Two Words and a Sketch That Changed Biology Forever

Charles Darwin’s Tree of Life: Before there were textbooks and PowerPoint slides on the transmutation of species, there was a simple yet groundbreaking sketch. This 8x10 canvas print is a beautifully minimalist reproduction of the first-known evolutionary tree, drawn by Darwin himself. With the handwritten words “I think” above it, this piece is more than just decor—it’s a tribute to scientific curiosity, discovery, and the power of questioning everything.

3 Creative Ways to Use This Print in Your Classroom

1. The “I Think” Discussion Starter

   At the beginning of your evolution unit, ask students to write down their own “I think” statements about life, adaptation, and change over time. Compare their ideas to Darwin’s theories as the unit progresses.

   
   

2. Scientific Method Connection

   Use this print as an example of how great scientific discoveries begin. Pair it with lessons on hypothesis formation, observation, and the process of scientific inquiry.

   
   

3. Cross-Curricular Connections

   Challenge students to connect the Tree of Life to other disciplines—how does it relate to history, philosophy, or even literature? Assign creative writing prompts where students imagine themselves as Darwin, making this discovery for the first time.

This Tree of Life print is a daily reminder to stay curious, ask big questions, and explore the world like a scientist. Whether you’re teaching evolution, sparking classroom discussions, or just looking for the perfect science-themed decor, this print belongs in your learning space.
