caldogram help
I can't figure this out. I don't understand how to put the traits that corrospond to each line. So what im supposed to do is to illustrate the caldogram with diagnostic characteristics for groups 1-7 (Dinosauria, Saurischia, Theropoda, Tetanurae, Maniraptora, Avialae, modern birds) to show how modern birds originated from dinosaurs. But i get too confused about which line corrosponde to which trait.
Options i able to put in is 1. Bird-like pelvis 2. Reptilian pelvis 3. Bipedal 4. Quadripedal 5. Upright position 6. Vertical position 7. Feathers 8. Asymmetrical feathers 9. Three-fingered hands 10. Three-toed feet 11. Forked legs 12. Hollow bones 13. Teeth missing 14. Extension of arms 15: Compound metatarsals.
And on line 3, 4 and 5 im supposed to put two options.
First of all do i begin with bird-like pelvis due to the branch that leads to Ornithischia? or? All the lines makes me confused. Even tho i have the answers and know the facts all the lines makes my brain not work.
Help please!
