With The Origin of Higher Taxa, Tom Kemp sifts through the layers of paleobiological, genetic, and ecological evidence on a quest to answer this essential, game-changing question of biology. Looking beyond the microevolutionary force of Darwinian natural selection, Kemp enters the realm of macroevolution, or evolution above the species level.Bilateral (zooloxía) Os bilaterais ( Bilateria) son os animais con simetría bilateral, na cal o organismo é simétrico respecto a un plano ( plano saxital) que divide o corpo en dúas metades idénticas en espello.
