Editing Hair (section)

==== The EDAR locus ====
A group of studies have recently shown that genetic patterns at the EDAR locus, a region of the modern human genome that contributes to hair texture variation among most individuals of East Asian descent, support the hypothesis that (East Asian) straight hair likely developed in this branch of the modern human lineage subsequent to the original expression of tightly coiled [[natural afro-hair]].<ref>{{cite journal|pmid=18065779|last1=Fujimoto|first1=A|year=2008|pages=835–43|issue=6|volume=17|last2=Kimura|first2=R|journal=Human Molecular Genetics|last3=Ohashi|first3=J|last4=Omi|first4=K|last5=Yuliwulandari|first5=R|last6=Batubara|first6=L|last7=Mustofa|first7=MS|last8=Samakkarn|first8=U|last9=Settheetham-Ishida|first9=W|last10=Ishida|first10=T.|last11=Morishita|first11=Y.|last12=Furusawa|first12=T.|last13=Nakazawa|first13=M.|last14=Ohtsuka|first14=R.|last15=Tokunaga|first15=K.|title=A scan for genetic determinants of human hair morphology: EDAR is associated with Asian hair thickness|doi=10.1093/hmg/ddm355|display-authors=8|doi-access=free}}</ref><ref>{{cite journal|pmid=18704500|last1=Fujimoto|first1=A|year=2008|pages=179–85|issue=2|volume=124|last2=Ohashi|first2=J|journal=Human Genetics|last3=Nishida|first3=N|last4=Miyagawa|first4=T|last5=Morishita|first5=Y|last6=Tsunoda|first6=T|last7=Kimura|first7=R|last8=Tokunaga|first8=K|title=A replication study confirmed the EDAR gene to be a major contributor to population differentiation regarding head hair thickness in Asia|url=http://www.tulips.tsukuba.ac.jp/dspace/bitstream/2241/103672/1/HG_124-2.pdf|doi=10.1007/s00439-008-0537-1|access-date=14 December 2010|archive-url=https://web.archive.org/web/20110205011119/http://www.tulips.tsukuba.ac.jp/dspace/bitstream/2241/103672/1/HG_124-2.pdf|archive-date=5 February 2011|url-status=dead|hdl=2241/103672|s2cid=20084816|hdl-access=free}}</ref><ref>{{cite journal|last1=Mou|first1=C|last2=Thomason|first2=HA|last3=Willan|first3=PM|last4=Clowes|first4=C|last5=Harris|first5=WE|last6=Drew|first6=CF|last7=Dixon|first7=J|last8=Dixon|first8=MJ|last9=Headon|first9=DJ|year=2008|title=Enhanced ectodysplasin-A receptor (EDAR) signaling alters multiple fiber characteristics to produce the East Asian hair form|url=https://www.pure.ed.ac.uk/ws/files/8264337/Mou_et_al_EDAR_and_Asian_Hair_2008_supplementary_material.pdf|journal=Human Mutation|volume=29|issue=12|pages=1405–11|doi=10.1002/humu.20795|pmid=18561327|hdl=20.500.11820/0b35a959-86c8-44e5-b100-20639dd6bbf1|s2cid=37696013|access-date=30 January 2019|hdl-access=free}}</ref> Specifically, the relevant findings indicate that the EDAR mutation coding for the predominant East Asian 'coarse' or thick, straight hair texture arose within the past ≈65,000 years, which is a time frame that covers from the earliest of the 'Out of Africa' migrations up to now.
