Growing evidence indicates that human activities are causing cancer rates to rise in both
human and wildlife populations. This is due to the inability of ancestral anti‐cancer defences …

Genetic diversity is essential for adaptive capacities, providing organisms with the potential
of successfully responding to intrinsic and extrinsic challenges. Although a clear reciprocal …

Some cancers have evolved the ability to spread from host to host by transmission of
cancerous cells. These rare biological entities can be considered parasites with a host …

Infectious diseases, including transmissible cancers, can have a broad range of impacts on
