A classic study from more than 60 years ago suggesting that males are more promiscuous and females more choosy in selecting mates may, in fact, be wrong, say life scientists who are the first to repeat the historic experiment using the same methods as the original.
In early human evolution, when faithful females began to choose good providers as mates, pair-bonding replaced promiscuity, laying the foundation for the emergence of the institution of the modern family.
Discerning males remain faithful...if you are a spider.
It's all about the grandkids! That's what a team led by an Indiana University biologist has learned about promiscuous female birds and why they mate outside their social pair.
Scientists at the University of Liverpool have found that male fruitflies experience a type of 'paranoia' in the presence of another male, which doubles the length of time they mate with a female, despite the female of the species only ever mating with one male.
Inbred male sperm have been found to fertilize fewer eggs when in competition with non-inbred males according to a new study by the University of East Anglia.
Scientists have found new evidence to explain how female insects can influence the father of their offspring, even after mating with up to ten males. A team from the University of Exeter has found that female crickets are able to control the amount of sperm that they store from each mate to select the best father for their young.
Attractive males release fewer sperm per mating to maximize their chances of producing offspring across a range of females, according to a new paper on the evolution of ejaculation strategies.
A new study has revealed that mother birds can provide an early advantage to the chicks that they have sired with their non-social partner (known as extra-pair offspring).
A Scottish study challenges longstanding expectations that men are promiscuous and women tend to be more particular when it comes to choosing a mate. Lead study author Dr. Gillian R. Brown of the School of Psychology at the University of St. Andrews said that in 1948, Angus J.
