RARER DIRECTIONAL EVOLUTION. “Previous analyses of evolutionary patterns, or modes, in fossil lineages have focused overwhelmingly on three simple models: stasis, random walks, and directional evolution. Our expanded survey is consistent with its predecessors in finding that stasis and random walk modes are prevalent in paleontological sequences, and in suggesting that sustained directional evolution is infrequently observed.”
