Fuyan Cave

Fuyan Cave is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Fuyan Cave rather than just read about it. In short: Fuyan Cave (Chinese: 福岩洞) is a complex of limestone caves in Tangbei village, Lefutang town, Daoxian, Hunan province, south central China famous for the discovery of the oldest evidence for unambiguously fully modern humans outside Africa. 47 human teeth, dating to between 80,000 and 120,000 years ago, were discovered at Fuyan Cave. The teeth are also unusual for showing signs of cavities, a feature typically not fo…

Key takeaways

  • Fuyan Cave belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Fuyan Cave to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Fuyan Cave from memory before moving on to harder problems.

Reference excerpt

Fuyan Cave (Chinese: 福岩洞) is a complex of limestone caves in Tangbei village, Lefutang town, Daoxian, Hunan province, south central China famous for the discovery of the oldest evidence for unambiguously fully modern humans outside Africa. 47 human teeth, dating to between 80,000 and 120,000 years ago, were discovered at Fuyan Cave. The teeth are also unusual for showing signs of cavities, a feature typically not found in teeth older than 50,000 years. However, a later study focusing on autosomal DNA analysis of the remains challenged this assertion, and found that the remains were younger than previously suspected.

Geology Fuyan consists of three caves connected by tunnels. The cave system has a volume of 3,000 m3 (110,000 cu ft) and ranges over 3 km2 (1.2 sq mi).

Discovery Fuyan Cave was discovered in 1984. The cave is located at latitude 25°39′02.7″N, longitude 111°28′49.2″E, at 232 m above sea level. The cave was excavated in 2011 over an area of 20 m2 (220 sq ft). The 2011 excavation revealed 5 hominin teeth and fossil remains from 39 different mammalians species, including some extinct ones. The cave was excavated in 2011 and in 2013. The teeth were all discovered in the middle cave.

Dating The teeth were dated by dating nearby stalagmites. The stalagmites were dated to at least 80,000 years. Since the teeth were found under rock over which the stalagmites had grown, the teeth must be older than 80,000 years old. More recent ancient DNA analysis of these remains indicated that the remains dated instead to the Holocene, although these recent findings are still under review. Specimen number FY-HT2 (9380±90 BP) in new study was incorrect identified as human teeth. Reconstructions of "deer-like" wear bear no resemblance to the preservational reality of the tooth FY-HT-2.

Implications The discovery is important for many reasons. Previous to this discovery, the earliest evidence for fully modern humans outside the Arabian Peninsula (Tianyuan Cave, Niah Cave, Mungo Man) dates to around 40,000 to 50,000 years, so the discovery at Fuyan Cave provides evidence showing that humans migrated out of Africa a lot earlier than previously assumed. Secondly, the finds at Fuyan Cave are much closer to modern humans than they are to contemporary finds at Xujiayao and Qafzeh. Thirdly, the discovery shows that modern humans arrived in southern China when there was an older, more primitive hominin present in northern China. Lastly, the discovery shows that modern humans were present in Asia at a time when there is no evidence for fully modern humans in Europe (43,000 BC), which is perhaps explained by the presence of Neanderthals in Europe preventing the entry of the modern humans.

Worked examples

Example 1 — a first encounter with Fuyan Cave

Start with the simplest possible case. Write down what Fuyan Cave claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Fuyan Cave before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Fuyan Cave ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Fuyan Cave

In research
Fuyan Cave appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Fuyan Cave in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Fuyan Cave is common in secondary-school and first-year university syllabi. It links to neighbouring topics Caves of Hunan, Dao County, Limestone caves, so understanding it makes those chapters shorter.
In everyday life
Look for Fuyan Cave outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
