Having made substantial progress understanding molecules, cells, genes and pathways,
aging biology research is now moving toward integration of these parts, attempting to …

Between the 1930s and 50s, evolutionary biologists developed a successful theory of why
organisms age, firmly rooted in population genetic principles. By the 1980s the evolution of …

Age-related change in human haematopoiesis causes reduced regenerative capacity,
cytopenias, immune dysfunction and increased risk of blood cancer,–, but the reason for …

Lifetime reproductive success of individuals in a natural population provides an estimate of
Darwinian fitness. We calculated lifetime reproductive success in a colony of female …

Birds have been comprehensively assessed on the International Union for Conservation of
Nature (IUCN) Red List more times than any other taxonomic group. However, to date …

As people live longer, ages at death are becoming more similar. This dual advance over the

Animals exhibit an extraordinary diversity of life history strategies. These realized
combinations of survival, development and reproduction are predicted to be constrained by …

In human populations, women consistently outlive men, which suggests profound biological
foundations for sex differences in survival. Quantifying whether such sex differences are also …

A systematic investigation of growth in nature and society, from tiny organisms to the
trajectories of empires and civilizations. Growth has been both an unspoken and an explicit …

Proteases are a set of enzymes that have been involved in multiple biological processes
throughout evolution. Among them, extracellular matrix (ECM) remodeling has emerged as …
