The network theory of aging supports the idea that multiple connected processes contribute to the biology of aging.
Kirkwood and Kowald helped to establish the first model of this kind by connecting theories and predicting specific mechanisms.
In departure of investigating a single mechanistic cause or single molecules that lead to senescence, the network theory of aging takes a systems biology view to integrate theories in conjunction with computational models and quantitative data related to the biology of aging.
The network theory of aging provides a deeper look at the damage and repair processes at the cellular level and the ever changing balance between those processes.
To fully understand the network theory as its applied to aging you must look at the different hierarchical elements of the theory as it pertains to aging.
