Turkey facts on Thanksgiving

Turkeys can fly.
Wild turkeys feed on the ground, which might explain the myth of their flightlessness. They can in fact soar for short bursts at up to 55 mph. But their tendency to stay on or near the ground contributed to successful hunting that brought the wild population of turkeys down to about 30,000 in the 1930s. There are now 7 million of them.

Dark meat is rare because ...
Meat is muscle. And muscle is fed by blood. In the blood is myoglobin, which binds with oxygen and stores it in muscles for when it's needed. Myoglobin also makes meat dark. Muscles that are used most, like those in drumsticks (legs), have more myoglobin. Domestic turkeys are too fat to fly, so they don't use their breast muscles much, which is why breast meat is white. The breast of a wild turkey is entirely different, darker (and far tastier for those who are game).

Turkey eggs wouldn't sell.
Chickens are champion egg-producers. Turkeys, not so good. Turkey eggs are bigger, so their nests tie up coop space. And farmers have learned that they make more raising turkeys for meat rather than eggs. Oh, and some turkeys are protective of their eggs, making the gathering more challenging.

It's not the turkey that makes you sleepy.
Turkey contains a natural chemical called tryptophan, which we need to build proteins for our bodies. Indeed, tryptophan is also related to the production of serotonin, which helps us sleep. But all meat has about the same amount of tryptophan. Cheddar cheese has a lot more. What really makes you sleepier after a Thanksgiving meal compared to other meals is eating too many carbohydrates, from potatoes to pies. Alcohol can contribute, too.

Dinosaurs had wishbones too.
The wishbone, called a furcula, is the fusion of two collarbones at the sternum. It's where a bird’s flying muscles hook up. It's elastic and great for flapping. Turns out T. Rex and the Velociraptor had wishbones, too. While they didn't fly, this fairly recent discovery is one of the many bits of evidence that shows birds evolved from dinosaurs.
