Document Summary
Phylogenies are inferred from morphological and molecular data. Shared characters are used to construct phylogenic trees. An organism"s evolutionary history is documented in its genome. 26. 6 new information continues to revise our understanding of the tree of life. The evolutionary history of a species or group of species. A phylogeny of lizards and snakes indicates that both the scaly-foot and snakes evolved from lizards with legs but that they evolved from different lineages of legged lizards. Thus, it appears that their legless conditions evolved independently. The scientific discipline of how organisms are named and classified. Common names for organisms can cause confusion (i. e. monkey, finch, etc. ) since each of these names refer to more than one species. Some common names do not accurately reflect the kind of organism they signify. Three "fishes": jellyfish (cnidarian), crayfish (small lobster-like crustacean), and silverfish (insect) A given organism has different names in different languages.
