Eukaryote Evolution: Symbiosis & Beyond

[chalky]

hello
i'm new here and looking for some help with my assignment.
i am currently working on an assignment about how the eukaryote evolved from the prokaryote, currently i have come across only one theory which is symbiosis, i need to find several theories and was wondering if anyone here had heard of any others.
help would be greatly appreciated as biology is not my strong point!
thanks to anyone who can help

One of the newer theory is that eukaryotes did not evolve from prokaryotes and started to develop on their and eventually formed symbiosis.
