Chinese Academy of Sciences yeren expedition
In 1977 the Chinese Academy of Sciences sent a team of over 100 people into Shennongjia to search for the 'wild man'.
1977 CE · 31.60, 110.40 · status: official
The account
They gathered hair, footprints and droppings but no animal; later analyses of hair samples pointed to known species.
The researched reading
A serious state search that found traces but no creature. Known forest animals and a strong local legend explain the reports better than an undiscovered ape.
| Explanation | Weight | Why |
|---|---|---|
| Something known, misidentified | 40% | Shennongjia holds black bears, macaques and golden snub-nosed monkeys, all of which can look like a hairy “wild man” in glimpses; hair samples collected by expeditions were attributed to known animals in later analyses. |
| A cultural story | 24% | Wild-man lore in Hubei long predates the expedition; a state search raised its profile and invited more reports shaped by the legend. |
| Undetermined | 13% | The share the reading had given to fabrication on doubt rather than evidence: the record does not settle it either way. |
| Perception, memory or mind | 10% | Expectation after wide publicity makes hikers and villagers read shapes and sounds as the wild man. |
| An unknown or out-of-place animal | 6% | Gigantopithecus once lived in southern China and the forests are large and rugged, but a hundred-strong expedition found no body, bones or clear photographs. |
| A hoax or fabrication | 5% | Some footprints and later reports could be fabricated, especially as yeren became a local tourism brand. |
| Genuinely anomalous | 2% | The question is whether an ape exists, not whether anything beyond biology is involved. |
Official position: The Chinese Academy of Sciences expedition gathered hair, footprints and droppings but no animal; it did not confirm the yeren.
