<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">genesis man</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for adam that I've seen before include "Early man" , "one might confuse with total stranger" , "__ Smith, author of The Wealth of Nations" , "The first known ancestor" , "who was tempted by mate?" .)
