How Hollow Bones Allowed Dinosaurs to Become Giants: The Evolutionary Story
Recently, researchers from the University of Bristol have discovered that hollow bones helped dinosaurs become giants. Many species of dinosaurs, such as the brachiosaurus, were enormous animals that could reach heights of up to 80 feet. Scientists have long debated how these creatures could have grown to such impressive sizes.
The researchers found that hollow bones helped reduce the weight of large dinosaurs while enabling them to become giants. By removing dense and heavy cortical bone, the animals were able to grow bigger without becoming too heavy or bulky. This adaptation allowed them to evolve into the giants we know today. The researchers also found evidence that the hollow bones of dinosaurs evolved faster than other parts of their bodies, suggesting that this adaptation played an important role in their success.
