Keep your observation simple and specific and it will be easier to generate hypotheses and to test these hypotheses. … To qualify as an explanation, evolution first needs to explain how original life came from inorganic matter. These social influences represent a third type of vulnerability in the biopsychosocial model. 3.3. A hypothesis is not just any explanation; it should fit into the context of a scientific theory.
