Evolution of Eukaryotes

Mitochondria in eukaryotic cells and chloroplasts in plant cells have evolved from free-living bacteria.

  • Present-day cells evolved from a common prokaryotic ancestor along 3 lines of descent, giving rise to archaebacteria, eubacteria, and eukaryotes
  • The first eukaryotic cells evolved about 2 billion years ago, this is explained by the endosymbiotic theory.
  • Endosymbiosis came about when large cells engulfed small cells where the small cells were not digested by the large cells instead, they lived within the large cells and evolved into organelles.
  • From independent cell to organelle the large and small cells formed a symbiotic relationship in which both cells benefited.
  • Mitochondria - Some of the small cells were able to break down the large cell’s wastes for energy.
  • They supplied energy not only to themselves but also to the large cell.
  • They became the mitochondria of eukaryotic cells.
  • Chloroplasts - Other small cells were able to use sunlight to make food.
  • They shared the food with the large cell.
  • They became the chloroplasts of eukaryotic cells.
  • The ancestor of mitochondria was a proteobacterium that was engulfed by an asgard archaean organism.
  • Descendants of this endosymbiotic union gave rise to animals, fungi and plants.
  • In plants, the asgard-mitochondrial union was followed by the intake of a photosynthesizing cyanobacterium, which became the chloroplasts.
