A cladogram is a visual representation of the relationships between organisms and also shows how organisms evolved from common ancestors. <em><u>Points where organisms branch off are called </u></em><em><u>nodes </u></em><em><u>and these nodes branch off show the last common ancestor among the organisms.</u></em>After each node, the line moves forward, which indicates where the organisms diverge. This means at this point, the organisms evolved traits that separates them from the common ancestor.
