WHAT’S BEING CLAIMED:
- A popular custom during Thanksgiving calls for a wishbone breaking — with the person holding the longer portion entitled to make a wish.
- A wishbone, or a furcula, is a one-piece, oddly-shaped forked bone located between the neck and breast of a bird.
- According to paleontology, the wishbone dates back over 150 million years to meat-eating dinosaurs including the baddest of them all — the Tyrannosaurus Rex.
A popular tradition after Thanksgiving is the wishbone breaking. The idea is for two people to grab the opposite ends of a wishbone and pull until it splits in two. The person who ends up having the longer portion is entitled to make a wish.
Technically, the wishbone is called a furcula — a forked bone located between the neck and breast of a turkey, or a bird, in general. It is formed by the fusion of two collarbones at the sternum.
A furcula is a connecting point for muscles and a strengthening brace for wings. According to experts, it is elastic and acts as a spring that stores and releases energy during flapping.
The furcula plays a major role in a bird’s flight mechanics that’s why scientists previously thought that the furcula was only found in birds. Backed by paleontology, the furcula dates back more than 150 million years tolong-extinct meat-eating predators — the dinosaurs. That includes the Tyrannosaurus Rex and Velociraptor.
The T-rex is often featured in films as the meanest and most ferocious two-legged carnivore predator. But how come they have furculas when these dinosaurs can’t fly? Paleontologists say that their furculas likely acted as structural supports as the dinosaurs held their prey. These scientists also suggest that the T-rex was partially covered in a coat of feathers.
Though people will not easily accept the idea of a feathered T-rex, the furcula is a major component of the commonly accepted theory that Thanksgiving turkeys are the descendants of dinosaurs.
