Both sexual selection and natural selection can influence the form of dimorphism in
secondary sexual traits. Here, we used a comparative approach to examine the relative …

Sexual size dimorphism shows a remarkably widespread relationship to body size in the
animal kingdom: within lineages, it decreases with size when females are the larger sex, but …

Grooming repertoires are exhibited by all terrestrial mammals, and removal of ectoparasites
is an important ancestral and current function. Parasite-defence grooming is regulated both …

In many animal groups, sexual size dimorphism tends to be more pronounced in species
with large body size. Similarly, in a previous cross-cultural analysis, male and female stature …

Sexual selection theory has provided a successful framework for studying sex differences in
behaviour, morphology, development and reproductive strategies, as well as the resulting …

Sexual selection is commonly envisaged as a force working in opposition to natural
selection, because extravagant or exaggerated traits could apparently have never evolved …

Sexual selection in the form of sperm competition is a major explanation for small size of
male gametes. Can sexual selection in polyandrous species with reversed sex roles also …

Rensch's rule, positive scaling of sexual size dimorphism (SSD) with body size, has been
shown to be present in the evolutionary history of Primates. However, in some radiations …

In strepsirrhine primates, the accessory olfactory system plays an important role in
intrasexual competition. However, it does not play the same role in most haplorhines. In …

Recent discoveries of early anthropoid primate fossils from Africa and Asia have generated
a tremendous amount of new information about the origins of modern anthropoid primates …
