How different are the ferns we have now compared to the earliest ones? Have they remained mostly unchanged? If not whats the oldest plant species on earth now that has changed the least?
I study for 30 yrs. Just to reproduce this ferns I have known that birdsnest has pores at the back of Thier leaves but then I find it since I don't have the equipment plus the knowhow to do it And I was able to reproduce by taking the baby plants that grows around our sorrounding specially in the coconut tree That is my source of my seedling And let it grow in the owns roots what is hard to wait for 30 yrs to have a mother plant In which I was lucky enough to have a 6 mother plant as source of my nedium
