1. Origins of Bipedalism
ABSTRACT 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 ii) why did hominins become increasingly bipedal over the time and replaced their less bipedal ancestors? To answer these questions

2. The use of pelvic fins for benthic locomotion during foraging behavior in Potamotrygon motoro (Chondrichthyes: Potamotrygonidae)
Synchronized bipedal movements of the pelvic fins provide propulsion (punting) during displacement on the substrate in batoids with benthic locomotion. In skates (Rajidae) this mechanism is mainly generated by the crural cartilages. Although lacking these anatomical structures, some stingray species show modifications of their pelvic fins to aid in benthic l

3. Calculation of weight from step impacts, using a piezoelectric sensor / Determinação da força peso, a partir dos impactos de pisadas, utilizando um sensor piezoeletrico
Este trabalho está relacionado com o problema da pesagem de um bovino criado em campo aberto, não confinado, destinado ao corte. O conhecimento da evolução contínua do peso do animal é de grande importância neste ramo de negócios e uma solução tecnicamente satisfatória, de custo aceitável e de tecnologia proprietária, certamente representa uma s

4. Comparative kinematic analysis of bipedal and quadrupedal locomotion: a cyclographic technique.
This paper shows the convention for, and applicability of, a new computer-aided cyclographic technique for kinematic analysis of locomotion in quadrupeds. Comparison is made of the walking, trotting and galloping patterns of a reference quadruped, Canis familiaris. The method is effective where an investigator required an accurate evaluation of limb movement

5. Ontogeny of bipedal locomotion: walking and running in the chick.
1. The purpose of this study was to determine whether the production of an energy-efficient bipedal walk is an innate attribute of a precocial bird. 2. The locomotor characteristics of hatchling chicks were quantified using kinetic (ground reaction forces) and kinematic (stride length, leg support duration) measurements as the animals moved overground unrest

6. Development of the fetal ilium – challenging concepts of bipedality
Macroradiographs of 30 human fetal and neonatal ilia were analysed to investigate the early pattern of trabecular bone organization prior to the influences of direct weight-bearing locomotion. Consistent and well-defined patterns of internal organization were identified within the fetal and neonatal ilium, which correspond with previously recognized regions

7. Motions of the running horse and cheetah revisited: fundamental mechanics of the transverse and rotary gallop
Mammals use two distinct gallops referred to as the transverse (where landing and take-off are contralateral) and rotary (where landing and take-off are ipsilateral). These two gallops are used by a variety of mammals, but the transverse gallop is epitomized by the horse and the rotary gallop by the cheetah. In this paper, we argue that the fundamental diffe
