  • An ancient species of great ape likely disappeared hundreds of thousands of years ago when climate change put their favorite fruits out of reach during dry seasons, scientists recently reported.
  • 2
  • The species is known as Gigantopithecus blacki.
  • 3
  • It once lived in southern China.
  • 4
  • It stood 3 meters tall and weighed up to 295 kilograms.
  • 5
  • It represents the largest great ape known to scientists.
  • 6
  • "It's just a massive animal - just really, really big," said Renaud Joannes-Boyau.
  • 7
  • He is a researcher at Australia's Southern Cross University.
  • 8
  • He helped write the study, which recently appeared in the publication Nature.
  • 9
  • But its size may also have been a weakness.
  • 10
  • Joannes-Boyau said, "When food starts to be scarce, it's so big it can't climb trees to explore new food sources."
  • 11
  • The huge apes likely looked similar to the modern orangutan.
  • 12
  • It survived for around 2 million years in the forested land of China's Guangxi area.
  • 13
  • They ate plants that included fruits and flowers --- until the environment began to change.
  • 14
  • Starting about 600,000 years ago, Guangxi's forests began producing fewer fruits.
  • 15
  • The area was experiencing more periods of dry weather.
  • 16
  • Researchers examined pollen and sediment found in underground areas called caves to learn more about the changes and their effects.
  • 17
  • The giant apes did not disappear quickly, the researchers say.
  • 18
  • They likely went extinct sometime between 215,000 and 295,000 years ago.
  • 19
  • As the climate changed, smaller apes may have been able to climb trees to search for different food.
  • 20
  • But the researchers found that the giant apes ate more food that provided less nutrients.
  • 21
  • That less nutritious food included tree bark and thin grasses called reeds.
  • 22
  • "When the forest changed, there was not enough food preferred by the species," said Zhang Yingqi of China's Institute of Vertebrate Paleontology and Paleoanthropology.
  • 23
  • He helped write the study.
  • 24
  • Most of what scientists know about the extinct great apes comes from studying their remains, or fossils.
  • 25
  • The fossilized bones they studied included teeth and four large lower jaw bones.
  • 26
  • All of the fossils were found in southern China.
  • 27
  • No complete skeletons have been found.
  • 28
  • Between around 2 million and 22 million years ago, many species of great apes lived in Africa, Europe, and Asia, fossil records show.
  • 29
  • Today, only gorillas, chimpanzees, bonobos, orangutans and humans remain.
