Achrati Ahmed, Neoteny, female hominin and cognitive evolution, in Rock Art Research, vol. 31, n. 1, Novembre 2014, p. 232–238.
«In humans, neoteny is manifested in the resemblance of many physiological features of a human to a late-stage foetal chimpanzee. These foetal characteristics include hair on the head, a globular skull, ear shape, vertical plane face, absence of penal bone (baculum) in foetal male chimpanzees, the vagina pointing forward in foetal ape, the presence of hymen in neonate ape, and the structure of the foot. ‘These and many other features’, Bednarik says, ‘define the anatomical relationship between ape and man as the latter’s neoteny’»
