Ancient Ostrich Nest Unearthed in Andhra Pradesh
- Context (IE): Archaeologists have unearthed a 41,000-year-old ostrich nest in Prakasam, Andhra Pradesh. This discovery is considered the world’s oldest known ostrich nest.
Megafauna
- Megafauna refers to animals weighing over 50 kg, a term first coined by Alfred Russel Wallace in 1876.
- These large animals are classified as megaherbivores, mega carnivores, or mega omnivores based on their diets. Ostriches, weighing 90-140 kg and 7-9 feet tall, fall into the mega omnivore category.
Co-evolution hypothesis
- A study by Yale and the Smithsonian’s National Museum of Natural History (2020) suggests large animal extinction in India began around 30,000 years ago, coinciding with human arrival.
- This research supports the “co-evolution hypothesis,” which proposes that fauna’s resilience to extinction may have resulted from coevolution with hominins (humans and their relatives).
- It proposes that geographic isolation and environmental changes may have accelerated extinction.
