DESCRIPTION:The origin of land plants was a formative episode in Earth his
 tory\, forever changing biogeochemical cycles and creating habitats for an
 imals. However\, until recently\, the timescale of early land plant evolut
 ion has been unclear because of our uncertain knowledge of the relationshi
 ps between the fundamental lineages of land plants\, itself impacting upon
  our perception of the ancestral land plant. Based on new data and methods
  it has been able to resolve that bryophytes and tracheophytes comprise th
 e two fundamental lineages of land plants that diverged in the late Cambri
 an to early Ordovician and that none of the living bryophytes or tracheoph
 ytes are representative of the ancestral land plant in terms of their anat
 omy\, physiology\, genome or developmental biology. This challenges the se
 lection of models for understanding the impact of land plants on the Earth
  system.
