As previously established in Body Intelligence, body intelligence is not compatible with aging elimination (in Homo sapiens, for spectacular results have been achieved in the so-called negligibly senescent organisms such as T. dohrnii). The repair capabilities of the human body are simply too limited. This limitation may be considered in an evolutionary context. From this perspective, an indefinite life span for Homo sapiens may be construed as unfavorable to the evolvability of the species or the result of “evolutionary negligence”, pleiotropic effects or energy tradeoffs as expressed by the seminal theories of Medawar, Williams (antagonistic pleiotropy) and Kirkwood (disposable soma theory), respectively. However, though the curtailing of longevity (on the premise of its deleterious effect on evolvability) may have been exigent in evolutionary prehistory, it may no longer be functional. Present day life spans for Homo sapiens may simply represent a vestige of an ancient requirement – merely a single solution to the evolutionary problem of the propagation of the species. It is not untenable that there are other viable solutions that translate to protracted life spans but that these solutions are “kinetically” separated from the present solution and require an “activation energy” (which may be provided by life extension). Alternatively, it may be argued that the evolutionary procedure has found a satisfactory solution to the problem of gene propagation and evolvability and consequently has no incentive for “finding” another strategy which may be just as good (or better).
Whatever the obstacles standing in the way of the life extension, it is indisputable that we need to go beyond body intelligence. This necessitates the use of external agents (information vectors) such as molecular repair nanotechnology. Molecular repair nanotechnology may ultimately form the basis of the transformation of human biochemistry via their seamless integration into the human physiology (a prospect most likely to be realized through synthetic biology, genetic engineering and nanomedicine).
