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 at normal doses usually has no side effects. If you have any unusual effects, contact your doctor or pharmacist promptly. If your doctor has directed you to take this medication, remember that he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Too much vitamin D can cause harmful high calcium levels. Tell your doctor right away if any of these signs of high vitamin D/calcium levels occur: nausea/vomiting, constipation, loss of appetite, increased thirst, increased urination, mental/mood changes, unusual tiredness.
