Fans of the band Tool probably know that band leader Maynard James Keenan wrote a song with the lyrics and time signature arranged in the numbers of the Fibonacci Sequence.Īsteroxylon mackiei was a clubmoss that featured among the world’s oldest leaf-bearing plants. ![]() The Fibonacci Sequence has also been found in spiral galaxies and large hurricanes. This results in continuous spirals of organs, with the number of clockwise and anticlockwise spirals forming consecutive numbers in a Fibonacci sequence. In most existing plant species, organs emerge at 137.5° from the previous organ. They characterize the Fibonacci spiral as being found in the arrangement of their organs around their stems. ![]() Image credit: Turner et al., doi: 10.1126/science.adg4014. “Based on their widespread distribution it has long been assumed that Fibonacci spirals were an ancient feature that evolved in the earliest land plants and became highly conserved in plants.” Asteroxylon mackiei.
