PUNCTUATED STASIS. “The fossil record shows that long periods of stasis are often punctuated by bursts of rapid evolution, presumably due to shifts in selective conditions and dramatic evolutionary responses. Over the history of life, multicellularity has evolved repeatedly in unrelated phylogenetic groups. The potential for the evolution of multicellularity may be less constrained than is frequently postulated.”
