if evolution had begun from a different starting point within the network of sequences encoding the ancestral function, outcomes with different genetic and biochemical forms would probably have resulted. illuminate the topology of the vast space of possibilities from which history sampled one path, highlighting how the outcome of evolution depends on a serial chain of compounding chance events.

我々が生きている生物学的な現実世界は進化のサイコロが何度も振られた中で出た1つの帰結にすぎない。そして、今この現在があることにはおそらく特段の理由はない。
