Overview
A presentation exploring the relationship between social organization and aging in ant colonies, titled 'Of Ants & Aging.' The work examines the paradox of lifespan variation across castes in social insects, where queens can live decades while workers live weeks to months. It connects ant aging biology to broader questions about the evolution of senescence and the role of social structure in shaping longevity.

Findings and contributions
- The speaker distinguishes age (clock time elapsed) from aging (a process and embodied outcome linked to species-specific phenotypes and disease/death risk), stating the definition is not normative.
- The slides note that some ant species have colonies that do not age, possibly via asexual or intra-nest sexual reproduction.
- On the utility of aging, the talk suggests one shared answer for ants and humans may be that there is no specific utility, only an order-vs-disorder tradeoff.
- At nestmate scale, the speaker proposes turnover of damaged nestmate bodies may be favorable, favoring aging processes at that scale.
Methods
- Tinbergen's four questions applied to ant and human aging — The talk organizes its question of why aging occurs around Tinbergen's 4 Questions, comparing ants (nestmate and colony scales) with humans.
- Decayed-house example illustrating four kinds of explanation — A worked example explains why a house is decayed in developmental, material, functional and deep-time terms before applying the scheme to aging.
- Insulin signaling as a focal example of aging mechanism — Mechanism discussion is restricted to insulin signaling, drawing on cited work such as Yan et al. 2022 on long-lived reproductive ant castes.
- Kin selection vs. multi-level selection distilled from a prior stream — The evolutionary account is limited to kin selection and multi-level selection, presented as a distillation of ActInf PaperStream #001.0.
