by the fragmented fossil record from Late Pleistocene and early Holocene Africa. Here, we re‐examine the Kabua 1 cranium, an enigmatic and little‐studied Kenyan fossil discovered in the 1950s. We compare virtual reconstructions created previously by our team with a wide range

Enfoque de la osteosarcopenia: dos síndromes geriátricos superpuestos
Contexto: la osteosarcopenia es un término utilizado desde el año 2009 que se refiere a la coexistencia del deterioro de la microarquitectura ósea (osteopenia/osteoporosis) y el compromiso muscular (sarcopenia), dos síndromes geriátricos prevalentes en ...

This article presents a synthesis of recent developments in the study of human evolution over the past five years. It begins with an overview of hominin species nomenclature and diversity, followed by an examination of the proposed population bottleneck ∼900,000 years ago.

The year 2025 marked the ninetieth since a fossil hominin occipital bone was discovered in Swanscombe, southeast England. In subsequent years, its parietal bones were found, producing what remains the oldest partial cranium from Britain today. In the earliest analyses, it was interpreted as a descendant of the infamous fraudulent fossil Piltdown Man ...

Recent archaeological discoveries, reviewed in this essay, challenge traditional views on the emergence of human symbolic cognition. Once believed to have originated in Europe around 40,000 years ago, new evidence shows it emerged much earlier across diverse regions.

Estudio de la estabilidad en implantes insertados en hueso nativo y hueso regenerado [PDF]
La osteointegración está determinada clínica e histológicamente por la estabilidad de los implantes. La obtención de una elevada estabilidad primaria de los implantes en el momento de su inserción, así como su mantenimiento a lo largo de todo el ...

The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the
