Which is the form of protozoan reproduction that generates more variability?
Sexual reproduction always generates more genetic variability than asexual reproduction. That is because in sexual reproduction the fusion of genetic material from different individuals occurs and so the offspring is not genetically identical to the parent cell. If the hypothesis that protozoans originated multicellular animals is strong, other hypotheses may be even stronger: that these protozoans were able to reproduce sexually, since only genetic variation can produce biological differentiation to the point of creating new types of living beings.
