Chapter 5: Did auxin play a crucial role in the evolution of novel body plans during the Late Silurian--Early Devonian radiation of land plants?

Chapter 5 of the book "Evolution of Plant Physiology," is presented. It explores whether developmental mechanisms may have contributed to the rapid diversification of early land plant lineages during the Late Silurian to Early Devonian Periods. It offers an overview of Cambrian radiation of bilateral animals to consider the analogous radiation of early land plants. Evidence gathered by the research has confirmed that early land plants did undergo a rapid evolutionary radiation during the Late Silurian to Early Devonian periods.
