Insect heritable symbionts have proven to be ubiquitous, based on molecular screening of
various insect lineages. Recently, molecular and experimental approaches have yielded an …

In the Origin of Species, Darwin struggled with how continuous changes within a species
lead to the emergence of discrete species. Molecular analyses have since identified nuclear …

Recent decades have witnessed an explosion of theoretical and empirical studies of sex
allocation, transforming how we understand the allocation of resources to male and female …

Genomes are vulnerable to selfish genetic elements (SGEs), which enhance their own
transmission relative to the rest of an individual's genome but are neutral or harmful to the …

Throughout the natural world, organisms have responded to predators, inadequate
