In fact, these patterns are consistent enough that cold, hard math can predict organic growth fairly well. One assumption that has been central to the study of phyllotaxis, or leaf patterns ...

Scientists made fake leaves and dropped them in water tanks to observe how different shapes move as they sink.

An unusual arrangement of leaves in a 407-million-year-old fossilized plant is complicating scientists’ understanding of plant evolution. Most land plants living today have spiral patterns ...

As a result, botanists and foresters have developed terms for the patterns and shapes used in tree identification, and many of those terms are used when observing a tree's leaves. Some tree ...

Today, only a very few plants don’t follow a Fibonacci pattern. Spirals occur frequently in nature and can be seen in plant leaves, animal shells and even in the double helix of our DNA.
