'''체다인'''(Cheddar Man)은 [[잉글랜드]] [[서머셋]] [[체다협곡]]에서 발견된 인간 남성의 [[화석]]이다. [[기원전 제9천년기]] [[중석기 시대]]에 살았으며, 타살당한 것으로 보인다. 또한 오른눈 [[안와]] 위에 커다란 [[병변]]이 있는 것으로 보아 죽기 전에 뼈에 감염증을 앓았던 것으로 보인다.

체다인 화석은 1903년 발굴되었으며, [[브리튼섬]]에서 발견된 완전한 인간 골격 화석으로서 가장 오래된 것이다. [[런던 자연사박물관]]에서 소장하고 있다.<ref>{{인용|title=Human Evolution |publisher=Natural History Museum |website=www.nhm.ac.uk |url=http://www.nhm.ac.uk/visit/galleries-and-museum-map/human-evolution.html |access-date=17 November 2017}}</ref><ref>{{웹 인용|title=Cheddar Man: Mesolithic Britain's blue-eyed boy |url=https://www.nhm.ac.uk/discover/cheddar-man-mesolithic-britain-blue-eyed-boy.html |access-date=2023-01-01 |website=www.nhm.ac.uk |language=en}}</ref>

[[세포핵 DNA]] 분석 결과, 체다인은 전형적인 [[서유럽 수렵채집민]]으로 밝혀졌다. [[홍채]]가 녹색 또는 파란색이었고, 머리카락은 어두운 색에, 검은 피부를 가졌을 것이다.<ref name="Brace">{{인용|last1=Brace |first1=Selina |last2=Diekmann |first2=Yoan |last3=Booth |first3=Thomas J. |last4=Faltyskova |first4=Zuzana |first5=Nadin |last5=Rohland |first6=Swapan |last6=Mallick |first7=Matthew |last7=Ferry |first8=Megan |last8=Michel |first9=Jonas |last9=Oppenheimer |first10=Nasreen |last10=Broomandkhoshbacht |first11=Kristin |last11=Stewardson |first12=Susan |last12=Walsh |first13=Manfred |last13=Kayser |first14=Rick |last14=Schulting |first15=Oliver E. |last15=Craig |first16=Alison |last16=Sheridan |first17=Mike Parker |last17=Pearson |first18=Chris |last18=Stringer |first19=David |last19=Reich |first20=Mark G. |last20=Thomas |first21=Ian |last21=Barnes  |title=Ancient genomes indicate population replacement in Early Neolithic Britain |journal=Nature Ecology & Evolution |volume=3 |pages=765–771 |year=2019 |issue=5 |pmc=6520225 |doi=10.1038/s41559-019-0871-9|pmid=30988490 }} [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6520225/bin/EMS82120-supplement-1.pdf Supplementary Material] (p.18-19): "This individual has light or blue/green eye colour, it is not light blue, there are elements of brown/yellow in the eye to give a proposed perceived green colour. Better coverage at the low sequenced marker would clarify this but blue/hazel cannot be ruled out. It is certainly not a brown eyed or clear blue-eyed individual...   Skin pigmentation  [assumptions about missing information omitted] The following range for skin pigmentation prediction is possible for this individual with these parameters:... Intermediate 0.152 - 0.038 Dark-Black 0.848 - 0.962 Final prediction: Dark/Dark-to-Black skin If we omit the three missing alleles, our tool produces 0.752 and 0.248 probabilities for the intermediate and dark-black category respectively, changing the prediction ranges to 0.752- 0.038 and 0.248-0.962. However, note that this completely removes the locus from the prediction model; hence the prediction will not perform optimally (how the prediction model was made). It is therefore best to have some allele present to infer the most probable range for Cheddar Man and we derive the ranges above from the extreme allele constellations only. Explanation: The missing loci certainly impact on this prediction; however, utilizing the input of all ancestral alleles is the preferred option over the use of the derived alleles at these loci – hence 0.152 for intermediate and 0.848 for Dark-to-Black would be the most probable profile. That being said a broad range is present in both the intermediate and dark-black categories due to the missing loci. Also, this effect of skipping a skin pigmentation prediction category with regards probability values, tends to be observed more often in admixed individuals. What is important to note is the input of the dark-black prediction is significant on the intermediate category and therefore it is acceptable to propose a dark complexion individual over an intermediate/light prediction even though the intermediate range is present. It is unlikely that this individual has the darkest possible pigmentation, but it cannot be ruled out. Better sequencing coverage would clarify to what degree this individual has a dark complexion."</ref>
