Part A — Multiple Choice

1. C) Approximately 10,000 years old. The skeleton was discovered in 1903 in Gough's Cave, Somerset, and dated to approximately 10,000 years ago — one of the oldest complete human skeletons found in Britain.
2. B) Dark to black skin, blue or green eyes, and dark curly hair. The 2018 ancient DNA analysis conducted by the Natural History Museum London and University College London determined this was Cheddar Man's most likely physical appearance.
3. C) Western Hunter-Gatherers. Cheddar Man belonged to the Western Hunter-Gatherer population — the genetically distinct group that inhabited western and central Europe during the Mesolithic period.
4. C) Relatively recently — within the last 6,000 to 8,000 years, driven by migration and natural selection. Lighter skin variants were introduced by Anatolian farmers around 6,000 BCE and further spread by the Yamnaya pastoralists around 3,000 BCE — not an ancient characteristic of European populations.
5. B) Gough's Cave, Cheddar Gorge, Somerset, England. This is where the skeleton was discovered in 1903.
6. C) Public and media reaction from outside the scientific community. The scientific community was largely unsurprised — the controversy came entirely from political commentators, right-wing media, and online communities whose assumptions about European identity were challenged.
7. B) SLC45A2 and SLC24A5. These are the primary gene variants associated with lighter skin pigmentation in modern European populations. Ancient DNA shows these variants were largely absent in Western Hunter-Gatherer populations like Cheddar Man.

Part B — Short Answer Key Points

8. Question: What is ancient DNA analysis and how was it used to determine Cheddar Man's appearance?
   A strong answer should include:
   • Ancient DNA analysis is the process of extracting and sequencing genetic material from ancient skeletal remains
   • Scientists extracted DNA from Cheddar Man's petrous bone — the dense bone behind the ear that preserves genetic material better than most tissue
   • By analyzing gene variants associated with skin pigmentation, eye color, and hair texture — particularly SLC45A2 and SLC24A5 — researchers determined his likely physical appearance
   • The analysis showed he most likely had dark to black skin, blue or green eyes, and dark curly hair
9. Question: What is the difference between a scientific controversy and a cultural or political controversy?
   A strong answer should include:
   • A scientific controversy involves disagreement among experts about methodology, data, or interpretation — resolved through peer review, replication, and evidence
   • A cultural or political controversy involves disagreement about what findings mean for identity, ideology, or social narratives — not about the science itself
   • The Cheddar Man reaction was a cultural controversy — the scientific community was largely unsurprised; the controversy came from outside it, from people whose assumptions about European identity were challenged
   • Attacking the science rather than engaging with the evidence is a sign of a cultural controversy, not a scientific one
10. Question: How does the evidence about Western Hunter-Gatherers challenge the assumption that pale skin is ancient and fundamental to European people?
    A strong answer should include:
    • Western Hunter-Gatherers — the original post-Ice Age inhabitants of Europe — predominantly had dark skin, as shown by ancient DNA studies across Britain, Ireland, France, Spain, and beyond
    • The gene variants associated with lighter skin were largely absent in this population
    • Lighter skin became widespread only within the last 6,000 to 8,000 years — introduced by Anatolian farmers around 6,000 BCE and Yamnaya pastoralists around 3,000 BCE
    • Modern Europeans are a genetic mixture of all three ancestral populations — light skin is a relatively recent development, not an ancient or original European characteristic
