--- abstract: |- The author has discovered a new syndrome with quadrupedal gait, flexed head and body, primitive speech, severe mental retardation, and mild cerebellar signs with a disturbed conscious experience. This syndrome was exhibited by 5 of 19 children from a consanguineous family. The pedigree demonstrated a typical autosomal-recessive inheritance. The genetic nature of this syndrome suggests a backward stage in human evolution, which is most probably caused by a genetic mutation, rendering, in turn, the transition from quadrupedality to bipedality. This would then be consistent with theories of punctuated evolution. On the other hand, the extensor motor system causing a resistance of the body against the gravity may actually be subjected to evolutionary forces. This new syndrome may be used as a live model for human evolution. altloc: - http://taylorandfrancis.com chapter: ~ commentary: ~ commref: ~ confdates: ~ conference: ~ confloc: ~ contact_email: ~ creators_id: [] creators_name: - family: Tan given: Uner honourific: Prof. Dr. lineage: '' date: 2006 date_type: published datestamp: 2006-07-01 department: ~ dir: disk0/00/00/49/41 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: - family: Weinstein given: Sidney honourific: Sir lineage: '' eprint_status: archive eprintid: 4941 fileinfo: /style/images/fileicons/application_pdf.png;/4941/1/UNERTAN_SYNDROME_(IJN).pdf full_text_status: public importid: ~ institution: ~ isbn: ~ ispublished: pub issn: ~ item_issues_comment: [] item_issues_count: 0 item_issues_description: [] item_issues_id: [] item_issues_reported_by: [] item_issues_resolved_by: [] item_issues_status: [] item_issues_timestamp: [] item_issues_type: [] keywords: 'erect posture, evolution, human, quadrupedal gait' lastmod: 2011-03-11 08:56:28 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: ~ pagerange: 361-369 pubdom: FALSE publication: International Journal of Neuroscience publisher: Taylor & Francis refereed: TRUE referencetext: |- Tan, U.
