• [Evidence of evolution: Grades 13-16] There is a fit between organisms and their environments, though not always a perfect fit.
• [Mechanisms of evolution: Grades 13-16] Over time, the proportion of individuals with advantageous traits may increase (and the proportion with disadvantageous traits may decrease) due to their chances of surviving and reproducing.
• [Mechanisms of evolution: Grades 13-16] Sexual selection occurs when selection acts on characteristics that affect the ability of individuals to obtain mates.
• [Nature of science: Grades 13-16] Scientific knowledge is open to question and revision as we come up with new ideas and discover new evidence.
• [Nature of science: Grades 13-16] Scientists test their ideas using multiple lines of evidence.
• [Nature of science: Grades 13-16] Scientists may explore many different hypotheses to explain their observations.
• [Studying evolution: Grades 13-16] Our knowledge of the evolution of living things is always being refined as we gather more evidence.
