Abstract

Bonacorsi et al. describe a new fossil from the Early Devonian that provides the earliest clear evidence for more advanced reproductive biology in land plants. The plant produced multiple spore size classes, which is an essential innovation necessary for all advanced plant reproductive strategies, including seeds and flowers.

摘要

博纳科尔西等人描述了一种来自早泥盆世的新化石，它为陆地植物更先进的生殖生物学提供了最早的明确证据。该植物产生了多个孢子大小类别，这是所有先进的植物生殖策略（包括种子和花朵）所必需的基本创新。
