Traditional evolutionary scenarios posit that land plants emerged from land plant-like relatives, the charophytes. New phylogenies suggest a closer affinity to simpler pond scum relatives, and evidence the gradual assembly of the land plant genome, revealing a phenotypic simplification from the complex ancestors envisaged by traditional scenarios.
传统的进化情景假设,陆生植物是从类似陆生植物的亲戚——轮藻中进化而来的。新的系统发育关系表明,它们与更简单的池塘浮渣状生物的亲缘关系更为密切,并且为陆生植物基因组的逐步组装提供了证据,揭示了从传统情景中设想的复杂祖先那里逐渐出现的表型简化。
