Protozoa Evolve

2 Billion Years Ago (+/- 100 million years)
Nucleus and internal organelles

About two billion years ago, early single-celled eukaryotic lineages diversified. Multiple branches emerged during this period, some of which would later give rise to animals, plants, and fungi. Among these were motile, heterotrophic forms traditionally called protozoa — representatives of several early eukaryotic branches, many of which still survive today.
