Botany

Before photosynthesis evolved in cyanobacteria around 2.7 billion years ago, Earth's atmosphere contained virtually no free oxygen. The 'Great Oxidation Event' roughly 2.4 billion years ago, driven by cyanobacterial photosynthesis, transformed the atmosphere and enabled the evolution of complex aerobic life. Today, photosynthetic organisms — plants, algae, and cyanobacteria — collectively produce about 300 billion tonnes of oxygen per year, of which roughly half comes from ocean phytoplankton.

This 65-acre park, dedicated to preserving native flora and fauna, was officially opened by Queen Elizabeth II in 1994. It features a unique 'colour garden,' a woodland trail, and a lake.

Despite its common name, the Bermuda Blue-Eyed Grass is actually a member of the iris family, not a true grass. This small, vibrant blue flower blooms in spring and is a beloved symbol of the island's natural beauty.

Encyclia cochleata, commonly known as the Black Orchid, is renowned for its unique appearance, featuring sepals and petals that are greenish-yellow and a lip that is nearly black. It thrives in the country's humid, tropical climate.

This citrus fruit, a natural hybrid of the pomelo and sweet orange, was first documented in Barbados in the 18th century. It was initially called "forbidden fruit" or "shaddock" before acquiring its current name, making Barbados its likely birthplace.

These iconic 'tree of life' species are prevalent in many Angolan regions, revered for their longevity, distinctive bottle-shaped trunks, and their fruit's nutritional value. They are a symbol of resilience and natural heritage, often central to local folklore.

This unique plant, endemic to the Namib Desert, can live for over 1,500 years and has only two leaves that continuously grow throughout its lifespan. It's a botanical anomaly, perfectly adapted to extreme desert conditions and a living fossil.

Near the village of Fagatogo, this colossal tree, with its sprawling aerial roots and massive canopy, is a natural wonder and a significant landmark. It provides extensive shade and a habitat for various local wildlife, revered by the community.

Native to Africa and Australia, their thick, bottle-shaped trunks and sparse, gnarled branches resemble roots reaching skyward, especially when leafless. This unique appearance has earned them the nickname "the tree of life" due to their longevity and resourcefulness.

Many natural spirals, like those found in pinecones and sunflowers, exhibit Fibonacci numbers, where consecutive numbers (like 3, 5, 8, 13) are often odd, making even numbers less common in these specific patterns.
