A complete understanding of the feeding structures is fundamental in order to study how animals survive. Some birds use long and protrusible tongues as the main tool to collect their central caloric source (e.g. woodpeckers and nectarivores). Hummingbirds are the...

Synapsida, the clade including therapsids and thus also mammals, is one of the two major branches of amniotes. Organismal design, with modularity as a concept, offers insights into the evolution of therapsids, a group that experienced profound anatomical transformations...

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...

We comment on the recent developments and problems of three-dimensional printing in cardiology. Since there are currently no standards or consensuses for 3D printing in clinical medicine and the technology is at its infancy in cardiology, it’s very important to...

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...

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...
