Cutting through the complexity of cell collectives
Carey D. Nadell,Vanni Bucci,Knut Drescher,Simon A. Levin,Bonnie L. Bassler,Bonnie L. Bassler,Joao B. Xavier +6 more
TL;DR: It is argued that combining mechanistic theory with theoretical ecology and evolution provides a key strategy for clarifying how cell groups form, how they change in composition over time, and how they interact with their environments.
Journal ArticleDOI
Reproductive improvement and senescence in a long-lived bird
TL;DR: It is shown that improvements with age over most of adult life and senescence at old ages are primarily due to a genuine change in the mean among surviving individuals rather than selective disappearance or selective appearance of individuals.

Accumulation of Deleterious Mutations in Endosymbionts: Muller’s Ratchet with Two Levels of Selection
Claude Rispe,Nancy A. Moran +1 more
TL;DR: Assessment of how the fate of each mutation type is affected by host population size, numbers of symbionts transmitted to progeny, selection within and between hosts, and mutation rate finds no inoculum size is optimal for minimizing deleterious evolution for both categories of gene.
Journal ArticleDOI
Expanded social fitness and Hamilton's rule for kin, kith, and kind
TL;DR: In this article, a neighbor-modulated version of Hamilton's rule for kith and kind selection is introduced, which generalizes Hamilton's insight that we can model social selection through a sum of fitness effects, each multiplied by an appropriate association coefficient.
Journal ArticleDOI
Altruism and organism: disentangling the themes of multilevel selection theory.
TL;DR: It is reasonable to expect higher‐level units to evolve into adaptive units with respect to specific traits, even when their members are not genealogically related and do not behave in ways that are obviously altruistic.
