Automatic summary · not editorially reviewedA peer-reviewed review surveyed genetic, molecular and stress-related components of lifespan variation in species living at least twice as long as humans, finding shared mechanisms such as DNA maintenance, stemness and stress management, while cautioning that available data remain limited. [1]
Of 101 multicellular species with a maximum lifespan of 250 or more years, 11 are animals and 90 are plants. [1]
Both within-species and between-species lifespan variation involve mechanisms related to DNA maintenance, stemness and stress management. [1]
The authors caution that robust conclusions are limited by the lack of in-depth molecular studies and methodological variation across published studies. [1]
Survey of 101 species living 250+ years
The review by Kapsetaki and Tavernarakis, published in Aging, focuses on species living twice as long as humans or more. Of 101 multicellular species with a maximum lifespan of 250 or more years, 11 are animals and 90 are plants. The authors surveyed genetic, transcriptional, proteomic, metabolomic, regeneration-, stress- and cancer-related components of lifespan variation within and between these species. [1]
Shared DNA, stemness and stress mechanisms
The authors examined whether mechanisms regulating lifespan variation within species are the same as or different from those regulating variation between species. They identified several similarities: both types of variation involve mechanisms related to DNA maintenance, stemness and stress management. Such mechanisms are also typical of early developmental stages and germ cells. [1]
Caution due to limited molecular data
The authors caution against drawing robust conclusions from the available data. They cite the lack of in-depth molecular studies on healthspan and lifespan across thousands of individuals and species, methodological variation across published studies, and only partial understanding of how physiology and environment interact across species.

Context & limits
This explainer is based only on the video description, which summarizes a review abstract; the video and transcript were not reviewed. The description reports no primary experiments, sample sizes or follow-up, and the authors themselves note limited in-depth molecular data and methodological variation across studies.
