Root development has been crucial for the success of vascular plants in terrestrial ecosystems, but not all rooting systems evolved from a common ancestor. Fossil evidence suggests that root development evolved independently at least twice over the course of land plant evolution, once within the euphyllophyte lineage, consisting of the seed plants and ferns, and once within the lycophyte lineage.

The importance of plant roots for our planet cannot be overstated. They provide numerous ecosystem services that support life on Earth, including soil stabilization, nutrient cycling, carbon sequestration, and food production. Protecting and preserving healthy root systems is essential for maintaining the sustainability of our planet's ecosystems and ensuring the well-being of future generations.
