R M Whiteside,J Forsyth,A Wilson is not present in any other group of plants, where the gametophytic generation is dominant and lack vascular tissues. Despite their fragile appearance, they present an extensive fossil record that attests their persistence and adaptation to varied climatic types and habitats. The record of bryophyt
