100+ Mind-Blowing Analogy Examples in Biology: A Must-Read for Science Enthusiasts

Your search for analogies in biology ends here!

When I began seriously researching the topic of metaphors in biology, I was surprised by how much was written about the usefulness of metaphors and analogies in helping science students grasp new concepts and furthering creative reflection. 

Beyond wonderful examples of how using metaphors and analogies can help explain complex concepts with real creativity. For instance, 

• Richard Feynman compared a magnified drop of water to the brimming energy of a “crowd at a football game as seen from a great distance” (Feynman, Leighton, and Sands, 2011)
• Stephan Hawking made the analogy of maths underlined the curvature of space-time to orange: smooth from a distance, bumpy and wrinkled on close inspection (Hawking and Jackson, 1993).
• Richard Dawkins spoke of the selection of genes across generations as a series of sieves: unhelpful genes may make it by chance through a few sieves but not a thousand in succession (Dawkins 1996). 

In all these examples, phenomena that, for many, were too abstract or vast to understand were made palpable and approachable by the masses. 

To continue the tradition with legends, I’ve created 100 more analogies in Biology to help you understand the concepts, with the help of analogenie. 

Choose from the collection of analogies, blend in some of your own ideas, and you’re good to go!

Use it on any of your research papers, essays, homework and impress the readers.
