How Pandas Became Bamboo Eaters: Stable Isotopes Rewrite the Diet Evolution Story
The giant panda's transition from omnivore to bamboo specialist is far more recent — and far less straightforward — than previously believed. Stable isotope analysis of fossil panda bones, led by Wei Fuwen's team at the Institute of Zoology, Chinese Academy of Sciences, has overturned the traditional narrative: until approximately 5,000 years ago, pandas were omnivores with a diet breadth three times wider than today's. This article traces the fossil evidence, the isotopic methodology, and the story of how the panda — a living contemporary of saber-tooth tigers and mammoths — survived by changing what it ate.
