Here’s the tradeoff if you’re a male bee. The female honeybee does not need a partner to reproduce. She can lay an unfertilized egg, and it will hatch male. If she lays a fertilized egg, it will hatch female. Thus every male bee has one parent and every female bee, two. The male bee never has a father and never has a son. He can have friends, if he wants.
His reward is to anchor a delicate webbing. Tracing a male bee’s ancestry reveals a pattern of cracked glass: He has one parent, two grandparents, three great-grandparents, five great-great grandparents, eight great-great-great grandparents, and so on. Every male bee is the start of Fibonacci’s sequence: 1, 1, 2, 3, 5, 8, 13, 21, et cetera. Every number the sum of the two numbers before it. What Fibonacci said of rabbits, we can see in bees.
Fibonacci first posed it this way: If a newborn pair of rabbits is placed in a field to mate when they are one month old, and a new pair of rabbits repeats the sequence every month after, how many pairs will there be after a year? I don’t know the answer, but I like how he specified the rabbits have to be in a field. Writing a book meant to convince the public of the superiority of Hindu-Arabic mathematics, Fibonacci takes a moment to set the scene. What made him think it was important to put the rabbits in a field? Was it a memory from school? Some long-ago emphasis a favorite teacher placed on setting? Or was it the feeling, however latent, that these patterns respond to nature as it is, as much as they dictate how it will be?
