The Do Now. Let’s review. WHOLE

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

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

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

Cladogram WHOLE

Ancestral characters WHOLE 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.

Derived characters WHOLE 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.

1.Each person receives a vocab flashcard and becomes an expert on that word 2.You stand up and raise your hand, looking for an available partner with a hand up 3.Walk over and high five 4.Quiz each other on your words 5.Trade cards and find new partner Stand up, hands up, pair up WHOLE COOP You should exchange cards at least 10 times in 7 minutes.

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

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

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

Exit quiz make-up ASSESS 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.) Any talking or materials on the desk will result in a 0 on that section of the exam. It must be silent until every person has turned in the test.
