How to play

• Each round shows three organisms. Two of them are close relatives.
• Tap the one that is not related to the other two.
• Watch out: the outsider always looks like one of the relatives. Nature often evolves the same shape twice; scientists call it convergent evolution.
• 10 rounds. 150 points per correct pick, plus 25 for each answer in your streak.

0 look-alike puzzles, each checked against current research on how these groups are related.
