The patella is a sesamoid bone located in the major extensor tendon of the knee joint, in the hindlimb of many tetrapods. Although numerous aspects of knee morphology are ancient and conserved among most tetrapods, the evolutionary occurrence of the patella is...

Structure informs function, and this may be the evolutionary reason why alternative splicing, which is capable of generating different variants of the same protein, arise. But, given the energetic cost of generating different splice variants for testing their capability...

Whilst most anthropometrical research within sport has focussed on muscle and fat distribution, more studies are measuring the relationship between stature and wingspan, which has been found to be selective criteria in many sports. In this study the stature, wingspan...

Walking velocity is an important control variable in gait disorders due to sensory or cerebellar disfunction. Non-preferred walking speeds are closely linked to a higher risk of falls. A compensation strategy of patients to avoid these speed sectors can be assumed....

Here we present a single working model that attempts at reconciliation of biological systems. To do this we recognize and emphasize a universal theme of all biological systems: a need for resources. That is, we consider the dynamics of resource allocation as a...

The ostrich is a highly cursorial bipedal land animal with a permanently elevated metatarsophalangeal joint supported by only two toes. Although locomotor kinematics in walking and running ostriches have been examined, these studies have been largely limited to...

It is shown that the mass, metabolism and length explanation (MMLE) can simultaneously compute an animal’s body mass and BMR given its characteristic length using data for humans. MMLE was advanced in 1984 to explain the relationship between metabolic rate and...

How high do we jump on the Moon? Should we build architecture with steps or should we support climbing? The hypogravity will lead to vestibular system malfunction, loss of muscular mass, and stiffness of the legs, negatively affecting a person’s balance: Yes, we...

Background. Although the trot is described as a diagonal gait, contacts of the diagonal pairs of hooves are not usually perfectly synchronized. Although subtle, the timing dissociation between contacts of each diagonal pair could have consequences on gait dynamics...

The evolution of the modern human (Homo sapiens) cranium is characterized by a reduction in the size of the feeding system, including reductions in the size of the facial skeleton, postcanine teeth, and the muscles involved in biting and chewing. The conventional...

Bone research has been re-directed in the 1990s by three revolutions: firstly the recognition that bones respond to changes in their mechanical environment in a dose-dependent way; secondly by the idea that these changes in bone size can be understood as self-adaptation...
