Ferns: Survivors from the Dinosaur Era
Ferns, with their underground rhizomes and ability to grow back even after being damaged, have proven to be resilient plants that have survived for millions of years. They have been around since before the time of the dinosaurs, although most of the fern species we see today evolved more recently. Ferns are found worldwide and thrive in various climates, even including deserts. One reason for their widespread distribution is their unique method of reproduction through spores, which can travel long distances through the air. Ferns played a crucial role in the Earth's recovery after the mass extinction event that wiped out the dinosaurs, as they created fertile soil and allowed other plants to grow.
