“Tessellations are patterns formed by repeating tiles all over a flat surface. … While common in art and design, exactly repeating tilings are less easy to find in living things” (Wikipedia contributors, “Patterns in nature,” Wikipedia, The Free Encyclopedia, accessed March 16, 2024, https://en.wikipedia.org/w/index.php?title=Patterns_in_nature&oldid=1189548118). Tessellations fit together perfectly because the shape repeats. One example of a repeating pattern in nature is the perfectly octagonal honeycomb, built by bees for the purpose of saving space and structural integrity. Although the bees seem identical, there are several differences between bees even in one hive, including physical and occupational differences.
