Evolutionary microbiologists developed a theory about a common ancestor for all eukaryotic cells. Below is a model of the theorized changes during the origin of eukaryotic cells. Prokaryotes are not capable of phagocytosis, or engulfing outside particles by creating a pocket in the cell membrane.
Which of the following changes in early prokaryotes could be predicted to result in the emergence of eukaryotic organisms?
A - the development of genetic transfer mechanisms in prokaryotes
B - the evolution of predatory or
C - the emergence of collections of cells functioning together in prokaryotes
D = the expansion of internal structures to support larger individual cells in prokaryotes
