When Humans Were Prey
PBS Eons・10 minutes read
The discovery of the Taung Child challenged previous beliefs about early human ancestors and suggested they were preyed upon by other animals, not hunters. Evidence of predation in our evolutionary past has influenced our understanding of human evolution and the selective pressures that shaped our development as a species.
Insights
- The discovery of the Taung Child challenged the belief that early human ancestors were hunters, suggesting they were actually preyed upon by other animals, leading to a shift in understanding about human evolution.
- Evidence from damaged hominin fossils and further analysis revealed that early hominins were likely preyed upon by predators like hyenas, leopards, crocodiles, and even large birds of prey, prompting evolutionary adaptations such as becoming larger, bipedal, and developing speech to survive in a dangerous environment.

Predation in Human Evolution: A Paradigm Shift
- In 1924, a worker in South Africa discovered the fossilized skull of a juvenile hominin at a limestone quarry in Taung, which became known as the Taung Child, a significant find in human evolution.
- The Taung Child's discovery challenged previous beliefs about early human ancestors, suggesting they originated in Africa and were not hunters but preyed upon by other animals.
- Raymond Dart, an anthropologist, initially proposed the "Killer Ape Theory," suggesting early hominins were aggressive hunters, but later research by Sherwood Washburn and others indicated they were likely preyed upon by carnivores like hyenas.
- Discoveries of damaged hominin fossils, like SK 54 and OH8, led to the realization that our ancestors were more likely prey than hunters, with evidence pointing to attacks by predators like leopards and crocodiles.
- Further analysis in 1995 and 2012 revealed that the Taung Child was likely killed by a large bird of prey, while the Homo habilis foot found by the Leakeys showed marks consistent with crocodile attacks.
- Evolutionary adaptations, such as becoming larger, bipedal, and developing speech, were likely responses to the constant threat of predation faced by early hominins in Africa.
- Cooperation within groups and the ability to plan and communicate effectively may have been crucial adaptations that helped early hominins survive in a dangerous environment.
- Despite these adaptations, evidence like the Neanderthal child's finger bones with bird digestive tract marks from 115,000 years ago, suggests that our ancestors were still preyed upon by birds even in the Late Pleistocene.
- Understanding the signs of predation in our evolutionary past has shifted perspectives on human evolution, highlighting the selective pressures that shaped our development into the species we are today.
