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.
Vitamin D is needed to help the body better absorb calcium and keep the bones strong. Without the proper amount of vitamin D, a person may experience detrimental effects on his health. It can lead to severe problems like osteoporosis, arthritis, depression or even high blood pressure.
