Ameobae are psuedopods. It means "false foot". They form a little extension of their cytoplasm and push the rest of their bodies into it.

I believe the tree for Protists are one big polytomy… we can’t really figure how any other them are related. But I think maybe they know a few of the Subphylums are.

I like protists, so we can still talk about them, right? So interesting because their evo is so far back, it is hard to tell the evo of these little guys!

it depends on what type of tree you’re looking for: according to classical or molecular systematics. Now we classify the Protista by the degree of endosymbiosis.

Could you lead me to information on that tree? That is pretty neat stuff.

unfortunately systematics if one of the last things on my list of preferences, so your guess is as good as mine.

kingdom "protista" is a paraphyletic taxon, which means they represent quite diverse eukaryotic lineages which do not have a most recent common ancestor that excludes the other eukaryotes, and do not truly adhere to phylogenetic classification. hence there can be no tree of all protistans which does not include plants, animals and fungi.

oortclouddomicile – how can be that protista has no common ancestor? If Eucarita has, also protista has to – same this one. And Eucariota is mophyletic undoubtedly… But… protista is extrimly divesed "group" and differensies from grin and red algue for examle is extrimle wide. It’s one probleme, and other one that some of the grops is "secondary monocellular" ‘ amog fungies (if I am correcct it’s baker yest) and some parasisits from "animal part" of the protists… i don’t remember the names…

i did not say Protista do not have a common ancestor. yes, all life on Earth has to have a common ancestor. what i meant was that in the case of Protista, not all the descendants of the last common ancestor are Protistans; the descendants also include plants, animals and fungi, which are all placed in separate Kingdoms.
Class Reptilia is another example of such paraphyletic classification, wherein, the descendants of the last common ancestor of all extant and extinct reptiles also include the mammals and the birds which are both accorded Classes of their own.
