Evolutionary history

Evolutionary history

The first known forests on Earth arose in the Late Devonian (approximately 380 million years ago), with the evolution of Archaeopteris.[23] Arc

haeopteris was a plant that was both tree-like and fern-like, growing to 10 metres (33 ft) in height. Archaeopteris quickly spread throughout the world, from the equator to subpolar latitudes.[23] Archaeopteris formed the first forest by being the first known

species to cast shade due to its fronds and forming soil from its roots. Archaeopteris was deciduous, dropping its fronds onto the forest floor. The shade, soil, and forest duff from the dropped fronds created the first forest.[23] The shed organic matter

altered the freshwater environment, slowing it down and providing food. This promoted freshwater fish.[23]
