Can you solve the mystery? Scientists solve mysteries by collecting evidence, making observations, and analyzing similarities and differences. Then they develop theories that explain and predict patterns in nature. By taking careful notes about everything around him and using his creativity and inventive thinking, Charles Darwin was able to consider the evidence and develop his famous theory of evolution through natural selection.

Your challenge: Solve the mystery by examining the evidence.
