Evolution Of Eukaryotes Prokaryotic cells and eukaryotic cells are the two types of cells that exist on Earth. Evolutionary scenarios for the origin of eukaryotes and their impact on the reconstruction of virus evolution The origin of eukaryotes is Summray: major problem in evolutionary biology that is generally considered to be unresolved. Eukaryotes and archaebacteria are the two most closely related of the three. Eukaryotes originated later than thought in evolution.

Summary: The Neoproterozoic Era

Overall, the genesis of eukaryotes remains mysterious because all eukaryotes alive today arose from an organism that was already complex. Cells of animals, plants and fungi are called eukaryotic cells. It may also have had a hand in the evolution of more complex cells, called eukaryotes, that later came became multicellular organisms. Actually the evolution of Eukaryotes still remains a non-validated hypothesis.

The slow, steady changes found in DNA over time, known as mutations, which can be destructive, Summary: The Neoproterozoic Era, or beneficial to an organism, are at the core of the theory of evolution. And some of these control mechanisms may have been co-opted by the eukaryotic cell, evolving into the complex system of regulated cell death that is so essential to multicellular life.
