The ferns and their relatives first appear in the fossil record some 360 million years ago in the late Devonian period. They diversified into many of the modern fern families and species during the ...

If evolution is absolute then those ferns developing dimorphism would not shift their course back to monomorphism. Using the natural history collections and algorithms for estimating evolution ...

However, using natural history collections and algorithms for estimating evolution in ferns, Smith and I found exceptions to this pattern. Within a family known as chain ferns (Blechnaceae), we ...

Focus: Tracking the evolution of fern diversity through space and time We are tracking the evolution of fern diversity through space and time. This project aims to explore the origin of fern diversity ...

To the contrary, we found that in many types of ferns – one of the oldest groups of plants on Earth – evolution of reproductive strategies has been a two-way street, with plants at times ...

Throughout their evolution, ferns have undergone a series of changes that have helped them survive on land. For the first time, researchers have characterized the genome arrangement of tree ferns ...
