The package fitdistrplus provides functions for fitting univariate distributions to different types
of data (continuous censored or non-censored data and discrete data) and allowing different …

Pigmentation patterns of the visible part of the eyeball, encompassing the iris and portions of
the sclera, have been discussed to be linked to social cognition in primates. The cooperative …

External eye appearance across primate species is diverse in shape and colouration, yet we
still lack an explanation for the drivers of such diversity. Here we quantify substantial …

Convergent evolution of phenotypes is considered evidence that evolution is deterministic.
Establishing if such convergent phenotypes arose through convergent evolutionary …

While snake venoms have been the subject of intense study, comparatively little work has
been done on lizard venoms. In this study, we have examined the structural and functional …

Comparative examinations of external eye morphology in primates initially focused on
communicative functions of the eye. Subsequent work has failed to find consistent …

The white sclera is important in facilitating gaze perception in humans. Iris color may
likewise influence gaze perception but no previous studies have directly assessed its effect …

Lemurs, the living primates most distantly related to humans, demonstrate incredible
diversity in behaviour, life history patterns and adaptive traits. Although many lemur species …

Accurate species delimitation based on an integrative approach is indispensable for
biodiversity evaluation. Accordingly, species that were formerly only described …

Species vary widely in the conspicuousness of their eye morphology and this could
influence gaze perception. Eyes with conspicuous morphology can enhance gaze …
