Two-hour intensive course (in English) incl. the use of stereo microscopes, by Arve Elvebakk in Tromsø Arctic-Alpine Botanic Garden. Wednesday, July 3, at 2.00-4.00pm.
The Green Evolution – from cyanobacteria to orchids.
The cyanobacteria are 3.5 billion years old, the first organisms to have photosynthesis, produce oxygen, later ozon, and that fixated nitrogen, hence paving the way for further life.
Later the green algae arrived, then mosses, ferns, coniferous tree and flowering plants….
Why were the mosses an evolutionary cul-de-sac? Why does ferns grow only along cracks in the rocks of the garden? Why is the beautiful ballflower in the picture below a primitive flower, while the anonymous grasses are more advanced and the orchid flower the most advanced of all flowers?
