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.
Researchers believe that without adequate vitamin D to help absorb it, the extra calcium settles in the arteries instead of the bones. There, it helps form plaques that threaten the heart and brain. Excess calcium can also cause muscle pain, mood disorders, abdominal pain and kidney stones.
