Duplication of tumor suppressor genes contributed to the evolution of large, long-lived elephants.

Elephants escaped enhanced cancer susceptibility by evolving more master tumor suppressor genes.

Sloths, armadillos, and anteaters evolved genetic and cellular traits that make them remarkably cancer resistant.

The presence of humans induces behavioral modifications in many large carnivore and ungulate species, restructuring spatiotemporal relationships between African predators and their prey.

Cellularization in Sphaeroforma arctica generates a self-organized structure that morphologically resembles an epithelium, and is associated with tightly regulated expression of cell adhesion pathways.

Endogenous virus sequences in the genomes of modern mammals reveal the global spread of an ancient virus lineage, including frequent interspecies transmission, adaptation, and emergence spanning several million years of mammalian evolution

Teeth are maintained in two amphibian groups (caecilians and salamanders) but were lost in frogs over 20 times independently, a higher incidence of edentulism than any other major vertebrate group.

Cancer control, DNA repair, and immunity are key functionalities underlying the evolution of extended lifespan in mammals.

Ventrolateral periaqueductal gray neurons signal fear output through patterned inhibition of neural activity.
