Primates are the most visually adapted order of mammals. There is a rich history within
anthropology of proposed explanations for the adaptive significance of binocular vision …

Primates are distinguished by frontally directed, highly convergent orbits, which are
associated with stereoscopic vision. Although stereoscopic vision requires specialized …

Primates are characterized by forward-facing, or convergent, orbits and associated binocular
field overlap. Hypotheses explaining the adaptive significance of these traits often relate to …

Most animals have at least some binocular overlap, ie, a region of space that is viewed by
both eyes. This reduces the overall visual field and raises the problem of combining two …

Strepsirrhine and haplorhine primates exhibit highly derived features of the visual system
that distinguish them from most other mammals. Comparative data link the evolution of these …

The orbital apertures of Primates are among the most convergent (ie, facing in the same
direction) among mammals. It is often assumed that orbit convergence is associated with …

Stereopsis has been one of the most popular fields of vision research for well over a century
and is routinely measured in clinical practice, yet its functional significance has been largely …

The primate visual system has a uniquely high proportion of ipsilateral retinal projections,
retinal ganglial cells that do not cross the midline in the optic chiasm. The general …

The investigation of the visual system forms a major part of the effort to compose a more
comprehensive picture of the evolution of brain and behavior in vertebrates. The major thrust …

A primate's visual impression of the world is shaped by highly refined cortical mechanisms
for registering and interpreting images cast on the retinas. The act of seeing is normally so …
