Fossils of Earliest Land Plants Discovered in Argentina
The earliest plants to have colonized land have been found in Argentina.
The discovery puts back by 10 million years the colonization of land by
plants, and suggests that a diversity of land plants had evolved by 472
million years ago.
The newly found plants are liverworts, very simple plants that lack
stems
or roots, scientists report in the journal the New Phytologist. That
confirms liverworts are likely to be the ancestors of all land plants.
The appearance of plants that live on land is among the most important
evolutionary breakthroughs in Earth's history. Land plants changed
climates
around the globe, altered soils and allowed all other multi-cellular
life to
evolve and invade almost all of the continental land masses.
