Social familiarity affects Comparative phylogenetic analyses uncover the ancient roots of Indo European folktales
(2016)
Ancient population expansions and dispersals often leave enduring signatures in the cultural traditions of their descendants, as well as in their genes and languages. The international folktale record has long been regarded ...
Kinship as a frequency dependent strategy
(2016)
Humans divide themselves up into separate cultures, which is a unique and ubiquitous characteristic of our species. Kinship norms are one of the defining features of such societies. Here we show how norms of marital residence ...
Sex ratio effects on reproductive strategies in humans
(2015)
Characterizations of coy females and ardent males are rooted in models of sexual selection that are increasingly outdated. Evolutionary feedbacks can strongly influence the sex roles and subsequent patterns of sex ...
A spectacular new species of seadragon
(2015)
The exploration of Earth’s biodiversity is an exciting and ongoing endeavour. Here, we report a new species of seadragon from Western Australia with substantial morphological and genetic differences to the only two other ...
Initiation and spread of escape waves within animal groups
(2015)
The exceptional reactivity of animal collectives to predatory attacks is thought to be owing to rapid, but local, transfer of information between group members. These groups turn together in unison and produce escape waves. ...
A pheromone outweighs temperature in influencing migration of sea lamprey
(2015)
Organisms continuously acquire and process information from surrounding cues. While some cues complement one another in delivering more reliable information, others may provide conflicting information. How organisms extract ...
Pre-zygotic isolation in the macroalgal genusFucus from four contact zones spanning 100–10 000 years
(2015)
Hybrid zones provide an ideal natural experiment to study the selective forces driving evolution of reproductive barriers and speciation. If hybrid offspring are less fit than the parental species, pre-zygotic isolating ...
Crypsis via leg clustering
(2015)
The role of background matching in camouflage has been extensively studied. However, contour modification has received far less attention, especially in twig-mimicking species. Here, we studied this deceptive strategy by ...
First evidence of hybridization between golden jackal (Canis aureus) and domestic dog (Canis familiaris) as revealed by genetic markers
(2015)
Interspecific hybridization is relatively frequent in nature and numerous cases of hybridization between wild canids and domestic dogs have been recorded. However, hybrids between golden jackals (Canis aureus) and other ...
Unnoticed in the tropics
(2015)
Ricinulei are among the most obscure and cryptic arachnid orders, constituting a micro-diverse group with extreme endemism. The 76 extant species described to date are grouped in three genera:Ricinoides, from tropical ...
