Each cell division comes with the risk of mutations that could eventually lead to cancer. How do organisms attain their mature sizes without succumbing to cancer? What happens when large-bodied lineages shrink in size? Can cancer risk constrain body size evolution?

Iteroparous animals often express dramatic variation in life-history traits over the course of a lifetime.

Metascience, or metaresearch, is a field of research that has grown out of the replication crisis. Amongst other things, metascience evaluates and monitors open science initiatives and other interventions to improve scientific practices and cultures.
