Once an influenza infection is established, selection acts efficiently in favouring fitter viral genotypes, its effects being limited only by the short length of a typical infection.

The wtf meiotic drivers change the fitness landscape of meiosis in outcrossed Schizosaccharomyces pombe demonstrating that genetic parasites can favor the evolution of variants that disrupt meiotic fidelity.

A common rice pest can avoid its natural parasite by settling on plants that smell like they have been damaged by a species of caterpillar.

The brown planthopper has evolved a highly adaptive oviposition strategy by exploiting caterpillar-induced plant volatiles that provide safe havens for its offspring.

Natural light gradients within a habitat may have helped form new fly species that have differing preferences for light.

Phototaxis and courtship behavioral preferences reflect strong correlation with differences in olfactory and visual nervous system investment across five monophyletic Drosophila species, and could help explain their speciation events.

A seminal protein from a mating-male can bind sperm previously stored in his mate, providing direct benefits to the sperm from the prior male that mated with her.

In an in vitro RNA replication system, an RNA spontaneously diversifies and continuously evolves through coevolution with parasitic entities.

The incus of the middle ear plays a role in supporting the lower jaw prior to the formation of the mammalian jaw joint allowing early feeding in monotremes and marsupials.

Four species of seabird produce efficient propulsive wakes while flying in the air and while swimming underwater suggesting that selection has optimized these species for locomotion in remarkably different fluids.
