Actually, it is thought (I am not sure how widely) that plants came from an ancestral fungia and that animals came from an ancesteral sponge-like structure.Originally posted by FZ+
Maybe there is a genetic connection here.
Perhaps Plants etc represent a different branch of the tree of life, and animals/sponges share a branch, being shown by genetic retracing of evolution?
That is old classification. With 18s and 16 s ribosomal RNA, there is 3 domain Bacteria, Archea and Eucarya, then each Domain is seperated in kinggom. rigth now the kingdoms for Eucarya are animalia, plantae, fungi and protista but many fungi migth be displaced and prostita migth be exploded into different kingdom.Originally posted by Sikz
Fungi are actually classified in their own kingdom- There are currently five, I believe. Kingdom fungi (fungi), kingdom animalia (animals), kingdom plantae (plants), kingdom protista, kingdom monera. I think scientists are considering a sixth group, but it isnt concretely established. :)
I would say that green algae are more likely to be the ancestor of plant but it seems that plants, animal and fungi have a common ancestor closer than previously though.Originally posted by Sikz
