Day 13. How do the physical featuresLinnaeus used reveal evolutionary relationships?

HW or study questions? @MrLinehan

INDEP

To answer the question:• List the characteristics

that biologists use to classify organisms

• Read a cladogram

Vocab for today:• Cladistics• Phylogeny• Cladogram

• Ancestral character• Derived character

WHOLE

The Do Now.Let’s review.

WHOLE

PhylogenyWHOLE

Phylogenyis just the evolutionary history of a species.

(How natural selection caused its unique speciation.)

CladisticsWHOLE

Cladisticsis the method we use to analyze and represent phylogeny

(evolutionary history).

This tells us about evolutionary relationships, just like taxonomy!

CladogramWHOLE

Cladogramsare graphic organizers we use to represent phylogeny.

CladogramWHOLE

Ancestral charactersWHOLE

Ancestral charactersare 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 charactersWHOLE

Derived charactersare 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 five4. Quiz each other on your

words5. Trade cards and find new

partner

Stand up, hands up, pair upWHOLECOOP

You should exchange cards at least 10 times in

7 minutes.
