It's a World full of Plants
Plant evolution, a process spanning billions of years, traces the journey from aquatic green algae to the diverse land plants we see today. This journey involved several key adaptations, including the development of vascular tissue, seeds, and flowers, all facilitating plant success on land. The first land plants were likely simple, non-vascular bryophytes like mosses and liverworts, followed by the evolution of more complex, vascular plants. This collection features some of the plant groups propduct of this amazing evolutionary process.
Orchids: Jewels of Evolution
Orchids, a diverse group of flowering plants, have a rich evolutionary history, originating roughly 112 million years ago, during the Cretaceous period. Their evolution has been shaped by factors like adaptation to various environments, especially epiphytic lifestyles (growing on other plants), and the development of specialized pollination mechanisms like pollinia. The majority of orchid diversity, however, is inferred to have originated within the last 5 million years, with the American and Asian tropics experiencing the highest speciation rates.
Roses
There are estimated to be over 30,000 cultivated rose varieties (cultivars) and around 150 species of wild roses. This vast diversity includes a wide range of colors, fragrances, and growth habits. Let's explore this amazing diversity together ! This selection includes some of the more beautiful roses I've seen. More of them, are from my country, Ecuador.
Fungi and Relatives
There are an estimated 2.5 million species of fungi worldwide, with only about 155,000 currently named. This number is an estimate, as many fungi remain undescribed due to their cryptic and microscopic nature. New species are still being discovered, and it is estimated that it would take 750-1000 years to name all of them at the current rate of discovery.
Fungi first appeared on Earth around 1.5 billion years ago, with evidence suggesting their evolution from a single common ancestor with animals and a separate group of living organisms according to Fungimap. While fossils of land-dwelling fungi are scarce, evidence suggests they may have colonized land as early as 635 million years ago, possibly during the Ediacaran period. The oldest undisputed fungal fossils are approximately 400 million years old.
