The ancestry of a male bee matches the Fibonacci sequence. It has one parent, two grandparents, three great grandparents, five great great grandparents, eight great great great grandparents, etc. I found this fascinating and was thus inspired to design this pattern poster that depicts the phenomenon. The relative space between each bar represents the sequence. The typography also matches the sequence. And there is, pulled from Wikipedia, and explanation of how it works.

A print of this can be purchased at Society6.
