There’s a reason Evolution hasn’t won previously… I am not a fan of this theme (or rather, my imagination is just weak).

Some quick ideas:

• Adapt
• Change
• Survive
• Growth
• Learning
• Species
• Time
• Good -> evil
• Fungus
• Cooking skills
• Digital devices
• Graphics
• Lizards
• Moths
• Plants
• Roles in a company (engineer -> sr. engineer -> … -> boss)
• Relationship (dating -> engaged …)
• Amoeba

Something will come up!
