The findings revealed that leaves and reproductive structures in Asteroxylon mackiei, were most commonly arranged in non-Fibonacci spirals that are rare in plants today. The site contains evidence of some of the planet's earliest ecosystems-when land plants first evolved and gradually started to cover the Earth's rocky surface making it habitable. The exceptionally preserved fossil was found in the famous fossil site the Rhynie chert, a Scottish sedimentary deposit near the Aberdeenshire village of Rhynie. Using digital reconstruction techniques the researchers produced the first 3D models of leafy shoots in the fossil clubmoss Asteroxylon mackiei-a member of the earliest group of leafy plants. Our analysis of leaf arrangement in Asteroxylon shows that very early clubmosses developed non-Fibonacci spiral patterns' stated Holly-Anne Turner. Using these reconstructions we have been able to track individual spirals of leaves around the stems of these 407-million-year-old fossil plants. 'The clubmoss Asteroxylon mackiei is one of the earliest examples of a plant with leaves in the fossil record.

However, an international team led by the University of Edinburgh including University College Cork (UCC) Holly-Anne Turner and researchers at University Münster, Germany and Northern Rogue Studios, U.K., has overthrown this theory with the discovery of non-Fibonacci spirals in a 407-million-year-old plant fossil.

Why Fibonacci spirals, also known as nature's secret code, are so common in plants has perplexed scientists for centuries, but their evolutionary origin has been largely overlooked.īased 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. Sunflower heads, pinecones, pineapples and succulent houseplants all include these distinctive spirals in their flower petals, leaves or seeds. Spirals are common in plants, with Fibonacci spirals making up over 90% of the spirals. Named after the Italian mathematician, Leonardo Fibonacci, this sequence forms the basis of many of nature's most efficient and stunning patterns.

Whether it is the vast swirl of a hurricane or the intricate spirals of the DNA double-helix, spirals are common in nature and most can be described by the famous mathematical series the Fibonacci sequence. This negates a long-held theory about the evolution of plant leaf spirals, indicating that they evolved down two separate evolutionary paths. Instead, the ancient plants were found to have another type of spiral. The findings indicate that the arrangement of leaves into distinctive spirals, that are common in nature today, were not common in the most ancient land plants that first populated the Earth's surface. student at University College Cork (UCC) Holly-Anne Turner is the first author on the study and conducted the research while an undergraduate student and Research Assistant at the University of Edinburgh. The research published in the journal Science overturns a long-held theory around a famous pattern in nature.
