On July 31, 2014, scientists reported details of the evolution of birds from other theropod dinosaurs. Among the features linking theropod dinosaurs to birds are a furcula (wishbone), air-filled bones, brooding of the eggs, and (in coelurosaurs, at least) feathers.
Vitamin D Deficiency. People who are vitamin D-deficient can suffer some adverse effects, such as being more prone to certain cancers and possibly being affected by depression or other mood disorders, according to studies reported by MayoClinic.com.
Drugs That Interact With Vitamin D. Some drugs cause your body to absorb less vitamin D. These include laxatives, steroids, and anti-seizure medicines. If you take digoxin, a heart medicine, too much vitamin D can raise the level of calcium in your blood and lead to an abnormal heart rhythm.
