As had been demonstrated by responses to the publication of Vestiges of the Natural History of Creation in 1844, the most controversial aspect of evolutionary biology is the implication of human evolution that humans share common ancestry with apes and that the mental and moral faculties of humanity have the same types of natural causes as other inherited traits in animals.
Como xa se demostrara polas respostas á publicación do libro Vestiges of the Natural History of Creation (Vestixios da Historia Natural da Creación) en 1844, os aspectos máis controvertidos da bioloxía evolutiva son que a evolución humana implica que os humanos comparten un antepasado común cos simios e que as facultades mentais e morais da humanidade teñen o mesmo tipo de causas naturais que outros trazos herdados nos animais.
