Recent divergence time estimates suggest they may be even older, possibly having first evolved as far back as 430 mya (Testo and Sundue, 2016). That is, until you look closely at the detail of their fronds and run your fingers down the stalks. Seed ferns are entirely extinct. During the age of the dinosaurs, ferns and other primitive plants such as club mosses and horsetails reached magnificent proportions, many over one hundred feet tall. Although they have a worldwide distribution, ferns are more common in tropical and subtropical regions. Their survivability is on another level compared to other kinds of plants, since they have evolved in such way to be able to survive the extremeness of meteor crash, global warming, and ice age.

They live in shady places that provide enough moisture, such as forests, fields, swamps and areas near the streams. The reason this asexual reproduction happens is usually because of the surrounding environment is too dry. The oldest known seed plants are called "seed ferns".

This name is misleading since the they are not ferns at all despite the superficial similarity of their leaves to those of ferns. With so many ferns to choose from, selecting the right one can be daunting. Uniquely, the asexual reproduction is usually done when the ferns are facing hard times to do the normal reproduction.

That’s because many plants need good light for their seedlings to establish and this may not be available on the forest floor. Several kinds of ferns are about the same age as Gingko. The stem of the tree fern is made up of all of the retained leaf bases of the fronds from previous years. As time goes, the baby grows bigger and heavier, making the fronds are bowing down to the earth and make the baby ferns separated from the mama. As time passes, the tree species may completely grow over the tree fern, engulfing the tree fern stem into its trunk. That’s because growth, even of the roots, originates from part of the apex of the stem. What are the oldest living plant species on Earth? How Can Pioneer Species Change Entire Ecosystem By Itself? As a plant group, tree ferns are ancient, dating back hundreds of millions of years and pre-dating dinosaurs. Today’s ferns, the descendants of those ancient plants, include more than 10,000 living species, second only to angiosperms or flowering plants. These ferns were one of the first big plants to live on land and helped make oxygen, which made the land ready for other life to start living too. They survived the meteor crash that killed the dinosaurs, and they also survived the extreme temperature of ancient global warming and ice age. The earliest were vine-like plants, probably less than two meters tall, that probably grew epiphytically on other plants for structural support. Mainly, that’s how they evolved to adapt to the environment. The oldest plants on earth serve as modest ballasts in floral arrangements, as well as in life.
