摘要

Traditionally 演化 is seen as a process where from a pool of possible variations of a 族群 (e.g. 生物 物種 or industrial goods) a few variations get selected which survive and proliferate, whereas the others vanish. Survival probabilities and proliferation rates are typically associated with the 'fitness' of particular variations. In this paper we argue that the notion of fitness is an a posteriori concept, in the sense that one can assign higher fitness to 物種 that survive but one can generally not derive or predict fitness per se. Proliferation rates can be measured, whereas 適應度景觀s, i.e. the interdependence of proliferation rates, cannot. For this reason we think that in a physical theory of 演化 such notions Should be avoided. In this spirit, here we propose a random matrix model of 演化 where selec
