The visual worlds of most primates are rich with potential color signals, and many
representatives of the order have evolved the biological mechanisms that allow them to …

Previous research revealed significant individual variations in opsin genes and cone
photopigments in several species of platyrrhine (New World) monkeys and showed that …

Many species of platyrrhine primates are characterised by sex-linked color vision
polymorphism. This presents an opportunity to study the biology and ecology of individuals …

To better understand the evolutionary history of human decision-making, we compare
human behavior to that of two monkey species in a symmetric game of conflict with two …

Primate colour vision depends on a matrix of photoreceptors, a neuronal post receptoral
structure and a combination of genes that culminate in different sensitivity through the visual …

René Magritte is a painting entitled “La trahison des images”(The treason of images), from
1929, consisting of a brown smoking pipe suspended upon a uniform background with the …

Color‐vision polymorphism in New World monkeys occurs because of an allelic
polymorphism of the single‐copy red‐green middle‐to‐long‐wavelength‐sensitive (M/LWS) …

Here we demonstrate differences in the relative performance of 15 callitrichids tested in a
series of color visual discrimination experiments. Munsell color chips were chosen as stimuli …

Among placental mammals, only primates have trichromatic color vision, however this is not
a uniform condition. Under different genetic status, Old World monkeys have routine …

Electrophysiological and molecular genetic studies have shown that howler monkeys
(Alouatta) are unique among all studied platyrrhines: they have the potential to display …
