The Danaid Theory of Aging

Area of Science:

• Evolutionary biology
• Gerontology
• Developmental biology

Background:

• Classical evolutionary theories posit aging arises from insufficient selective pressure.
• These theories explain aging through genes or resource allocation but not aging pattern diversity.
• An alternative explanation is needed to account for the origin and diversity of aging.

Purpose of the Study:

• To propose a new evolutionary-mechanistic theory of aging, the Danaid theory.
• To explain the origin and diversity of aging patterns beyond classical evolutionary theories.
• To integrate advances in developmental biology, genetics, biochemistry, and complex systems theory.

Main Methods:

• Reviewing and synthesizing classical evolutionary theories of aging.
• Drawing on recent advances in developmental biology, genetics, biochemistry, and complex systems theory.
• Proposing the Danaid theory, focusing on inherent physiological restrictions and developmental constraints.

Main Results:

• Aging may stem from inherent restrictions on maintenance and repair in complex organisms, established during development.
• These developmental constraints vary systematically across taxa.
• Such variations in constraints are key to understanding diverse aging and lifespan patterns across the tree of life.

Conclusions:

• The Danaid theory offers a novel perspective on aging, emphasizing inherent biological limitations.
• Understanding the interplay of constraints, trade-offs, chance events, and selection is crucial for explaining aging diversity.
• Future research should focus on mapping these constraints across diverse taxa to understand aging variations.
