Background: Consistent across cultures and throughout time is the male preference for younger females. Given its prevalence, the mate choice theory proposes that age–disparate relationships may have contributed to the evolution of maternal mortalit

Ever since the pioneering work of Darwin and Wallace, evolutionary biologists have attempted to understand the evolutionary dynamics of genetic systems. A range of theories on evolutionary ratesfrom static to gradual to punctuated to quantumhave been

The origins of sex-biased differences in disease and health are of growing interest to both medical researchers and health professionals. Several major factors have been identified that affect sex differences in incidence of diseases and mental disor

This 2004 collection of essays deals with the foundation and historical development of population biology and its relationship to population genetics and population ecology on the one hand and to the rapidly growing fields of molecular quantitative g
Mate choice, marriage, and menopause are life-altering events affecting women’s health. It has been hypothesized that mate choice through age disparity in marriage may have contributed to the evolution of menopause and the persistence of maternal m

Sexual dimorphism or sex bias in diseases and mental disorders have two biological causes: sexual selection and sex hormones. We review the role of sexual selection theory and bring together decades of molecular studies on the variation and evolution
Menopause is an unusual fertility reducing trait and it goes against natural selection. Group selection-based theories, such as the Grandmother hypothesis can, in principle, explain the evolution of menopause, but they do not explain how a fertility

Vertically aligned and highly dense Zinc oxide (ZnO) nanorods (NRs) have been successfully synthesized by a two-step hydrothermal method and decorated by silver (Ag) nanoparticles (NPs) via a dip coating technique. Absorption spectra indicate the pre

The mating success of larger male Drosophila melanogaster in the laboratory and the wild has been traditionally been explained by female choice, even though the reasons are generally hard to reconcile. Female choice can explain this success by virtue

The high hopes for the Human Genome Project and personalized medicine were not met because the relationship between genotypes and phenotypes turned out to be more complex than expected. In a previous study we laid the foundation of a theory of comple
