Ferns are the most abundant group of
seedless vascular plants, with about
12,000 living species. Recent research indicates
that they may be the closest relatives
to the seed plants. The fossil record
indicates that ferns originated during the Devonian period
about 350 million years ago and became abundant and varied
in form during the next 50 million years. Their apparent
ancestors had no broad leaves and were established on
land as much as 375 million years ago.
