The idea that humans are similar to certain great apes had been obvious to people for some time, but the idea of the biological evolution of species in general was not legitimized until after Charles Darwin published On the Origin of Species in 1859.
Ideja da su ljudi slični nekim čovjekolikim majmunima mnogo je vremena bila očita ljudima, ali ideja biološke evolucije vrsta općenito nije bila legitimirana sve dok Charles Darwin nije objavio Podrijetlo vrsta (On the Origin of Species) 1859. godine.
