The Vital Question
Lane connects life's origins and the emergence of complex cells with the energy arrangements that make biological organisation possible.
Energy is central to explaining living organisation.
A living system needs more than instructions; it needs a workable supply and organisation of energy. Lane makes that practical constraint central to questions about how complex life became possible.
Cells depend on gradients and controlled exchanges.
Lane examines proposed settings for life's early emergence.
The transition to complex cells presents a separate explanatory problem.
Mitochondria change the energy available within that organisation.
A promising explanation can remain incomplete. The hypotheses connect evidence across fields, but origin stories deserve particular care because plausible reconstruction is not the same as directly observing the past.
Endosymbiosis connects cellular complexity with an inherited partnership.
Genetic arrangements interact with energetic constraints.
Later consequences involve reproduction, development, and ageing.
Origin scenarios and some wider hypotheses remain debated.
The central thesis makes energy part of the explanation, not background supply alone.
