Human evolution and the obstetrical dilemma: The pelvic floor hypothesis
Abstract Human childbirth is mechanically difficult because a large‐headed, broad‐shouldered fetus must pass through a comparatively narrow, twisted bony birth canal. Traditional explanations of this “obstetrical dilemma” emphasize the role of bipedal locomotion in inhibiting the evolution of a wider, more spacious pelvis.

Abstract Factors varying along elevational gradients impose strong aerodynamic and physiological constraints on powered flight, yet the internal microanatomical variation associated with elevational context in animals under such conditions remains poorly understood.

Craniofacial growth, modeling, and estimation of milestones
Abstract Understanding craniofacial growth is foundational for research into intra‐ and interspecies variation, evolution, and clinical care. The Craniofacial Growth Consortium Study (CGCS), combines cephalographs from historical growth studies to create a dense longitudinal record of growth from 6 to 22 years of age.

Postnatal craniomandibular growth in Harbor seals (Phoca vitulina vitulina)
Postnatal ontogeny in Harbor seals (Phoca vitulina vitulina). Cranium and mandible grow rapidly until 5 years of age, followed by a deceleration and finally a stagnation. Abstract As secondarily aquatic carnivores, seals display several phenotypic differences compared to their terrestrial relatives.

Interrogating Mental Stasis: A Critical Examination Of Two Francophone African Novels
After 1960, there is a shift from the Negritude idea which celebrates African culture. Most African creative writers are troubled by the kind of politics and political ideologies Africans are subjected to.

Estimating in vivo midfoot and hindfoot joint locations using external skin markers
Abstract Musculoskeletal modeling offers a non‐invasive approach to analyze human movement, enabling estimation of forces that are difficult to measure experimentally. In musculoskeletal modeling, the human body is represented as rigid segments connected by joints.

Abstract The obstetrical dilemma hypothesis (ODH) proposes an evolutionary trade‐off between obstetric requirements and locomotor performance. However, whether external pelvic breadth measures influence walking energetics during human growth remains poorly understood.

The “costly son” hypothesis: Sons exacerbate obstetrical dilemmas in humans and other mammals
Abstract Human childbirth has often been considered uniquely difficult among mammals, yet recent evidence suggests that obstructed labor and fetopelvic disproportion are widespread across placental mammals. Here, we propose the “costly son” hypothesis: because male offspring are typically larger at birth, they impose greater obstetric risk on mothers ...
