The PEDIGREE of
Complex mitochondrial life
   (sexual reproduction began ca 1200 M BC, leading to much faster evolution rate)

    External page: ``Tree of Life'' -- a beautiful site.
 
    Note: Parts of the tree of life are still controversial, for two reasons: (1) much evolution occurred in brief flurries like the Cambrian revolution 600 million years ago; (2) Cross-species genetic transfer (in which a species has no single clearcut ancestor), while rare, probably was responsible for many key advances.
   Thus plants and animals both evolved from early eukaryotes, which differentiated rapidly 1 billion years ago, after ingesting prokaryotes -- photosynthesizing prokaryotes in the case of plants, or oxidizing in the case of animals. (I even thought of using the ``mother'' branch of the pedigree to suggest such genetic transfers!)
