“…Under Darwinian diseases, Rapoport (1988) first considered Alzheimer's disease as a "phylogenic regression" under the main heading "phylogenic diseases," "that compares brain aging involution to the reversed phenomenon of Darwinian evolution" (Ghika, 2008). Similarly, many neurodegenerative diseases such as Parkinson's disease (Vernier et al, 2004), gait disorders (Tan, 2005d;Tan, 2006a, b;Tan, 2010a), schizophrenia (Brüne, 2004;Burns, J.K. (2004), and the highest level gait disorders including Uner Tan syndrome, with its simianlike gait and posture or apraxia, i.e., the re-emergence of old automatism of pre-human gait, may also be considered under these phylogenic diseases (Ghika, 2008).…”
