This form of selection is known to be capable of maintaining genetic and fitness variation in nature, the extent of which is sensitive to the underlying genetics. We present a one-locus model of a haploid maternal effect that has sexually antagonistic consequences for of...
متن کاملSexual conflict over parental care promotes the evolution of sex differences in care and the ability to care.

By contrast, we here show that the coevolution of care and the ability to care can result in strong asymmetries in both the ability to care and...

Care is complex but recent advances are helping to unravel this complexity. The factors that promote the evolutionary origins of care and those promoting the subsequent evolution, diversification and maintenance of care are not the same. Theoretical and empirical research suggest that the origin of parental care will depend primarily on offspring survival in the absence of care, as long as ther...
