Research conducted in the last fifteen years has placed in question many of the traditional
conclusions scholars have formed about human female sexuality. Though conventional …

The investigation of prosocial behavior is of particular interest from an evolutionary
perspective. Comparisons of prosociality across non-human animal species have, however …

Food sharing in birds occurs largely in the context of parental care and courtship. Previous
studies found that juvenile jackdaws demonstrate high levels of active giving outside these …

Food sharing is common in birds between mated pairs during courtship and by helpers at
the nest in cooperatively breeding species. In contrast to primates, however, food sharing …

A striking but unexplained pattern in biology is the promiscuous mating behaviour in socially
monogamous species. Although females commonly solicit extra-pair copulations, the …

Extra-pair copulation (EPC) occurred in most socially monogamous bird species. The
mechanisms leading to the frequent occurrence of extra-pair offspring (EPO, EPY) in socially …

Most songbirds are socially monogamous, yet molecular studies have found that in most
species, some offspring in the nest are sired by males other than the social mate of the …
