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.
Weight gain, low bone density, fatigue, joint pain, and depression are surprisingly just a few symptoms of vitamin D deficiency. Long-term use of antiepileptic drugs (AEDs) is associated with vitamin D deficiency, even in sub-tropical countries, according to a study at the University of Malaya.
