Chapter 20 PHYLOGENY Introduction to Phylogeny Phylogeny is the evolutionary history of a species or group of related species Discipline of systematics classifies organisms and determines their evolutionary relationships Taxonomy is the ordered division and naming of organisms Cladistics Cladistics classifies organisms by common descent A clade is a group of species that includes an ancestor and all its descendents Using Derived Characters Characters can be used to infer evolutionary relationships. Molecular Clocks Molecular clocks use mutation data in related genes from different species Number of nucleotide changes is assumed to be proportional to the time since last common ancestry ie. Few changes = little time passed; many changes = lots of time passed

Arthropod Coloring Worksheet Arthropods (jointed appendages) are a group of invertebrate animals in the Kingdom Animalia. All arthropods have a hard exoskeleton made of chitin, a body divided into segments, and jointed appendages (mouthparts, antenna, and legs). Three main groups of the arthropods include the insects, arachnids, and crustaceans. What does arthropod mean? In what kingdom are arthropods found? Are they vertebrates or invertebrates? Why? (see textbook) List 3 characteristics of all arthropods. Name 3 main arthropod groups. Insects
