  1. INDEP Day 13. How do the physical features Linnaeus used reveal evolutionary relationships? Time is now up for the Do Now! One Five Two Three Four minute(s) for Do Now Six • To answer the question: • List the characteristics that biologists use to classify organisms • Read a cladogram • Ancestral character • Derived character • Vocab for today: • Cladistics • Phylogeny • Cladogram @MrLinehan HW or study questions?

  2. WHOLE Agenda • WHOLE: Review of Do Now • WHOLE: Guided notes • COOP: Stand up, hands up, pair up • INDEP: Practice worksheet • ASSESS: Exit quiz • Check-out

  3. WHOLE The Do Now.Let’s review.

  4. WHOLE Phylogeny Phylogeny is just the evolutionary history of a species. (How natural selection caused its unique speciation.)

  5. WHOLE Cladistics Cladistics is the method we use to analyze and represent phylogeny (evolutionary history). This tells us about evolutionary relationships, just like taxonomy!

  6. WHOLE Cladogram Cladograms are graphic organizers we use to represent phylogeny.

  7. WHOLE Cladogram

  8. WHOLE Ancestral characters Ancestral characters are features shared by two species because of a common ancestor. On a cladogram, they appear before the spot where two species branch apart. Indicate closer evolutionary relationship.

  9. WHOLE Derived characters Derived characters are features that only one of two species has because the adaptation emerged after the species split. On a cladogram, they appear after the spot where two species branch apart. Indicate more distant evolutionary relationship.

  10. WHOLE COOP Stand up, hands up, pair up • Each person receives a vocab flashcard and becomes an expert on that word • You stand up and raise your hand, looking for an available partner with a hand up • Walk over and high five • Quiz each other on your words • Trade cards and find new partner You should exchange cards at least 10 times in 7 minutes.

  11. INDEP Independent practice 8 minutes to complete practice section. (Otherwise homework.)

  12. ASSESS Exit quiz • Answer multiple choice on clickers using the student code in your binder. • ASSESSexpectations will apply • Anytalking or materials on the desk will result in a 0. • It must be silent until every person has turned in the test.

  13. INDEP Track your score Record your score in the “score one” column of the third row of your unit 2 cover sheet

  14. ASSESS Exit quiz make-up • Important instructions: • Do not right in test packet. • Answer multiple-choice on clickers. If desired, back up your answers on a Scantron sheet. (Raise your hand to request one.) • Anytalking or materials on the desk will result in a 0 on that section of the exam. • It must be silent until every personhas turned in the test.

  15. WHOLE Exit procedures • Line up in back • Chairs pushed in (A3 & B7 - on tables) • Area cleaned up • Nothing left in the room! • Get today’s participation score, MissionBucks, and afternoon passes from Mr. Linehan
