Genetic mutation led to the first land-based plants

See:

Article reads: Guoxiong Chen, a doctoral student working at Haifa University’s Institute of Evolution, found the gene in wild barley more than a decade ago, but now has identified a mutation of that gene that builds a cuticle, a hard protecting layer that helps the plant retain water. Without the cuticle, the plant would expel all its water and could not survive in the air. Chen named the mutation Eibi1 after his doctoral advisor at Haifa, Eviatar Nevo.
