Alternative pathway (cyanobacteria to eukaryota)

1994
It is quite evident from the fossil record that prokaryotic cells were the first cell type evolved. After a long interval of nearly two billion years eukaryotic cells appeared. There is little doubt that this cell type arose from the bacterial cell. How this occurred has been the subject of much speculation.

The ultrastructure of Carpediemonas membranifera (Eukaryota) with reference to the “excavate hypothesis”

European Journal of Protistology, 1999
Summary The ultrastructure of Carpediemonas membranifera , a small flagellate isolated from marine intertidal sediments, is presented for the first time. This protist has two flagella inserting at the anterior end of a feeding groove. The posterior flagellum bears three vanes. The cell has an anterior nucleus, a single dictyosome and a hydrogenosome-

Evoluce skupiny Retortamonadida (Eukaryota: Excavata: Fornicata)

2010
Retortamonads (Retortamonadida; genera Chilomastix and Retortamonas) are a small group of protists comprising intestinal commensals of both vertebrates and invertebrates and one free-living species of the genus Chilomastix. Molecular phylogenetic studies showed that retortamonads are closely related to diplomonads, Carpediemonas, Dysnectes ...

Origin of eukaryota from Cyanobacterium: membrane evolution theory

1994
It has been currently estimated that the life generated about four billion years ago in the primitive sea as a result of the chemical evolution. There is no doubt that, at that time, the protoorganism was a prokaryotic monad, formed from a certain aggregate of primitive proteins, nucleic acids, and other macromolecules and wrapped with (phospho)lipid ...
