natural selection - process by which organisms with traits best suited for the environment survive and reproduce; process by which evolution occurs, adaptation - any trait that allows organism to survive and reproduce; = biological fitness, common ancestor - shown by fossils, DNA and amino acid sequences and homologous structures; shows evolution; represented in phylogenetic trees, virus - has nucleic acids (DNA or RNA) and protein coat (capside); infects host cells to reproduce; NON-LIVING, bacteria - prokaryotic cell with NO nucleus; has peptidoglycan in cell walls and killed by antibiotics; can be beneficial or pathogens, archaea - prokaryotic cell that lives in EXTREME environments; has cell walls but NO peptidoglycan - examples include halophiles, thermophiles and methangoens, protists - uni or multicellular aquatic eukaryotes; mostly aquatic- examples include amoeba, euglena and paramecium, fungi - unicellular (yeast) or multicellular (mushrooms) heterotrophic eukaryotes, plants - eukaryotic, multicellular autotrophs (do photosynthesis) some have vascular tissue (xylem and phloem); some have seeds in cones (gymnosperms) and some have flowers and seeds (angiosperms), animals - multicellular heterotrophs; invertebrates or vertebrates (with backbone),
