1. Cladograms Diagrams that show how groups of species are related – common ancestry The most inclusive group (ie. all got the same major characteristics) is at the bottom http://www.teachersdomain.org/folder/view/ 1559002/

2. Breath with Lungs Parental care of young Lizard-hipped Adapted for frequent locomotion Flying ! 25 vertebrae Bird-hipped

3. Cladograms Branches do not mean extinction – simply that the new species (ie. lizards) has not developed feathers, but all living birds have the same ancestor as lizards and dinosaurs Birds actually evolved from lizard-hipped dinosaurs, not the bird-hipped dinosaurs – this characteristic developed independently http://www.teachersdomain.org/folder/view/ 1559002/

4. Construct Your Own Cladograms Identify common traits (use 0 if absent, 1 if present) In pairs, draw a simple cladogram, labelling each trait in the correct place
