Introduction. Hyperplastic diseases of the female reproductive system are localized in second place after infectious diseases, and take first by severity. It is known that certain phytonutrients have a chemoprotective effect on organs system. The purpose this review to evaluate potential protective glucosinolates their derivatives isolated from cruciferous plants organs. Material methods. A sys...
absence of viviparity or at least egg-retention in birds. And what drives research if not challenging mysteries? Moreover, the borderline between inventing adaptive stories and proposing hypotheses to generate testable predictions is not sharp. The book presents new ideas at the research frontier, which is one of its many merits. For instance, CluttonBrock argues that the potential reproductive...
Molecular analyses in several taxa have consistently shown that genes involved in reproduction are rapidly evolving and subjected to positive selection. The mechanism behind this evolution is not clear, but several proposed hypotheses involve the coevolution between males and females. In Drosophila, several male reproductive proteins (Acps) involved in male-male and male-female interactions sho...
Eusociality is a distinct form of biological organization. A key characteristic of advanced eusociality is the presence of non-reproductive workers. Why evolution should produce organisms that sacrifice their own reproductive potential in order to aid others is an important question in evolutionary biology. Here, we provide a detailed analysis of the selective forces that determine the emergenc...
