Life on Earth is full of incredible patterns that seem to repeat themselves across different organisms. One such pattern is the tiled structures found in a variety of creatures, from mirror spiders to chitons to sharks. These geometric patterns, made up of discrete structural pieces separated by softer seams, are not just visually appealing but also serve important functions in the organisms that possess them.
Researchers have recently compiled a catalog of 100 examples of these tiled patterns, showcasing their presence in animals, plants, microbes, and even viruses. What’s fascinating is that these patterns have evolved independently in different lineages, indicating a convergence towards similar solutions driven by geometry and growth. For example, the predominantly six-sided patterns seen in sharks and rays efficiently cover curved surfaces, while the alignment of tile borders with regions of cell growth allows tissues to expand and function properly.
From the articulated shell plates of chitons to the tessellated cartilage of sharks, these patterns help organisms see, move, and protect their bodies. By balancing rigidity with flexibility, these structures provide the necessary support and mobility required for survival. The researchers behind this study hope that their online catalog becomes a valuable resource for scientists and enthusiasts to recognize and appreciate these intricate patterns in nature.
Understanding these tessellated structures not only sheds light on the remarkable diversity of life on Earth but also highlights the universal principles of geometry and growth that underlie the evolution of these patterns. As we continue to explore the wonders of the natural world, we can marvel at the beauty and complexity of these geometric masterpieces that have emerged through millions of years of evolution.
