Predictions and Tests

A starting list of testable implications from DESTA and EOS.

DESTA predictions

PredictionImplication
Sexual selection maintains senescence.Mate-choice systems should use age-related physiological cues, and disruption of those cues should alter mating outcomes.
Natural selection tunes the rate of senescence.Species and populations under different ecological pressures should show corresponding differences in senescence rates.
Intrinsic growth terminators should differ from extrinsic growth slowers.Species able to continue fitness-increasing growth should show altered or reduced senescence patterns compared with intrinsically growth-terminated species.
Senescence is centrally regulated.Age-related changes should show coordinated hypothalamic, endocrine, circadian, immune, autonomic, and metabolic patterns rather than appearing only as independent cellular failures.
Senescence structures predation.In wild populations, predation should be disproportionately directed toward older or physiologically senescent individuals where predators can detect vulnerability.

EOS predictions

PredictionImplication
Selection mechanisms evolve.Regulatory, immune, neural, and cognitive systems that bias survival or reproduction should themselves vary, impose costs, and evolve under selection.
Selection modes layer rather than replace one another.Physical, algorithmic, and cognitive selection should operate simultaneously in complex organisms.
