In many animals, mate choice is important for the maintenance of reproductive isolation between species. Traits important for mate choice and behavioral isolation are predicted to be under strong stabilizing selection within...

Effect of partnership status on preferences for facial self-resemblance

Jitka Lindová, Anthony C. Little, Jan Havlícek, S. Craig Roberts, Anna Rubešová, Jaroslav Flegr

Jun 14, 2016

Self-resemblance has been found to have a context-dependent effect when expressing preferences for faces. Whereas dissimilarity preference during mate choice in animals is often explained as an evolutionary adaptation to...

Antagonistic coevolution between hosts and sexually transmitted infections

Ben Ashby

Jan 06, 2020

Sexually transmitted infections (STIs) are predicted to play an important role in the evolution of host mating strategies, and vice versa, yet our understanding of host-STI coevolution is limited. Previous theoretical work...

Colour pattern is the main trait that drives mate recognition between Heliconius species that are phylogenetically close. However, when this cue is compromised such as in cases of mimetic, sympatric and closely related species...

Assortative mating and digit ratio (2D:4D)

Gareth Richards, Simon Baron-Cohen, Tommy van Steen, John Galvin

Oct 08, 2020

BACKGROUND: It has been hypothesised that the ratio of length between the second and fourth fingers (2D:4D), commonly employed as an indicator of foetal sex hormone exposure, may be positively correlated between heterosexual...
