Through Time and Across Traits: Evaluating Explanations of Human Evolution

open access: yesEvolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 3, September 2026.
ABSTRACT We argue that current explanatory practice misses two situations that can arise in any lineage, not only ours. The first is dynamic: traits continue changing in one direction when a lineage's own niche construction keeps enlarging the problem it faces.

The arboreal origins of human bipedalism

open access: yes, 2014
Almost a century and a half ago, Charles Darwin in The Descent of Man (1871: 141) highlighted the evolution of bipedalism as one of the key features of the human lineage, freeing the hands for carrying and for using and making tools. But how did it arise?

Effect of Stump Length on Postural Steadiness During Quiet Stance in Unilateral Trans-Tibial Amputee [PDF]

open access: yesAl Ameen Journal of Medical Sciences, 2010
Although force platform based Center of pressure (COP) measures of postural steadiness have been used to test the diagnostic significance of various cerebellar and labyrinthine lesions, but very few literature are available on amputees.

Narrative Review on Therapies That Influence Inflammatory Responses During Extremely Premature Perinatal Respiratory Transition

open access: yesActa Paediatrica, Volume 115, Issue 9, Page 1847-1860, September 2026.
ABSTRACT Aims and Methods Advances in neonatal care have extended borderline survival to 22–24 post‐conceptional weeks. Present review discusses approaches for prolonging short pregnancies and prevention of serious morbidities in extremely premature infants born before 28 weeks of pregnancy.

Origins of Bipedalism

open access: yes, 2017
This article aimed to review various theories of bipedalism and provide a holistic answer to human evolution. There have been two questions regarding bipedalism: i) why were the earliest hominins partially bipedal?, and i i) why did hominins become ...

Uner Tan syndrome;Tan's theory for evolution of human bipedalism

open access: yes, 2014
  Uner Tan syndrome in Kars family (Turkey) was presented, with (UTS Type-II) and without infantile hypotonia (UTS Type-I), One case exhibited early-onset quadrupedal locomotion and late-onset bipedal locomotion.

First Detailed Anatomical Study of Bonobos Reveals Intra-Specific Variations and Exposes Just-So Stories of Human Evolution, Bipedalism, and Tool Use

open access: yesFrontiers in Ecology and Evolution, 2018
Just-so stories are prominent in human evolution literature because of our tendency to create simple progressionist narratives about our “special” place in nature, despite the fact that these stories are almost exclusively based on hard tissue data.

Frequency of arboreality is correlated with longer hand skeletons in Gorilla: Analysis of a new skeletal sample of Bwindi mountain gorillas

open access: yesJournal of Anatomy, Volume 249, Issue 3, Page 544-564, September 2026.
Variation in arboreality across gorilla populations is associated with systematic differences in manual digital lengths. Using a new dataset of linear metrics from the Bwindi mountain gorillas, we quantify metacarpal and phalangeal lengths in eastern and western gorilla populations across all five rays. Consistent with quantified behavioral differences,

Evolution of Hominin Forelimbs in the Context of Bipedalism

open access: yes, 2019
The evolution of bipedalism in the hominin lineage coincided with a major shift in the locomotion function of the forelimbs, from producing external forces in contact with the substrate in the arboreal and quadrupedal last common ancestor with ...

The evolution of hominin bipedalism in two steps. [PDF]

open access: yesNature
Bipedalism is a human-defining trait1,2,3. It is made possible by the familiar, bowl-shaped pelvis, whose short, wide iliac blades curve along the sides of the body to stabilize walking and support internal organs and a large-brained, broad-shouldered ...
