For many years, it has been variously suggested that the evolution of monogamy in primates was due to paternal care, dispersed female ranging, or infanticide. It was therefore of little surprise to us that we should find that these traits are strongly associated with mating systems in primates (1). The crucial question, however, is whether these traits are potential drivers of, or secondary res...

Humans are fascinated by animal monogamy. In the 1960s, Konrad Lorenz idealized the lifelong pair-bonds of geese until one of his students pointed out some infidelities and suggested that geese may be “only human” (1), and Desmond Morris (2) speculated about the advantages of the pair-bond for early humans. Even though many theories have since been proposed, human monogamous inclinations have a...

Monogamy inequalities for the way bipartite Einstein-Podolsky-Rosen (EPR) steering can be distributed among N systems are derived. One set of inequalities is based on witnesses with two measurement settings, and may be used to demonstrate correlation of outcomes between two parties, that cannot be shared with more parties. It is shown that the monogamy for steering is directional. Two parties c...

Understanding the evolution of mating systems, a central topic in evolutionary biology for more than 50 years, requires examining the genetic consequences of mating and the relationships between social systems and mating systems. Among pair-living mammals, where genetic monogamy is extremely rare, the extent of extra-group paternity rates has been associated with male participation in infant ca...

Unlike bones, behavior does not fossilize, so it is hard to infer the evolutionary history of social traits. However, we have shown elsewhere that Bayesian phylogenetic methods allow the investigation of ancestral states and models of evolution of social grouping behaviour in primates. Here, we extend this analysis to another significant aspect of primate social life, which may be subject to di...

18 Inclusive-fitness theory highlights monogamy as a key driver of altruistic sib-rearing. Accordingly, 19 monogamy should promote the evolution of worker sterility in social insects when sterile workers 20 make for better helpers. However, a recent population-genetics analysis (Olejarz et al. 2015) found 21 no clear effect of monogamy on worker sterility. Here, we revisit this analysis. First,...

Many social Hymenoptera species have morphologically sterile worker castes. It is proposed that the evolutionary routes to this obligate sterility must pass through a 'monogamy window', because inclusive fitness favours individuals retaining their reproductive totipotency unless they can rear full siblings. Simulated evolution of sterility, however, finds that 'point of view' is critically impo...

Much attention has focused on distinguishing between social and genetic monogamy in avian taxa. However, surprisingly few studies have directly investigated this distinction among mammals. We investigated the genetic mating system of the prairie vole,Microtus ochrogaster, a popular model for mammalian monogamy and human attachment. We used space use patterns to define paired and single animals ...

Monogamy and polygamy relations characterize the distributions of entanglement in multipartite systems. We investigate monogamy with respect to any partitions for a superposition generalized $W$-class state vacuum terms Tsallis-$q$ R\'enyi-$\alpha$ entanglement. By using Hamming weight binary vectors related subsystems, new classes inequalities are derived, which shown be tighter than existing ...

Unlike classical correlation, quantum entanglement cannot be freely shared among many parties. This restricted shareability of multi-party systems is known as monogamy entanglement, which one the most fundamental properties entanglement. Here, we summarize recent theoretical progress in field We firstly review standard CKW-type inequalities terms various measures. In particular, squashed and on...
