Document Summary
Classic approach is based on latin binomial and hierarchy. Modern terms have largely replaced hierarchy with more nuanced. Phylogeny: show common ancestors, time since branching, there isn"t just one way to make a phylogeny, can be rearranged without changing info, analogy convergent evolution same but not found in a common ancestor. Mess up phylogenies: monophyletic groups trace back to common ancestor then monophyletic) trace forward to all descendants (same set . Most life we are familiar with and can see with the naked eye are eukaryotes (animals, plants, fungi, algae) Eukaryotes are opposite of prokaryotes: they have no cell wall or cell wall not composed of, they have internal organelles such as golgi apparatus, peptidoglycans mitochondria (energy processors), and sometimes chloroplasts (photosynthesis) Dna and ribosomes are already attached to membrane, keep folding until they"re surrounded (nucleus / golgi apparatus) Extend cytoskeleton to flagellum and develop motion.
