--- abstract: |- A new family exhibiting “Unertan Sydnrome” was discovered. The pedigree analysis showed marriages between relatives. This family was similar to the first one (see Tan, 2006a), providing a firm evidence for the new syndrome. The affected children showed habitual quadrupedal walking gait, that is, they walked on wrists and feet with straight legs and arms. Their heads and bodies were mildly flexed; they exhibited mild cerebellar signs, and severe mental retardation. The pedigree demonstrated a typical autosomal-recessive inheritance. The genetic nature of this syndrome suggests a backward stage in human evolution (devolution), which would be consistent with theories of punctuated evolution. The results reflected a new theory on the evolution of human beings. That is, the evolution of humans would in fact be the evolution of the extensor motor system, responsible for upright posture, against the gravitational forces. This would be coupled with the emergence of the human mind, which can be considered a reflexion of the human motor system, in accord with the psychomotor theory (see Tan, 2005a). The most important characteristic of the newly emerged human mind was the resistance against gravitational forces. This was the resistive mind, the origins of human creativity. altloc: - http://www.taylorandfrancis.com chapter: ~ commentary: ~ commref: ~ confdates: ~ conference: ~ confloc: ~ contact_email: ~ creators_id: [] creators_name: - family: Tan given: Uner honourific: Prof. Dr. lineage: '' date: 2006-07 date_type: published datestamp: 2006-07-23 department: ~ dir: disk0/00/00/50/11 edit_lock_since: ~ edit_lock_until: ~ edit_lock_user: ~ editors_id: [] editors_name: - family: Weinstein given: Sidney honourific: Prof. Sir lineage: '' - family: Hyden given: Holger V. honourific: Prof. lineage: '' - family: Renzi given: Emino de honourific: Prof. lineage: '' - family: Tan given: Uner honourific: Prof. lineage: '' eprint_status: archive eprintid: 5011 fileinfo: '/style/images/fileicons/application_pdf.png;/5011/1/EVIDENCE_FOR_UNERTAN__IJN_[1].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: |- bipedality, evolution, human, mental retardation, mind, quadrupedality, Unertan syndrome lastmod: 2011-03-11 08:56:32 latitude: ~ longitude: ~ metadata_visibility: show note: ~ number: 7 pagerange: 763-774 pubdom: FALSE publication: International Journal of Neuroscience publisher: Taylor & Francis refereed: FALSE referencetext: |- Elena, S.
