The Endosymbiotic theory that is other wise known as the symbiogensis illustrates the occurrence of the eukaryotic cell from the prokaryotic cells. Mitochondria and plastids are the most studied example in support of this theory. This theory explains that the aforementioned organelles are formed as they are taken inside in one another by the prokaryotic cell. Some of the evidences in support of this theory are mentioned below:

  • Phylogenetic similarity between the mitochondria and chloroplast to the proteobacteria and cynobacteria respectively.  
  • Ability of these organelles to divide only through binary fission as the bacterial population.
  • The associated ribosomes are similar to the bacterial ribosomes.

5. no because they could be sister taxa, you would have a hard time proving exactly that this new fossil is the common ancestor that birds came from to replace the old hypothesis (guess) of which one did.
