okay looking good looking good okay I want to start here with the role of microbes in eukaryotic evolution and what I'm showing here is a is a phylogenetic tree that shows the evolutionary relationships among the three major domains of life which of course include bacterial eukaryotes and archaea what's what I want to point out in this particular tree is that bacteria and archaea as Sarah mentioned have been on the planet for much longer than eukaryotes have so they evolved 3.8 bacteria of all 3.8 million years ago bacteria evolved before archaea about a billion years ago is when animals started to arise and what I'd like to note is that most of the diversity in this tree is in fact microbial so if you're looking at evolution from a genetic diversity perspective virtually all of the major lineages of life are either in the back bacteria archaea or in eukaryotes certain such as protists there's a small group of eukaryotic organisms at this end of the tree and that comprise everything th
