Bacteria and soft body  animals were present during this period. The natural selection which id reproduction and the way they feed. Bacteria reproduces by binary fission and absorbs its food. Genetic flow or migration was found in bacteria which is its genes carried to another. It took over 2 billion years for the bacteria to connect and become multi-cellular organisms. Bacteria's genetic drift is just genes transferring to one another. The homologous structures in this time were skeletons from soft body creatures. Some organs were the appendix, and tailbone. The molecular evolution for this period was a "DNA molecular

happened over 440 million years ago. Were marine life started to die off for example brachiopod and bryozoan families. These families reproduce asexually, there also what are called suspension feeders. Mutations in this period were good and bad these families also have whats called Sexual Dimorphism. Vestigial organs in these families were tissues and a gut.

Had happened 365 million years ago. Almost every marine animal went extinct. Not a lot reproductions or feeding there wasn't a lot around during this time or a lot of marine activity at this point but vertebrates were still doing there thing.

Had happened 250 million years ago. In this time the largest mass extinction in earths history had affected many species even some vertebrates. they reproduce by sexual interaction and feed by catching and killing or if herbivores eat plants.

Had happened around 210 million years ago  other vertebrates went extinct and on land let dinosaurs  to developed. reproduction was sexual interaction and feed like other vertebrates.
