The Evolutionary Process of Depression Paper
Depression is a mental adaptation that causes cognitive advantages. Research shows that about thirty to fifty percent of the people in the world have been diagnosed with major depression at a certain period in their lives.

The brain molecule is known to be associated with depression in which it promotes the symptoms. According to research, the rodents that do not have the receptor have fewer signs of depression. Hence, depression is caused by the increase of this brain receptor.....................GET A PLAGIARISM FREE COPY
