Characteristics of hosts and parasites have a genetic basis, and thus can be shaped by
coevolution. Infections measured under laboratory conditions have shown that the environment …

Virtually all plants and animals, including humans, are home to symbiotic microorganisms.
Symbiotic interactions can be neutral, harmful or have beneficial effects on the host organism. …

It is a commonly held view that genetically homogenous host populations are more vulnerable
to infection than genetically diverse populations. The underlying idea, known as the ‘…

What are the causes of natural selection? Over 40 years ago, Van Valen proposed the Red
Queen hypothesis, which emphasized the primacy of biotic conflict over abiotic forces in …

… Tracing Achilles' appearances in the works of poets, generals, philosophers, priests, and
patriots, Katherine Callen King establishes the moral or political significance attached to the …

Animals live in symbiosis with numerous microbe species. While some can protect hosts from
infection and benefit host health, components of the microbiota or changes to the microbial …

Obesity has been associated in the literature with other pregnancy risks such as hypertension
and diabetes mellitus, but disagreement persists about the expected course and …

Microbes can defend their host against virulent infections, but direct evidence for the adaptive
origin of microbe-mediated protection is lacking. Using experimental evolution of a novel, …

Hybridization of parasites is an emerging public health concern at the interface of infectious
disease biology and evolution. Increasing economic development, human migration, global …

The maintenance of sexual reproduction in natural populations is a pressing question for
evolutionary biologists [1, 2]. Under the "Red Queen" hypothesis, coevolving parasites reduce …
