The evolution of herbivory in early tetrapods was crucial in the establishment of terrestrial ecosystems, although it is so far unclear what effect this innovation had on the macro-evolutionary patterns observed within this clade. The clades which entered this...

Mammalian tears are produced by lacrimal glands to protect eyes and to function in chemical communication and immunity. However, excess tears flow through nasolacrimal ductsto nasal tissues, and via the nasopharyngeal duct to the oral cavity where digestion starts....

Background. Interactions between eukaryotic amoebae and bacteria are understudied and important. Bacteria inside of amoebae are protected from external forces including antibiotics. An excellent model for bacteria-amoeba interactions is the social amoeba Dictyostelium...

Sexual selection favors traits that increase mating and, thus, reproductive success. Some scholars have suggested that intrasexual selection driven by contest competition has shaped human male aggression. If this is the case, one testable hypothesis is that beliefs...

The Cleveland-Lloyd Dinosaur Quarry (CLDQ) is the densest deposit of Jurassic theropod dinosaurs discovered to date. Unlike typical Jurassic bone deposits, it is dominated by the presence of Allosaurus fragilis. Since excavation began in the 1920’s numerous hypotheses...

Mutation processes differ between types of point mutation, genomic locations, cells, and biological species. For some point mutations, specific neighbouring bases are known to be mechanistically influential. Beyond these cases, numerous questions remain unresolved...

In some insects, males produce costly ejaculates that reduce the typical sexual imbalance in potential reproductive rates thus influencing the mode and intensity of sexual selection. In Lepidoptera, in particular, males tend to invest heavily in mate searching,...

The patella is a sesamoid bone located in the major extensor tendon of the knee joint, in the hindlimb of many tetrapods. Although numerous aspects of knee morphology are ancient and conserved among most tetrapods, the evolutionary occurrence of the patella is...
