RETURN TO WATER. "The plant kingdom contains multicellular phototrophs that usually live on land. The earliest plant fossils are from terrestrial deposits, although some plants have since returned to the water." https://lnkd.in/d6dpu-q View in LinkedIn

CONFUSING. "Aquatic plants are notoriously difficult to study systematically due to convergent evolution and reductionary processes that result in confusing arrays of morphological features.” http://www.pnas.org/content/88/22/10119.full.pdf View in LinkedIn

THE GREAT ALGAL JUMP. "Algae dominated the oceans of the precambrian time over 700 million years ago. Between 500 and 400 million years ago, some algae made the transition to land, becoming plants by developing a series of adaptations to help them survive out of the water." https://lnkd.in/d6dpu-q View in LinkedIn

CANDIDATE ALGAE. "Fossil and biochemical evidence indicates plants are descended from multicellular green algae. Various green algal groups have been proposed for this ancestral type, with the Charophytes often being prominently mentioned. Cladistic studies support the inclusion of the Charophytes (including the taxonomic order Coleochaetales) as sister taxa to the land plants." https://lnkd.in/d6dpu-q View in LinkedIn

ALGAE ANCESTORS. "Land plants, also called embryophytes, descended from freshwater algae about 480 Ma. Most of the major phylogenetic groups of land plants now have at least one high-quality draft or reference genome sequence." http://rstb.royalsocietypublishing.org/content/369/1648/20130355.short View in LinkedIn

EARLY PLANT SEEDS. "However, do we generally appreciate the evolution of this adaptation, much less the diverse effects it has had on terrestrial ecosystems and, indeed, our own culture? No. We take it for granted, even though land plants evolved the seed millions of years before the first amniote is recorded in the fossil record." https://academic.oup.com/bioscience/article/65/6/626/304981/Seeds-and-Fruits-Underwriting-the-Diversity-of View in LinkedIn
